Impact of COVID-19 on maxillofacial surgery practice: a systematic review / Impacto da Covid-19 na prática da cirurgia bucomaxilofacial: uma revisão sistemática

Abstract Objectives: The aim of this systematic review was to evaluate the possible impacts of COVID-19 on oral and maxillofacial surgery practice, as well as the protocols employed by oral and maxillofacial surgeons to minimize the risks of contamination. Methods: Searches were performed in different databases up to 15 March 2021. Articles related to oral surgery dynamics within the context of the COVID-19 pandemic were included. The articles were considered eligible if they met the following inclusion criteria: observational studies that provided recommendations regarding maxillofacial surgery measures during the COVID-19 pandemic and that analyzed the risk of contamination of patients/professionals with SARS-CoV-2. Results: Seven studies met the inclusion criteria and were selected for the present systematic review. Demands for personal protective equipment increased significantly, with studies reporting the scarcity of fundamental equipment such as FFP2/N95 masks. Significant changes in the infrastructure of outpatient, surgical and inpatient units and in the care protocols themselves were observed. Conclusion: The COVID-19 pandemic particularly affected the routine of oral and maxillofacial surgery residents. Several additional recommendations for surgical practice or for the surgical team were evaluated and discussed, such as performing primarily urgent and emergency surgeries, remote patient care and screening, postponing elective surgeries, and new teaching methods in oral and maxillofacial surgery residency programs. In addition, screening of patients and of the surgery team for COVID-19 is strongly recommended.

Effectiveness of disk repositioning and suturing comparing open-joint versus arthroscopic techniques: a systematic review and meta-analysis.

OBJECTIVE: The aim of this study was to present a systematic review of the effectiveness of discopexy in managing internal derangement of the temporomandibular joint (TMJ). STUDY DESIGN: We searched MEDLINE through PubMed, SCOPUS, Web of Science, and Cochrane Central Register of Controlled Trials and grey literature accessed through Google Scholar, Openthesis, and hand-searching from inception to July 2020. The search strategy yielded 363 potentially relevant studies. After screening titles and abstracts, 41 full-text articles were assessed for eligibility and 7 studies were included in the meta-analysis. RESULTS: There was an overall decrease in visual analog scale (VAS) pain score of 4.59 cm (95% confidence interval [CI], 2.03-7.16; P < .001) during the follow-up time and an overall increase of 10 mm (95% CI, 6.93-13.01; P < .001) in mouth opening after TMJ surgeries with discopexy. CONCLUSIONS: The available evidence showed an overall decrease in VAS pain score and an improvement in mouth opening after TMJ surgeries with discopexy. Changes in maximal interincisal opening were greater after arthroscopic disk repositioning compared to open-joint procedure.

Factors Associated with the Oral Health-Related Quality of Life in Children with Intellectual Disabilities / Factores asociados con la calidad de vida relacionada con la salud bucal en niños con discapacidad intelectual

Abstract: Different factors can influence the perception of quality of life in individuals with intellectual disabilities. This study investigated the factors associated with quality of life related to oral health in children with intellectual disabilities from the perspective of their parents. A cross-sectional study was carried out with Brazilian children from specialized institutions and their respective guardians. Data were collected through medical records, application of instruments and oral clinical examination (n=92). Most children had poor oral hygiene (64.10%) and a high caries experience (59.8%). The mothers' perception of quality of life related to oral health was low, however there was an association of greater perception when they had low education, female child, less brushing frequency and history of breastfeeding (p≤0.05). Although the perception of quality of life was low, the oral condition found evidences the need to promote oral health education actions with children with intellectual disabilities and their respective guardians.

