RESUMO
Introdução: Na medida em que envelhecemos os lábios estreitam-se, ocasionando perda de volume e contorno e como forma de minimizar este efeito fisiológico o preenchimento labial de escolha utilizado é o ácido hialurônico. É possível perceber efeitos adversos advindos do emprego deste material, e pelo fato da informação ao paciente ser assegurada pelo Código de Defesa do Consumidor e pelo fato da necessidade dos Cirurgiões-Dentistas terem de esclarecer seus pacientes, o Termo de Consentimento Livre e Esclarecido tornase necessário. Objetivo: identificar, por meio de aplicação de questionário, a percepção de profissionais que trabalham com Harmonização Orofacial em relação a necessidade do emprego do Termo de Consentimento Livre e Esclarecido (TCLE). O questionário apresentou 6 perguntas objetivas, que foram disponibilizadas na plataforma Google Forms®. Material e Método: os dados obtidos foram tabulados em uma planilha eletrônica do programa Microsoft Excel e após analisados descritivamente através de tabelas de frequência, porcentagens e gráficos estatísticos. Resultados: dentre os entrevistados foi constatado que a maioria, 87,5% dos especialistas em Harmonização Orofacial realizam o procedimento de preenchimento labial em sua rotina clínica, e 12,5% não. Conclusão: no presente estudo identificamos que os especialistas realizam o emprego do TCLE, em sua maioria, porém, alguns destes ainda negligenciam o seu uso(AU)
Introduction: As we age, the lips become thinner and to minimize this effect, the lip filler used is hyaluronic acid. It is possible to notice adverse effects arising from the use of this material, and it is extremely important that Dental Surgeons have to clarify their patients, the Free and Informed Consent Form becomes necessary. Objective: to identify, through the application of a questionnaire, the perception of professionals who work with Orofacial Harmonization in relation to the need to use the Free and Informed Consent Form (TCLE). The questionnaire presented 6 objective questions, which were made available on the Google Forms® platform. Materials and Methods: the data obtained were tabulated in a Microsoft Excel spreadsheet and then analyzed descriptively using frequency tables, percentages and graphs. Results: among those interviewed, it was found that the majority, 87.5% of specialists in Orofacial Harmonization perform the lip filling procedure in their clinical routine, and 12.5% do not. With the high percentage of 59.4%, it was possible to verify that the majority of professionals perform 1 to 3 procedures per month; 31.3% perform 4 to 9 procedures per month; and 9.4% of 10 or more monthly procedures. Conclusion: in the present study it was possible to identify that the majority of specialists in Orofacial Harmonization use the informed consent form, however, some of them still neglect its use(AU)

A 49-year-old female with no pre-morbidities comes in with sudden, painless loss of vision in the left eye (OS) after a facial hyaluronic acid (HA) injection for aesthetic purposes one hour ago. Visual acuity was no light perception (NLP). OS examination revealed a mid-non-reactive mydriasis and complete ophthalmoplegia. Fundus examination of the OS suggested central retinal artery occlusion (CRAO). Systemic evaluation was normal. Given this diagnosis, ocular massage, anterior chamber paracentesis, anticoagulation, systemic antibiotherapy, and subcutaneous hyaluronidase around the injection sites and peribulbar region were performed. Despite these interventions, the patient did not regain vision, exhibiting signs of anterior and posterior ocular ischemia. Subsequently, she developed phthisis bulbi, necessitating evisceration. The management of this complication should be prompt, if possible, to mitigate its dire consequences.
RESUMO
OBJECTIVE: To evaluate with an animal model of osteoarthritis (New Zealand rabbits) the effectiveness of treatment with active viscosupplements (hyaluronic acid loaded with nanoparticles (NPs) that encapsulate anti-inflammatory compounds or drugs. MATERIAL AND METHODS: Experimental study composed of 5 groups of rabbits in which section of the anterior cruciate ligament and resection of the internal meniscus were performed to trigger degenerative changes and use it as a model of osteoarthritis. The groups were divided into osteoarthrosis without treatment (I), treatment with commercial hyaluronic acid (HA) (II), treatment with HA with empty nanoparticles (III), treatment with HA with nanoparticles encapsulating dexamethasone (IV) and treatment with HA with nanoparticles that encapsulate curcumin (V). In groups II to V, the infiltration of the corresponding compound was carried out spaced one week apart. Macroscopic histological analysis was performed using a scale based on the Outerbridge classification for osteoarthritis. RESULTS: We observed that this osteoarthritis model is reproducible and degenerative changes similar to those found in humans are observed. The groups that were infiltrated with hyaluronic acid with curcumin-loaded nanoparticles (V), followed by the dexamethasone group (IV) presented macroscopically less fibrillation, exposure of subchondral bone and sclerosis (better score on the scale) than the control groups (I) (osteoarthritis without treatment), group (II) treated with commercial hyaluronic acid and hyaluronic acid with nanoparticles without drug (III). CONCLUSIONS: The use of active viscosupplements could have an additional effect to conventional hyaluronic acid treatment due to its antioxidant and anti-inflammatory effect. The most promising group was hyaluronic acid with nanoparticles that encapsulate curcumin and the second group was the one that encapsulates dexamethasone.
