RESUMEN
Background: Disruption of peripheral branches of the trigeminal nerve in the field of maxillofacial surgery is a known risk due to the close connection of these branches with the bony structures of the maxilla and mandible. As a result, injuries of the lingual nerve and inferior alveolar nerve take place within routine maxillofacial surgery procedures, including local anesthetic injection, wisdom tooth surgery, and dental implant placement, resulting in paresthesia and dysesthesia. During the last three decades, low-level lasers (LLL) have been frequently used in various medical fields. Lately, this application has increased in several sectors. Methods and materials: This experiment was designed to explore the effect of low-level laser therapy (LLLT) with Nd:YAG on the paresthesia and dysesthesia of the lower lip. This ethics committee of Tbzmed, Tabriz, Iran, proved the present experiment with ethical code: IR.TBZMED.REC.1401.839. Results: After completing 10 sessions of laser therapy for the case group consisting of 25 patients with lower lip anesthesia, the visual analog scale index results revealed that following six sessions of laser therapy, a significant difference appeared in contrast to the control group. Also, according to the two-point tests, significant difference among the experimental and the control group appeared after ninth session of the laser therapy. Conclusions: Altogether, these data suggested LLLT with Nd:YAG as an effective treatment option for decreasing the anesthesia of the lower lip.

Oral dysaesthesia is a condition characterised by persistent alteration to oral sensation, perceived by the patient to be abnormal and/or unpleasant, in the absence of any mucosal pathology. The condition can be difficult to detect and diagnose. A possible peripheral or central neuropathic aetiology has been proposed. Burning mouth syndrome (BMS) is the most common idiopathic oral dysesthesia in which long-term suffering is often reported by patients. Recent efforts from professional organisations and study groups have provided a consensus on BMS disease definition and diagnostic criteria. Large-scale epidemiological studies are required to provide an accurate estimate for prevalence and incidence of the condition. Meticulous diagnostic investigations which may require interdisciplinary teamwork are often warranted to reach an accurate diagnosis. A combination of interventional modalities, with a holistic approach, is key for successful management and improvement in patients' quality of life.

Subacute combined degeneration (SCD) is an acquired neurologic complication from prolonged vitamin B12 deficiency. As a result of dorsal and lateral spinal cord column degeneration, patients present with a range of neurological symptoms, including paresthesias, ataxia, and muscle weakness. Without prompt treatment, irreversible nerve damage occurs. Here we present a young man who developed progressive ascending paresthesias and lower extremity weakness after escalated nitrous oxide use. This case highlights the importance of considering SCD from nitrous oxide toxicity when patients present with progressive ataxia, paresthesia, and lower extremity weakness.

Nas cirurgias odontológicas é possível que ocorra alguns acidentes ou complicações que podem interferir no dia a dia do paciente. A lesão do nervo alveolar inferior é uma complicação decorrente de cirurgias orais que podem causar um distúrbio de sensibilidade transitória ou persistente, na região do lábio inferior e na região delimitada do forame mentoniano e hemi-arco da mucosa. O diagnóstico da parestesia pode ser feito através de testes mecanoceptivos e nocioceptivos em que o profissional escolherá para qual melhor se adapte no paciente. O objetivo do presente trabalho foi abordar por meio de uma revisão de literatura as formas de diagnóstico e tratamento da parestesia do nervo alveolar inferior decorrentes de cirurgias orais. As bases de dados utilizadas para confecção desta revisão são encontradas nas bibliotecas virtuais eletrônicas: BVS (Biblioteca Virtual em Saúde), LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde) e Pubmed. Como critério de inclusão foram selecionados artigos publicados de 2012 a 2022 em língua inglesa, portuguesa e espanhola. Após a leitura do título e resumo dos resultados da pesquisa e aplicação dos critérios de inclusão e exclusão dentre eles foram excluídos 883, pois não se enquadravam no nosso critério de inclusão. No final, foram selecionados 13 estudos por meio de base de dados, que serviram de base para esta revisão. Concluímos que as formas de tratamento para a parestesia na literatura, são um pouco escassas e conflitantes, mas relata que o uso da laserterapia e acupuntura tem sido uma forma de tratamento com um bom índice de sucesso, e para os casos que não sejam suficientes tais tratamentos, pode-se optar por uma cirurgia(AU)
In dental surgeries it is possible to have some accidents or complications that can interfere with the patient's day. Injury to the inferior alveolar nerve is a complication resulting from oral surgeries that can cause a disturbance of sensitivity that can be transient or persistent in the region of the lower lip and in the delimited region of the mental foramen and hemiarch of the mucosa. The diagnosis of paresthesia can be made through mechanoceptive and nocioceptive tests that the professional will choose, which best suits the patient. The objective of the present work is to approach, through a literature review, the forms of diagnosis and treatment aimed at inferior alveolar nerve paresthesia resulting from oral surgeries. The databases used for this review are found in the virtual electronic libraries: VHL (Virtual Health Library), LILACS (Latin American and Caribbean Literature on Health Sciences) and Pubmed. As inclusion criteria, articles published from 2012 to 2022 in English, Portuguese and Spanish were selected. After reading the title and summary of the research results and applying the inclusion and exclusion criteria, 883 were excluded, as they did not meet our inclusion criteria. In the end, 13 studies were selected from the database, which served as the basis for this review. We conclude that the forms of treatment for paresthesia in the literature are a little scarce and conflicting, but it reports that the use of laser therapy and acupuncture has been a form of treatment with a good success rate, and for cases that are not enough, such treatments, one can opt for surgery(AU)