Resumen: Diferentes factores pueden influir en la calidad de vida de personas con discapacidad intelectual. Este estudio investigó los factores asociados con la calidad de vida relacionada con la salud oral en niños con discapacidades intelectuales desde la perspectiva de sus cuidadores. Se realizó un estudio transversal con niños brasileños institucionalizados, que fueron evaluados clínicamente y sus respectivos tutores, quienes respondieron cuestionarios. Los datos fueron recolectados a través de registros médicos, aplicación de instrumentos de evaluación y examen clínico oral (n=92). La mayoría de los niños presentaban una higiene oral deficiente (64,10%) y una experiencia de caries alta (59,8%). Si bien la percepción específicamente de las madres respecto del impacto de las condiciones de la salud oral en la calidad de vida fue baja, mostró una tendencia a aumentar en cuanto disminuía el nivel educacional, la frecuencia de cepillado y la historia de lactancia materna (p≤0.05). El hecho de que la percepción del impacto en la calidad de vida por parte de los tutores no se condiga con las precarias condiciones de salud oral exhibida por los niños con discapacidad intelectual, no sólo demuestra el desconocimiento respecto de la importancia de la salud oral en un contexto general, sino que también evidencia la necesidad de promover acciones que incentiven el cuidado y educación en relación con este aspecto, tanto en los tutores como en los niños afectados.

Effects of Water-Circulating Cooling Mask on Postoperative Outcomes in Orthognathic Surgery and Facial Trauma.

The purpose of this study was to perform a systematic review and meta-analysis of randomized clinical trials (RCTs) investigating the efficacy of hilotherapy on postoperative pain, swelling, neurosensory impairment and patient satisfaction. The authors analyzed RCTs comparing the use of hilotherapy versus conventional cryotherapy or no cold treatment for orthognathic surgery and repair of facial trauma. The authors assessed the risk of bias and strength of evidence according to the Cochrane guidelines and GRADE rating system, respectively. Treatment effects were defined as weighted or standardized mean difference using the inverse variance method. Five RCTs were included. Postoperative pain and swelling in patients using hilotherapy were lower comparing to the control group in the postoperative day 2 (Pain: MD -1.75, CI 95% -2.69 to -0.81; Swelling: MD -21.16 mL, CI 95% -38.91 to -3.41) and in the final evaluation (Pain: MD -0.31, CI 95% -0.44 to -0.18; MD -4.45 mL, CI 95% -7.87 to -1.03). Patients reported higher satisfaction with hilotherapy, but no differences were found for neurosensory impairment. Current evidence suggests that hilotherapy is effective in reducing postoperative pain and swelling in orthognathic surgery and repair of facial fractures and may lead to improvements in patient satisfaction in the recovery phase.

One Abutment at One Time Concept for Platform-Switched Morse Implants: Systematic Review and Meta-Analysis

Abstract The aim of this systematic review and meta-analysis was to compare the peri-implant vertical bone loss of immediate loading of implant crowns using the one abutment at one time (AOT) protocol and implants with abutment removal (AR). This systematic review with meta-analysis was reported according to the PRISMA statement, with guidance from the Cochrane Collaboration Handbook. A total of 103 publications were identified in the PubMed database and reference lists of examined articles. After the screening of titles and abstracts, the eligibility of eight full-text articles was assessed. Five studies published between 2010 and 2015 were included in the meta-analysis. There was less peri-implant vertical bone loss at implants using an AOT protocol than at implants using AR protocol (WMD -0.19, 95% CI -0.26 to -0.13; p<0.0001; random-effects model). In conclusion, the use of the AOT protocol with platform-switched Morse implants results in less bone loss than do AR procedures, but this effect may not be clinically relevant. The preservation of marginal bone level achieved with the AOT protocol may not enhance the aesthetics. These results should be interpreted with caution.