RESUMO
Pseudoseptic arthritis is a rare complication of hyaluronic acid (HA) injections that often is difficult to differentiate from septic arthritis. Patients present acute pain, swelling and joint effusion normally around 24h after the second or third HA infiltration. We describe a female patient with seropositive rheumatoid arthritis and flare-ups of knee arthritis with pseudoseptic features in the past, who develops pseudoseptic arthritis of the knee following her first injection of hyaluronic acid.

INTRODUCTION: Traumatic spinal cord injury (SCI) leads to increased intraspinal pressure that can be prevented by durotomy and duroplasty. The aim of the study was to evaluate fibrosis and neural damage in a porcine model of SCI after duroplasty and application of hyaluronic acid (HA) in the tissue cavity. MATERIALS AND METHODS: Experimental study. We created a porcine SCI model by durotomy and spinal cord hemisection of a cervical segment (1cm). Six pigs (Sus scrofa domestica) were used to evaluate three surgical scenarios: (1) control injury with dural reparative microsurgery, (2) duroplasty using bovine pericardium (BPD), and (3) previous method plus HA applied at the lesion. Animals were sacrificed one-month post-injury to assess fibrotic responses and neural tissue damage using conventional histological and immunohistochemical methods. RESULTS: In the control case, dural suture prevented invasion of the lesion by extradural connective tissue, and the dura mater showed a 1-mm thickening in the perilesional area. The bovine pericardium patch blocked the entrance of extradural connective tissue, decreased dura-mater tension, and satisfactorily integrated within the receptor tissue. However, it also enhanced subdural and perilesional fibrosis, which was not inhibited by filling the lesion cavity with low- or high-molecular-weight HA. CONCLUSIONS: Duroplasty prevents collapse of the dura-mater over the spinal cord tissue, as well as invasion of the lesion by extramedullary fibrotic tissue, without creating additional neural damage. Nevertheless, it enhances the fibrotic response in the spinal cord lesion and the perilesional area. Additional antifibrotic strategies are needed to facilitate spinal cord repair.
RESUMO
ABSTRACT Purpose: Recently, hyaluronic acid (HA) was proposed as a promising option for the treatment of acquired lower eyelid cicatricial ectropion. However, this effect was not confirmed by quantitative assessments. This study aimed to assess the effect of hyaluronic acid on the treatment of acquired lower eyelid cicatricial ectropion. Methods: Eight patients with acquired lower eyelid cicatricial ectropion (13 eyelids) were treated with a single 1 mL injection of hyaluronic acid in the preseptal area of the lower eyelid. Evaluation of symptoms and biomicroscopic exam was performed before and 30 days after hyaluronic acid injection. Quantitative analysis of the lower eyelid position (with and without lid traction) was determined before and 30 days after hyaluronic acid injection through standard photographs analyzed using the ImageJ. Results: All patients experienced partial improvement of symptoms. The lower eyelid position was significantly lifted after hyaluronic acid injection with a significant reduction of medial and lateral angles, reduction of the margin reflex distance, and total and medial ocular fissure area. However, signs of lid margin inflammation and corneal punctate keratitis persisted. Conclusions: Hyaluronic acid injected in the pre-septal area of the lower eyelid improved acquired lower eyelid cicatricial ectropion symptoms and significantly lifted the position of the lower eyelid. Further studies, with a large number of participants and a long-term follow-up period, are needed to better determine the permanency of the effects of hyaluronic acid injections on the treatment of acquired lower eyelid cicatricial ectropion.
RESUMO Objetivo: Recentemente, o ácido hialurônico foi proposto como promissor no tratamento do ectrópio cicatricial adquirido da pálpebra inferior. No entanto, não foram feitas avaliações quantitativas para confirmar este efeito, motivo que levou a realização do presente estudo que visou avaliar o efeito do ácido hialurônico no tratamento do ectrópio cicatricial adquirido da pálpebra inferior. Métodos: Oito portadores de ectrópio cicatricial adquirido da pálpebra inferior (13 pálpebras) foram tratados com uma única dose de 1 mL de ácido hialurônico, injetada na área pré-septal da pálpebra inferior. Os sintomas e o exame biomicroscópico foram realizados antes e 30 dias após a injeção do ácido hialurônico. A análise quantitativa da posição palpebral inferior (com e sem tração palpebral) foi determinada antes e 30 dias após a injeção do ácido hialurônico por meio de fotografias que foram analisadas usando o programa ImageJ. Resultados: Todos os pacientes apresentaram melhora parcial dos sintomas. A posição da pálpebra inferior foi elevada significativamente após a injeção do ácido hialurônico, com redução significativa dos ângulos medial e lateral, da distância entre o reflexo pupilar e a margem da pálpebra inferior, da área de fissura palpebral total e da área medial. No entanto, sinais de inflamação da margem palpebral e ceratite puntata da córnea persistiram. Conclusões: O ácido hialurônico injetado na área pré-septal da pálpebra inferior, melhorou os sintomas do ectrópio cicatricial adquirido da pálpebra inferior e elevou significativamente a posição da pálpebra inferior. Estudos com maior número de participantes e período de acompanhamento mais longo são necessários para melhor determinar os efeitos das injeções de ácido hialurônico a longo prazo no tratamento do ectrópio cicatricial adquirido da pálpebra inferior.
RESUMO
ABSTRACT Objective: The objective of the present prospective case control study was to evaluate the facial pleasantness of patients with complete and unilateral cleft lip and palate at the end of interdisciplinary rehabilitation, submitted to facial fillers based on hyaluronic acid. Methods: The study group consisted of 18 individuals with complete unilateral cleft lip and palate, aged between 18 and 40 years (mean age 29 years) of both sexes. The patients presented a concave profile with mild to moderate maxillary deficiency, with completed orthodontic treatment and conducted by means of dentoalveolar compensations without orthognathic surgery. Participants underwent facial filling procedures with hyaluronic acid (HA) in the midface, inserted by a single operator. Standard photographs in frontal norm at rest, right profile at rest, and left profile at rest were obtained from each patient at the following operative times: (T1) pre-filler and (T2) and one-month post-filler. The photographs in T1 and T2 were randomly placed on a page of a virtual album. A 5-point Likert scale was used to assess facial pleasantness. The photographs were evaluated by two groups of evaluators consisting of 18 individuals with cleft lip and palate (CLPG=18) and 18 orthodontists with experience in the treatment of clefts (OG=18). For comparison between phases T1 and T2, and between evaluators with orofacial clefts and orthodontists, the Wilcoxon test was used (p<0,05). Results: People with cleft lip and palate rated their face as more pleasant after the midface filling procedure. In the perception of the orthodontists, on the other hand, the facial pleasantness remained similar after the facial filling procedure. Conclusions: The filling of the middle third of the face in patients with cleft lip and palate treated without orthognathic surgery increased the pleasantness of the face in the opinion of laypeople with cleft lip and palate.
RESUMO Objetivo: O objetivo do presente estudo caso-controle prospectivo foi avaliar a agradabilidade facial de pacientes com fissura labiopalatina completa e unilateral ao final da reabilitação interdisciplinar, submetidos a preenchimentos faciais à base de ácido hialurônico. Métodos: O grupo de estudo foi composto por 18 indivíduos com fissura labiopalatina unilateral completa, com idade entre 18 e 40 anos (média de 29 anos), de ambos os sexos. Os pacientes apresentavam perfil côncavo com deficiência maxilar leve a moderada, com tratamento ortodôntico concluído e realizado por meio de compensações dentoalveolares sem cirurgia ortognática. Os participantes foram submetidos a procedimentos de preenchimento facial com ácido hialurônico (AH) no terço médio da face, implantado por um único operador. Fotografias padrão em norma frontal em repouso, perfil direito em repouso e perfil esquerdo em repouso foram obtidas de cada paciente nos seguintes tempos operatórios: (T1) pré-preenchimento e (T2) um mês pós-preenchimento. As fotografias em T1 e T2 foram inseridas aleatoriamente em uma página de um álbum virtual. Uma escala Likert de 5 pontos foi utilizada para avaliar a agradabilidade facial. As fotografias foram avaliadas por dois grupos de avaliadores formados por 18 indivíduos com fissura labiopalatina (GFLP=18) e 18 ortodontistas com experiência no tratamento de fissuras (GO=18). Para comparação entre as fases T1 e T2, e entre avaliadores com fissura labiopalatina e ortodontistas, foi utilizado o teste de Wilcoxon (p<0,05). Resultados: As pessoas com fissura labiopalatina avaliaram seu rosto como mais agradável após o preenchimento do terço médio da face. Já na percepção do ortodontista, a agradabilidade facial permaneceu semelhante após o procedimento de preenchimento facial. Conclusões: O preenchimento do terço médio da face em pacientes com fissura labiopalatina tratados sem cirurgia ortognática aumentou a agradabilidade da face na opinião dos leigos com fissura labiopalatina.
RESUMO
El tratamiento de la asimetría facial en pacientes con microftalmos o cavidades anoftálmicas adquiridas suele requerir cirugías reconstructivas agresivas. En los últimos años se han publicado trabajos sobre el uso de rellenos para optimizar la simetría del tejido orbitario, como técnicas mínimamente invasivas.Por este motivo, hemos realizado una revisión sistemática de la literatura publicada hasta el momento sobre la administración orbitaria de rellenos para el tratamiento de la pérdida de volumen. Se identificaron 14 artículos que cumplían con los criterios de selección; en los que se analizó el material utilizado, la técnica de inyección, el estudio anatómico de los pacientes antes del procedimiento y la presencia de complicaciones asociadas. Los materiales utilizados como relleno son: la grasa autóloga, la hidroxiapatita cálcica, el colágeno, el ácido hialurónico o el gel de poliacrilamida. Se aplicaron técnicas estándar de inyección peribulbar y retrobulbar, con escasas complicaciones asociadas, siendo la má grave el desarrollo de cuadros vaso-vagales. El seguimiento de los pacientes suele limitarse en la mayoría de los estudios a 12 meses, con variaciones significativas en la exoftalmometría posprocedimiento. En conclusión, la utilización de rellenos parece una práctica segura y con buenos resultados, aunque se precisan estudios con tiempo de seguimiento más prolongado que los publicados hasta el momento.