Resumo O objetivo desta revisão sistemática e meta-análise foi comparar a perda óssea vertical em implantes de carga imediata usando o protocolo de um pilar em um único momento (AOT) e implantes com remoção de pilar (AR). Esta revisão sistemática com meta-análise foi relatada de acordo com a declaração PRISMA, com orientação do Cochrane Collaboration Handbook. Foram identificadas 103 publicações na base de dados PubMed e nas listas de referência dos artigos examinados. Após a triagem de títulos e resumos, avaliou-se a elegibilidade de oito artigos de texto completo. Cinco estudos publicados entre 2010 e 2015 foram incluídos na meta-análise. Houve menos perda óssea vertical peri-implante em implantes usando o protocolo AOT do que nos implantes usando o protocolo AR (WMD -0,19, 95% IC -0,26 a -0,13; p <0,0001, modelo de efeitos aleatórios). Em conclusão, o uso do protocolo AOT com implantes Cone Morse associados a pilares com plataforma switching resulta em menos perda óssea do que os procedimentos AR, mas esse efeito pode não ser clinicamente relevante. A preservação do nível ósseo marginal alcançado com o protocolo AOT pode não melhorar a estética. Estes resultados devem ser interpretados com cautela.

Procedimento de bichectomia: uma discussão sobre os aspectos éticos e legais em odontologia / Bichectomy procedure: a discussion on the ethical and legal aspects in odontology

Introdução: O procedimento denominado de bichectomia consiste na remoção parcial de uma estrutura adiposa na região das bochechas e ganhou recente popularidade entre a classe odontológica, que passou a executá-lo amplamente, com demandas predominantemente estéticas e, com isso, dúvidas e incertezas surgiram a respeito dos seus aspectos éticos e legais. Objetivo: O objetivo deste trabalho foi buscar legislações nacionais, bem como normativas e resoluções emitidas por conselhos profissionais, visando abordar tais controvérsias, alumiando os profissionais quanto à legitimidade do procedimento. Resultados: Verificou-se que desde 1978, os Conselhos Federais de Medicina e de Odontologia vêm emitindo resoluções para determinar limiares de atuação profissional, em especial, com enfoque na especialidade Cirurgia e Traumatologia Bucomaxilofacial, visto que é a especialidade odontológica clínica que mais se aproxima de campos de atuação médica. Com o tempo, estes Conselhos foram atualizando estas Resoluções, tendo em vista os avanços técnicos e científicos da área, porém todas as resoluções analisadas são unânimes em afirmar que a realização de bichectomia com finalidade estritamente estética é atribuição médica. Conclusão: Desta forma, com base nos documentos atualmente vigentes, verifica-se que o cirurgião-dentista que estiver disposto a realizar a cirurgia de bichectomia com finalidade exclusivamente estética estará incorrendo em transgressões administrativas e, consequentemente, tais interpretações podem ser vislumbradas em outras esferas (cíveis e criminais).

Introduction: Bichectomy consists of removing part of a fat structure in the region of the cheeks, and it recently gained popularity in the field of odontology, which began to widely perform the procedure, with predominantly aesthetic demands and, with that, doubts and uncertainties arose with respect to its ethical and legal aspects. Objective: The objective of this work was to seek national laws, as well as normative and resolutions issued by professional councils, aiming to address such controversies, enlightening professionals to the legitimacy of the procedure. Results: Since 1978, the Federal Councils of Medicine and Dentistry have issued resolutions to determine thresholds for professional performance, which particularly focused on Oral and Maxillofacial Surgery and Traumatology because it is the closest clinical dental specialty of medical practice. Over time, these Councils have been updating these resolutions, considering the technical and scientific advances of the area, but all the resolutions analyzed were unanimous in affirming that the accomplishment of bichectomy with a strictly aesthetic purpose is a medical attribution. Conclusion: Subsequently, based on the documents currently in force, it is verified that the dental surgeon who is willing to perform bichectomy surgery for aesthetic purposes will be incur administrative infractions and, consequently, such interpretations can be seen in other legal areas (civil and criminal).

Maxillary sinus grafting with fresh frozen allograft versus bovine bone mineral: A tomographic and histological study.