The treatment of facial asymmetry in patients with microphthalmos or acquired anophthalmic cavities usually requires aggressive reconstructive surgeries. In recent years, studies have been published on the use of fillers to optimize orbital tissue symmetry, as minimally invasive techniques.For this reason, we performed a systematic review of the literature published to date on the use of fillers for the treatment of volume loss in acquired anophthalmic or microphthalmic cavities. Fourteen articles were reviewed in which the material used, the injection technique, the anatomical study of the patients before the procedure and the presence of associated complications were analyzed.Various materials have been used as fillers, including autologous fat, calcium hydroxyapatite, collagen, hyaluronic acid, or polyacrylamide gel. Standard peribulbar and retrobulbar injection techniques were applied, with few associated complications, the most serious being the development of vasovagal symptoms. Patient follow-up is usually limited in most studies to 12 months.In Conclusion, the use of fillers seems to be a safe practice, with good results and few complications, although studies with longer follow-up times than those published to date would be required.

Hyaluronic acid (HA) dermal fillers are widely used in aesthetic treatments for facial and lip modeling. Despite HA fillers has largely known to be use in procedures for augmentation the lip volume, their application to management lip abnormalities is not widespread. This study reviewed the use of HA fillers for reconstruction of congenital and acquired li p asymmetries and deformities, searching to expand knowledge about this treatment modality. To undertake this narrative review, the Medline-Pubmed, Web of Science, Scopus, Embase, Google Schoolar e Lillacs databases were searched. Several studies have reported positive results in the use of HA fillers for the treatment of lip deformities caused by different factors such as: Insatisfactory dermal fillers, permanent lip implants, excision of lip carcinoma, post-operative scars and electrical burns. HA fillers are also an alternative for the management of lip asymmetries and residual surgical scars in patients with cleft lip. Moreover, injection of HA fillers in individuals with facial paralysis and facioscapulohumeral muscular dystrophy can also improve lip incompetence. Additionally, HA fillers can be used as a complementary treatment in cases of severe malocclusion associated with skeletal changes, helping to maintain the seal and refine the lip appearance. Therefore, HA fillers can be used as alternative treatment for several types of congenital and acquired lip deformities and asymmetries. However, it is necessary to carry out randomized clinical trials with a greater number of patients and follow-up time, in order to investigate the benefits of the HA fillers for carriers patients of lip abnormalities.
Los rellenos dérmicos de ácido hialurónico (AH) son muy utilizados en tratamientos estéticos para el modelado facial y de labios. A pesar de que se sabe en gran medida que los rellenos de HA se utilizan en procedimientos para aumentar el volumen de los labios, su aplicación para el tratamiento de anomalías labiales no está muy extendida. Este estudio revisó el uso de rellenos de HA para la reconstrucción de asimetrías y deformidades labiales congénitas y adquiridas, buscando ampliar el conocimiento sobre esta modalidad de tratamiento. Para realizar esta revisión narrativa, se realizaron búsquedas en las bases de datos Medline-Pubmed, Web of Science, Scopus, Embase, Google Schoolar y Lillacs. Varios estudios han reportado resultados positivos en el uso de rellenos de HA para el tratamiento de deformidades labiales causadas por diferentes factores tales como: rellenos dérmicos insatisfactorios, implantes labiales permanentes, escisión de carcinoma labial, cicatrices postoperatorias y quemaduras eléctricas. Los rellenos de HA también son una alternativa para el manejo de asimetrías labiales y cicatrices quirúrgicas residuales en pacientes con labio hendido. Además, la inyección de rellenos de HA en personas con parálisis facial y distrofia muscular facioescapulohumeral también puede mejorar la incompetencia de los labios. Además, los rellenos de HA se pueden usar como un tratamiento complementario en casos de maloclusión severa asociada con cambios esqueléticos, lo que ayuda a mantener el sellado y refinar la apariencia de los labios. Por lo tanto, los rellenos de HA se pueden utilizar como tratamiento alternativo para varios tipos de deformidades y asimetrías labiales congénitas y adquiridas. Sin embargo, es necesario realizar ensayos clínicos aleatorizados con mayor número de pacientes y tiempo de seguimiento, para investigar los beneficios de los rellenos HA para pacientes portadores de anomalías labiales.
RESUMO
O ácido hialurônico (AH) composto empregado na especialidade de harmonização orofacial para fins de preenchimento facial confere obtenção de harmonia em casos de estética deficiente. O objetivo desse trabalho é verificar se existe alteração dos sulcos labiais após a aplicação de ácido hialurônico, por meio de um relato de prontuário e análise de fotografias periorais. O prontuário selecionado foi de um paciente do sexo feminino, que se submeteu a um procedimento de preenchimento labial com infiltração de um volume total de 0,7 mL de ácido hialurônico da marca comercial (Hialurox Soft® 8mg/mL São Carlos - Brasil) e apresentava documentação fotográfica completa, anterior ao procedimento e pós-operatório tardio de 108 dias. Foi realizada uma simulação de confronto queiloscópico comparando as imagens entre si com o auxílio da ferramenta de edição Paint Microsoft, os sulcos foram classificados de acordo com o método de Suzuki e Tsuchihashi (1971), e os dados foram registrados na ficha modificada de Stamm (2014). A técnica utilizada no presente estudo não promoveu alteração significativa nos sulcos labiais pré-existentes. No entanto, o período do pós-operatório tardio de 108 dias não foi suficiente para o reaparecimento de alguns sulcos encontrados na fase pré-procedimento
The compound hyaluronic acid (HA) used in the specialty of orofacial harmonization for the purpose of facial filling confers harmony in cases of poor aesthetics. The aim of this study was to find out whether there are any changes to the labial folds after the application of hyaluronic acid, by means of a medical record report and analysis of perioral photographs. The medical record selected was that of a female patient who underwent a lip filling procedure with infiltration of a total volume of 0.7 mL of hyaluronic acid commercial brand (Hialurox Soft® 8mg/mL São Carlos Brazil) and had complete photographic documentation prior to the procedure and 108 days after the procedure. A cheiloscopic comparison simulation was carried out, comparing the images with each other using the Paint Microsoft editing tool, lip prints were classified according to the method of Suzuki and Tsuchihashi (1971), and the data was recorded on the modified form of Stamm (2014). The technique used in this study did not significantly alter the pre-existing labial traces. However, the late postoperative period of 108 days was not enough for some of the furrows found in the pre-procedure phase to reappear
RESUMO
A queiloscopia é uma técnica de identificação humana que consiste em estudar os lábios e suas características, como a espessura, a disposição da comissura labial, a posição dos sulcos e suas classificações, bem como o registro das impressões produzidas por eles em vários suportes. O aumento dos lábios com preenchedores de ácido hialurônico (AH) se tornou muito popular nos últimos anos, principalmente após inclusão da harmonização facial como especialidade odontológica. O objetivo deste estudo foi verificar se o preenchimento labial com AH tem implicações no estudo queiloscópico, por meio de um relato de caso clínico. Paciente do sexo feminino, 37 anos, leucoderma, participou do estudo. Foi realizado o registro fotográfico e tomadas as medidas de espessura labial, disposição da comissura labial e obtenção das impressões labiais com auxílio de batom, antes do preenchimento labial, 15 dias após aplicação de 1 ml de AH e 15 dias após completos 2 ml de preenchimento com AH. Os resultados do estudo sugerem que o preenchimento labial com AH pode interferir no método queiloscópico, pois houve alteração da arquitetura dos lábios, da disposição da comissura labial, melhorou contorno, arco do cupido e filtro, com mudança significativa na espessura dos lábios superior e inferior de aproximadamente 42% em relação ao volume anterior. Quanto ao padrão dos sulcos labiais, não houve alteração nos desenhos, no entanto, a qualidade da impressão labial foi afetada devido ao efeito produzido pelo AH
Cheiloscopy is a human identification technique that consists of studying the lips and their characteristics, such as their thickness, the arrangement of the labial commissure, the position of the grooves and their classifications, as well as recording the impressions produced by them on various supports. Lip augmentation with hyaluronic acid (HA) fillers has become very popular in recent years, especially since facial harmonization was included as a dental specialty. The aim of this study was to verify whether lip fillers with HA have implications for cheiloscopic studies, by means of a clinical case report. A 37-year-old female patient with leukoderma took part in the study. Photographs were taken and measurements of lip thickness, lip commissure layout and lipstick impressions were taken before the lip filler, 15 days after the application of 1 ml of HA and 15 days after the full 2 ml of HA filler. The results of the study suggest that lip filling with HA can interfere with the cheiloscopic method, as there was a change in the architecture of the lips, the layout of the labial commissure, improved contour, cupid's bow and filter, with a significant change in the thickness of the upper and lower lips of approximately 42% in relation to the previous volume. As for the pattern of the lip furrows, there was no change in the designs, however, the quality of the lip impression was affected due to the effect produced by the HA
RESUMO
De todas las enfermedades del sistema musculoesquelético, la osteoartritis (OA) es la más frecuente de las artritis, lo que conlleva a enormes gastos para la sociedad y una gran morbilidad para las personas que la padecen. Se caracteriza por afectar toda la articulación, incluyendo la degradación del cartílago, el remodelamiento óseo, la formación de osteofitos y la inflamación de la membrana sinovial. En consecuencia, se produce dolor, rigidez, hinchazón y pérdida de la función articular con marcada limitación funcional. El manejo de esta entidad implica una terapia no farmacológica, el uso de drogas para el alivio del dolor y cirugía cuando las medidas anteriores han fallado. Dentro de las medidas no farmacológicas destacan la educación, los ejercicios para el fortalecimiento muscular, la terapia física, la disminución de peso y las ortesis o dispositivos para asistir en la deambulación. En cuanto a las drogas recomendadas podemos mencionar a los antiinflamatorios no esteroideos tanto tópicos como orales y los glucocorticoides intraarticulares. Finalmente, la meniscectomía parcial por artroscopía solo se ha recomendado cuando existe bloqueo en la rodilla. En aquellos individuos que sufran de un dolor insoportable o una limitación funcional severa por una enfermedad avanzada debe considerarse el reemplazo total de la articulación.