We evaluated histologically and tomographically the effects of fresh frozen bone allograft (FFB) or bovine bone mineral (BBM) in maxillary sinus floor augmentations. In total, 30 maxillary sinuses from 30 patients (mean age = 51.17 ± 10.86 years) underwent sinus augmentation. Patients were divided in two test groups (15 sinuses each). The first group was grafted with allograft bone, and the second group received bovine bone mineral. After 6 months, bone samples from each group were collected for histological examination. Implant survival rates were 97.78% (FFB group) and 100% (BBM group) 6 months after functional loading. Median volumetric reductions of 31.2% (11.33-40.56) and 12.22% (9.91-20.59) were observed in the FFB and BBM groups, respectively. Comparisons between the groups for differences in initial and final volumes of bone (p = 0.015) and the rate of resorption (p = 0.009) showed statistically significant differences. The FFB group showed osteoblastic cells in close contact with osteoid matrix, connected through bridges between allograft bone particles and new bone formation. The BBM group showed BBM particles in close contact with new bone, with visible osteoid matrix bridges and osteoblastic cells surrounding it. None showed signs of acute or chronic inflammatory infiltrate. Despite better results with BBM, both FFB and BBM in maxillary sinus augmentation resulted in high percentages of new bone formation, and allowed implant placement with a low rate of failure of osseointegration at a 6-month follow-up.

Effect of collagen sponge and fibrin glue on bone repair

ABSTRACT The ability of hemostatic agents to promote bone repair has been investigated using in vitro and in vivo models but, up to now, the results are inconclusive. Objective In this context, the aim of this study was to compare the potential of bone repair of collagen sponge with fibrin glue in a rat calvarial defect model. Material and Methods Defects of 5 mm in diameter were created in rat calvariae and treated with either collagen sponge or fibrin glue; untreated defects were used as control. At 4 and 8 weeks, histological analysis and micro-CT-based histomorphometry were carried out and data were compared by two-way ANOVA followed by Student-Newman-Keuls test when appropriated (p≤0.05). Results Three-dimensional reconstructions showed increased bone formation in defects treated with either collagen sponge or fibrin glue compared with untreated defects, which was confirmed by the histological analysis. Morphometric parameters indicated the progression of bone formation from 4 to 8 weeks. Additionally, fibrin glue displayed slightly higher bone formation rate when compared with collagen sponge. Conclusion Our results have shown the benefits of using collagen sponge and fibrin glue to promote new bone formation in rat calvarial bone defects, the latter being discreetly more advantageous.

Comparative Analysis Between Computed and Conventional Inferior Alveolar Nerve Block Techniques.

OBJECTIVE: The aim of this randomized, double-blind, controlled trial was to compare the computed and conventional inferior alveolar nerve block techniques in symmetrically positioned inferior third molars. PATIENTS AND METHODS: Both computed and conventional anesthetic techniques were performed in 29 healthy patients (58 surgeries) aged between 18 and 40 years. The anesthetic of choice was 2% lidocaine with 1: 200,000 epinephrine. The Visual Analogue Scale assessed the pain variable after anesthetic infiltration. Patient satisfaction was evaluated using the Likert Scale. Heart and respiratory rates, mean time to perform technique, and the need for additional anesthesia were also evaluated. RESULTS: Pain variable means were higher for the conventional technique as compared with computed, 3.45 ±â€Š2.73 and 2.86 ±â€Š1.96, respectively, but no statistically significant differences were found (P > 0.05). Patient satisfaction showed no statistically significant differences. The average computed technique runtime and the conventional were 3.85 and 1.61 minutes, respectively, showing statistically significant differences (P <0.001). CONCLUSIONS: The computed anesthetic technique showed lower mean pain perception, but did not show statistically significant differences when contrasted to the conventional technique.

Treatment of condylar fractures with an intraoral approach using an angulated screwdriver: results of a multicentre study.