Of all the diseases of the musculoskeletal system, osteoarthritis (OA) is the most common arthritis, leading to enormous costs to society and great morbidity for sufferers. It is characterized by involvement of the entire joint, including cartilage degradation, bone remodeling, osteophyte formation and inflammation of the synovial membrane. This results in pain, stiffness, swelling and loss of joint function with marked functional limitation. Management of this entity involves non-pharmacological therapy, the use of drugs for pain relief and surgery when previous measures have failed. Non-pharmacological measures include education, muscle strengthening exercises, physical therapy, weight reduction and orthoses or devices to assist ambulation. As for recommended drugs, non-steroidal anti-inflammatory drugs, both topical and oral, and intra-articular glucocorticoids are recommended. Finally, partial meniscectomy by arthroscopy has only been recommended when there is knee locking. In individuals suffering from excruciating pain or severe functional limitation due to advanced disease, total joint replacement should be considered. (provided by Infomedic International)

RESUMO
El carcinoma de células escamosas (CCE) de la piel es la segunda forma más frecuente de cáncer de piel, caracterizado por el crecimiento anormal y acelerado de las células escamosas. Detectado a tiempo, la mayoría de los CCE se pueden curar. Puede aparecer como manchas rojas escamosas, llagas abiertas, piel áspera, engrosada o verrugosa, o crecimientos elevados con una depresión en el medio y puede formar costras, picar o sangrar y suele ser más habitual en zonas expuestas al sol. La radiodermitis es un problema habitual en personas que reciben radioterapia como tratamiento para el cáncer, apareciendo en más del 95% de los casos. La intensidad de la reacción depende del tipo de radiación, la dosis total y la dosis de fracción, el área afectada, latécnica de tratamiento, la administración simultánea de quimioterápicos, además de factores del propio individuo (enfermedades crónicas, tabaquismo, estado nutricional, etc.). Con este caso, nos disponemos a demostrar la eficacia de la combinación de colagenasa bacteriana y ácido hialurónico como un óptimo procedimiento para el abordaje de este tipo de lesiones. El uso de este producto en nuestra consulta en pacientes con diferentes etiologías y como procedimiento para el abordaje de preparación del lecho de la herida (PLH), nos animó a comprobar su eficacia en lesiones de estas características.

Squamous cell carcinoma (SCC) of the skin is the second most common form of skin cancer, characterized by the abnormal and accelerated growth of squamous cells. Detected early, most SCC can be healed. It may appear as red scaly patches, open sores, rough, thickened or warty skin, or raised growths with a depression in the middle and may crust, itch or bleed and is more common in sun-exposed areas. Radiodermitis is a common problem in people receiving radiationtherapy as a cancer treatment, occurring in more than 95% of cases. The intensity of the reaction depends on the type of radiation, the total dose and the fraction dose, the affected area, the treatment technique, the simultaneous administration of chemotherapy, as well as individual factors (chronic diseases, smoking, nutritional status, etc.). With this case, we will demonstrate the efficacy of the combination of bacterial collagenase and hyaluronic acid as an optimal procedure for the treatment of this type of wounds. The use of this product in our practice in patients with different etiologies and as a procedure for the wound bed preparation approach encouraged us to prove its efficacy in wounds of these characteristics.

Introducción: la osteoartritis es una enfermedad crónica y progresiva que afecta a más del 30 % de las personas mayores de 60 años. Actualmente, se reconoce la osteoartritis como una enfermedad multifactorial. Se emplean varios tratamientos conservadores en el manejo de la osteoartritis de rodilla (AINE, analgésicos y terapias intraarticulares). Se realizó un ensayo clínico aleatorizado para determinar si una terapia a base de 10 g de colágeno hidrolizado y 100 mg de fucoidano (Hydroidan pro, Acten, Suiza) era más efectiva que las terapias intraarticulares. Métodos: se dividió a los pacientes en 3 grupos. El primero recibió 23 g de ACTEN® cada día durante 3 meses. Los otros grupos recibieron una única inyección intraarticular de ácido hialurónico (5 ml) o plasma rico en plaquetas (3 ml). Se emplearon las escalas WOMAC, SF-12 y VAS para valorar el dolor al inicio, 4, 12 y 24 semanas después. Resultados: se incluyó a 108 pacientes con osteoartritis de rodilla de grado II-III que participaron en un estudio de seguimiento de 24 semanas de duración. La edad media fue de 57 años (53-65). Los 3 grupos rebajaron la puntuación en el grupo WOMAC (p < 0,001). El grupo que recibió colágeno y fucoidano obtuvo puntuaciones más bajas en las escalas WOMAC y VAS que los grupos que recibieron ácido hialurónico y plasma rico en plaquetas a las 24 semanas (p < 0,001). Conclusiones: el colágeno y el fucoidano tomado por vía oral, a diario, y durante 12 semanas parecen cosechar mejores resultados en las escalas WOMAC y VAS que las terapias intraarticulares a base de ácido hialurónico o plasma rico en plaquetas. Se debería de intentarse combinar terapias orales e intraarticulares para determinar su perfil de eficacia.(AU)
Introduction: osteoarthritis is a chronic and progressive disease. It affects over 30 % of people older than 60. Osteoarthri-tis is currently recognized as a multifactorial disease. Various conservative treatments are used in the management of kneeosteoarthritis (NSAIDs, analgesics, and intra-articular therapy). We conducted a randomized clinical trial to determine if a10 g therapy of hydrolyzed collagen along with 100 mg fucoidan (Hydroidan pro, Acten, Switzerland) is more effective thanintra-articular therapies.Methods: we divided patients into 3 groups. The first group received 23 g of ACTEN®, daily, for 3 months. The other groupsreceived a single intra-articular injection of hyaluronic acid (5 ml) or platelet-rich plasma (3 ml). We used the WOMAC scale,the SF-12 scale, and the VAS for pain at baseline, and 4, 12, and 24 weeks later.Results: we enrolled 108 patients with grade II-III knee osteoarthritis who underwent a 24-week follow-up study. The meanage was 57 years (53-65). The three groups showed low scores in the WOMAC group (p < 0.001). The collagen with fucoid-an group had lower WOMAC and VAS scores compared with the hyaluronic acid and platelet-rich plasma groups at 24weeks (p < 0.001).Conclusions: collagen along with fucoidan taken orally, daily, for 12 weeks seem to have better results in the WOMACand VAS scales compared with intra-articular therapies such as hyaluronic acid or platelet-rich plasma. Combined oral andintra-articular therapies should be tried to determine their efficacy profile.(AU)

Introdução: Tradicionalmente, o rebaixamento do dorso é o único método de correção da giba. Raras séries apontam a elevação do radix como possível solução. O que explica essa maciça predominância do procedimento redutor? Ineficácia dos métodos de aumento de radix e ponta? Percepção de nariz grande com os procedimentos de aumento? Nossos objetivos são descobrir se a percepção de redução ocorre na rinoplastia não cirúrgica (RNC), feita exclusivamente com adição de volume, e se a percepção de redução é importante na RNC. Método: Análise retrospectiva de 116 pacientes consecutivos submetidos a RNC. As imagens dos pacientes foram analisadas por 12 observadores independentes que avaliaram as mudanças percebidas no tamanho do nariz e a qualidade da correção, dando notas de 1 a 10 para os dois quesitos. Quanto ao tamanho, 1 representava muito menor que antes, 5 mesmo tamanho (neutralidade) e 10 muito maior que antes. A qualidade da correção foi classificada de 1 a 10. Resultados: 92 casos (79%) foram percebidos como redução do tamanho, enquanto 20 casos (17%) foram percebidos como aumento. Houve percepção de redução na média das pontuações de tamanho (4,71). A média da qualidade da correção foi de 8,28 na escala de 1 a 10. Ademais, nossos resultados sugerem que pode haver correlação indireta entre a percepção do tamanho e a qualidade da correção. Conclusão: O aumento proporcionado pela RNC pode causar percepção de redução do tamanho do nariz, e o grau da redução percebida pode estar diretamente relacionado ao grau de qualidade percebida da correção.
Introduction: Traditionally, lowering the dorsum is the only method of hump correction. Rare series point to raising the radix as a possible solution. What explains this massive predominance of the reduction procedure? Ineffectiveness of radix and tip augmentation methods? Big nose perception with augmentation procedures? Our objectives are to determine if the perception of reduction occurs in non-surgical rhinoplasty (NSR), performed exclusively with volume addition, and if the perception of reduction is important in NSR. Method: Retrospective analysis of 116 consecutive patients undergoing NSR. The patients' images were analyzed by 12 independent observers who evaluated the perceived changes in the nose's size and the correction's quality, giving scores from 1 to 10 for both questions. As for size, 1 represented much smaller than before, 5 same size (neutrality), and 10 much larger than before. The quality of correction was graded from 1 to 10. Results: 92 cases (79%) were considered size reduction, while 20 cases (17%) were considered enlargement. There was a perception of a reduction in the average size scores (4.71). The mean correction quality was 8.28 on a scale of 1 to 10. Furthermore, our results suggest that there may be an indirect correlation between perceived size and correction quality. Conclusion: The increase provided by the NSR can cause a perception of a reduction in the size of the nose, and the degree of perceived reduction can be directly related to the degree of perceived quality of the correction.