BACKGROUND: This multicentre study aimed to investigate long-term radiographic and functional results following the treatment of condylar fractures using an angulated screwdriver system and open rigid internal fixation with an intraoral surgical approach. METHODS: Twenty-nine patients with a total of 32 condylar fractures were evaluated. The patients were investigated prospectively based on the following variables: age, sex, aetiology, side, location and classification of the fracture, degree of displacement, associated fractures, surgical approach, oral health status, type of osteosynthesis plate, duration of surgery, mouth-opening, complications, and duration of follow-up. RESULTS: The fractures were classified as subcondylar (n = 25) or condylar neck (n = 7). Mean patient age was 36.38 ± 16.60 years. The median duration of postoperative follow-up was 24.39 ± 13.94 months. No joint noise, weakness of the facial nerve, joint pain, or muscle pain was observed. An additional retromandibular approach was necessary to enable the treatment of one subcondylar fracture with medial displacement. CONCLUSION: Subcondylar or condylar neck fractures with medial or lateral displacement can be treated using an intraoral approach with satisfactory results with the advantages of the absence of visible scarring, the avoidance of facial nerve injury, and the ability to obtain rapid access to the fracture.

Ameloblastoma in the Northeast region of Brazil: A review of 112 cases.

CONTEXT: Ameloblastomas are benign tumors of the jaws with locally invasive capacity. AIM: The aim of this study was to review 112 cases of ameloblastoma seen over an 18-year period (1992-2009) at the Pernambuco Dental School, University of Pernambuco and at Federal University of Sergipe, in the northeast region of Brazil. MATERIALS AND METHODS: THE FOLLOWING DATA WERE SELECTED FOR ANALYSIS: age, gender, race, site distribution, radiographic appearance, association with an impacted tooth, size, presence of symptoms, clinicopathologic subtypes and recurrence. SETTINGS AND DESIGN: In this retrospective study, Pearson's χ(2) test and t-test were employed. The critical level of significance was set at P < 0.05. RESULTS: The mean age of the patients at presentation was 35.1 ± 16.8 years with a slight female preference. The peak prevalence was in the 11- to 20-year age group and declined with increasing age. Total 75 patients were black and 37 were white, for a 2:1 black: white ratio. The location of the ameloblastomas showed a marked predominance in the mandible (84.8%) and 69% of the cases presented with a multilocular radiographic appearance. The tumor was associated with an embedded tooth in 14 cases (12.7%): nine unilocular and five multilocular ameloblastomas. The maximum radiological extension of the lesions on panoramic radiographs was 0.5-20 cm (mean ± SD: 5.2 ± 3.3 cm) and most cases were symptom-free (75.9%). Solid/multicystic ameloblastoma was the most common clinicopathologic subtype. There was an association between the clinicopathologic subtypes and radiographic appearance (P < 0.001). Recurrence was observed in 13.3% of cases. CONCLUSION: We propose that racial factors may have strong influence on the incidence of ameloblastomas in the northeast region of Brazil, since most people have African descent. Data related to gender, location, radiographic appearance, size, symptoms, clinicopathologic subtypes and recurrence were similar to previous studies conducted in various parts of the world.

Two-stage treatment of facial asymmetry caused by unilateral condylar hyperplasia.

Condylar hyperplasia (CH) is a rare, self-limiting process manifesting between the first and third decades of life. CH causes facial asymmetry and derangement of the occlusion. Management involves resection of the condylar head and orthognathic surgery. This paper describes the case of a 37-year-old woman with spontaneous onset of CH over a span of approximately 25 years. The condition was managed with resection of the condyle alone, which dramatically improved facial asymmetry and altered the occlusion within a few months of follow up. Orthodontic treatment was then carried out and the patient underwent orthognathic surgery after 3 years. The patient is currently satisfied with her appearance and function and there are no signs of recurrence.

Hiperplasia condilar (HC) é um processo raro e auto-limitativo que ocorre entre a 1a e a 3a décadas de vida. Ela causa assimetria facial e alteração da oclusão. O tratamento envolve ressecção da cabeça do côndilo e cirurgia ortognática. Este artigo descreve o caso de uma mulher de 37 anos com início espontâneo de HC e duração de aproximadamente 25 anos. O tratamento foi feito com ressecção apenas do côndilo, o que melhorou consideravelmente a assimetria facial e a oclusão em poucos meses de acompanhamento. Seguiu-se o tratamento ortodôntico e a paciente foi submetida a cirurgia ortognática três anos depois. Atualmente a paciente está satisfeita com sua aparência e função, sem apresentar sinais de recorrência.