RESUMO
Este estudo teve como objetivo realizar um levantamento bibliométrico das pesquisas realizadas em odontologia na área de harmonização orofacial, com ênfase na bichectomia, ácido hialurônico e toxina botulínica. Utilizou-se como base os anais dos trabalhos apresentados nas Reuniões Anuais da Sociedade Brasileira de Pesquisa Odontológica (SBPqO) entre os anos de 2017 a 2021e todos os resumos que possuíam algumas das palavras-chaves pesquisadas ("bichectomia", "ácido hialurônico" e "toxina botulínica") foram avaliados. Após a seleção informações foram coletadas dos resumos e os dados foram analisados através de estatística descritiva.Foram incluídos neste estudo 65 resumos, estando a maioria relacionado com pesquisas utilizando a toxina botulínica. O ano de 2021 foi o que apresentou uma maior produção de estudos sobre o tema e a região Sudeste do Brasil foi a que mais produziu acerca da harmonização orofacial nos últimos cinco anos. A maioria das pesquisas foram desenvolvidas por instituições privadas e não receberam financiamento. Dentre as áreas da odontologia a desordens temporomandibular, dor orofacial e a periodontia aparecem com maior envolvimento com as pesquisas utilizando, principalmente a toxina botulínica e o ácido hialurônico. Conclui-se que as pesquisas envolvendo temas relacionados a área de harmonização ainda representam um número baixo, entretanto esse número apresentou crescimento nos últimos 5 anos. Se faz necessário mais incentivo em pesquisas nessa área para as regiões norte e centro oeste,bem como um maior em financiamento.
This study aimed to carry out a bibliometric survey of research carried out in dentistry in the area of orofacial harmonization, with emphasis on bichectomy, hyaluronic acid and botulinum toxin. The annals of the works presented at the Annual Meetings of the Brazilian Society for Dental Research (SBPqO) between the years 2017 to 2021 and all abstracts that had some of the searched keywords ("bichectomy", "hyaluronic acid" and "botulinum toxin") were evaluated. After the selection, information was collected from the abstracts and the data were analyzed using descriptive statistics. A total of 65 abstracts were included in this study, most of which related to research using botulinum toxin. The year 2021 was the one that presented the greatest production of studies on the subject and the Southeast region of Brazil was the one that produced the most about orofacial harmonization in the last five years. Most research was developed by private institutions and did not receive funding. Among the areas of dentistry, temporomandibular disorders, orofacial pain and periodontics appear with greater involvement with research using, mainly, botulinum toxin and hyaluronic acid. It is concluded that research involving topics related to the harmonization area still represents a low number, however this number has grown in the last 5 years. More incentives are needed for research in this area for the North and Midwest regions, as well as greater funding.

Introdução: As Disfunções temporomandibulares (DTM) incluem desordens dos músculos da mastigação, das articulações temporomandibulares e da inervação local, frequentemente associadas a dor orofacial e que resultam em mioartropatias do Sistema Mastigatório. A tendência atual tende a começar com tratamento conservador e progredir a procedimentos mais invasivos na falha dos tratamentos iniciais. Relato de caso: O presente relato visa mostrar o resultado de uma técnica invasiva para o tratamento de uma DTM grave, com a aplicação do ácido hialurônico e de corticoide através de uma punção guiado por ultrassonografia. A paciente apresentava dor crônica e perda importante de peso devido a limitação da abertura da boca. A RM demonstrou disfunção das ATMs, com sinais de deslocamento parcial do disco direito anteromedialmente. Foi realizada a aplicação bilateral intra-articular de ácido hialurônico e de corticoide através de uma punção guiado por ultrassonografia. Considerações Finais: A associação destas classes na punção de ATMs ainda não está bem estabelecida havendo necessidade de estudos complementares para avaliar eficácia, como este relato de caso, que se mostrou favorável com grande melhora clínica da paciente...

Introduction: Temporomandibular dysfunctions (TMD) include disorders of the masticatory muscles, temporomandibular joints, and local innervation, often associated with orofacial pain and resulting in myoarthropathies of the masticatory system. The current trend tends to begin with conservative treatment and progress to more invasive procedures if the initial treatments fail. Case Report: The present report aims to show the result of an invasive technique for the treatment of a severe TMD, with the application of hyaluronic acid and corticoid through an ultrasound-guided puncture. The patient presented with chronic pain and significant weight loss due to limited mouth opening. MRI demonstrated TMJ dysfunction, with signs of partial anteromedial dislocation of the right disc. Bilateral intra-articular application of hyaluronic acid and corticoid was performed through an ultrasound guided puncture. Final considerations: The association of these classes in TMJ puncture is still not well established, and further studies are needed to evaluate efficacy, as in this case report, which proved favorable, with great clinical improvement for the patient...

Introducción: Los trastornos temporomandibulares (TTM) incluyen trastornos de los músculos masticatorios, de las articulaciones temporomandibulares y de la inervación local, a menudo asociados a dolor orofacial y que dan lugar a mioartropatías del sistema masticatorio. La tendencia actual es comenzar con un tratamiento conservador y progresar hacia procedimientos más invasivos al fracasar los tratamientos iniciales. Informe de un caso: El presente informe pretende mostrar el resultado de una técnica invasiva para el tratamiento de un TTM severo, con la aplicación de ácido hialurónico y corticoide a través de una punción guiada por ecografía. El paciente presentaba dolor crónico y una importante pérdida de peso debido a la limitación de la apertura bucal. La RMN demostró una disfunción de la ATM, con signos de dislocación parcial del disco derecho anteromedialmente. Se realizó la aplicación intraarticular bilateral de ácido hialurónico y corticoide mediante una punción guiada por ecografía. Consideraciones finales: La asociación de estas clases en la punción de la ATM aún no está bien establecida y se necesitan más estudios para evaluar la eficacia, como en el reporte de este caso, que resultó favorable con gran mejoría clínica del paciente...