A parestesia é um distúrbio neurossensorial decorrente de lesão nervosa que ocorre após uma intervenção odontológica e leva à perda de sensibilidade prolongada de uma região específica da face, além de outros sintomas, podendo ser resolvida espontaneamente após alguns dias ou meses, mas dependendo da extensão e tipo de lesão nervosa, este dano pode ser permanente. Com o avanço da tecnologia, os lasers vêm se popularizando na Odontologia, juntamente com os avanços em pesquisas. A terapia de fotobiomodulação com laser de baixa potência tem se mostrado como uma opção favorável ao tratamento de distúrbios neurossensoriais e aceleração do processo de reparo tecidual. Foi realizada uma revisão da literatura, a partir de buscas nas bases de dados do PubMed/MEDLINE, Biblioteca Virtual em Saúde (BVS), The Cochrane Librarye Scielo, entre os anos de 2010 a 2020. O presente estudo tem como objetivo analisar a eficácia, a utilização terapêutica, e os mecanismos de ação da terapia a laser de baixa potência (LLLT), como também causas e fatores de risco relacionados aos procedimentos mais comuns de injúria nervosa. As recentes pesquisas envolvendo o uso da terapia de fotobiomodulação evidenciam a capacidade do laser em promover aceleração do processo de reparo tecidual, com fenômenos analgésicos, anti-inflamatórios, cicatrizantes e regenerativos. Embora tenha havido grandes descobertas nos últimos anos, a literatura ainda carece de protocolos e ensaios clínicos sobre o uso do laser, verificando e comprovando seus efeitos sobre lesões nervosas, devendo este ser o foco de pesquisas futuras(AU)
Paresthesiais a neurosensory disorder resulting from nerve damage that occurs after a dental intervention and leads to prolonged loss of sensation in a specific region of the face, in addition to other symptoms, which can be resolved spontaneously after a few days or months, but depending on the extension and type of nerve damage, this damage can be permanent. With the advancement of technology, lasers have become popular in dentistry, along with advances in research. The photobiomodulation therapy with low level laser has been shown to be a favorable option for the treatment of neurosensory disorders and acceleration of the tissue repair process. A literature review was carried out, based on searches in the databases of PubMed / MEDLINE, Virtual Health Library (VHL),The Cochrane Library and Scielo, between 2010 and 2020. The present study aims to analyze the effect, therapeutic use, and the mechanisms of action of low level laser therapy (LLLT), as well ascauses and factors related to the most common nerve injury procedures. Recent research involving the use of photobiomodulation therapy shows the laser's ability to accelerate the tissue repair process, with analgesic, anti-inflammatory, healing and regenerative phenomena. Although there have been major discoveries in the years, the literature still lacks protocols and clinical trials on the use of lasers, verifying and proving their effects on nerve injuries, which should be the focus of future research(AU)

We report two cases of subacute combined degeneration (SCD) caused by nitrous oxide (N₂O) gas intoxication, which is rarely reported in Korea. Two patients recreationally inhaled N₂O gas daily for several months. They presented with paresthesia of limbs, voiding difficulty, and gait disturbance. The initial vitamin B₁₂ levels were normal or decreased, but homocysteine levels of the two patients were increased. Magnetic resonance imaging of the cervical spine showed T2-weighted hyperintensity in the bilateral dorsal columns of the cervical spinal cord. Electromyography and somatosensory evoked potential tests for both patients suggested posterior column lesion of the spinal cord combined with sensorimotor polyneuropathy. According to these findings, we concluded that the two patients had SCD. The patient’s symptoms partially improved after cessation of N₂O gas inhalation and the receiving of vitamin B₁₂ supplementation therapy. As the incidence of recreational N₂O gas inhalation is increasing in Korea, physicians must be alert to the N₂O induced SCD in patients presenting with progressive myelopathy.

Abstract Background and objectives Foot drop in postoperative period is very rare after spinal anesthesia. Early clinical assessment and diagnostic interventions is of prime importance to establish the etiology and to start appropriate management. Close follow-up is warranted in early postoperative period in cases when patient complain paresthesia or pain during needle insertion or drug injection. Case report A 22-year-old male was undergone lower limb orthopedic surgery in spinal anesthesia. During shifting from postoperative ward footdrop was suspected during routine assessment of regression of spinal level. Immediately the patient was referred to a neurologist and magnetic resonance imaging was done, which was inconclusive. Conservative management was started and nerve conduction study was done on the 4th postoperative day that confirmed pure motor neuropathy of right peroneal nerve. Patient was discharged with ankle splint and physiotherapy after slight improvement in motor power (2/5). Conclusions Foot drop is very rare after spinal anesthesia. Any suspected patient must undergo emergent neurological consultation and magnetic resonance imaging to exclude major finding and need for early surgical intervention.
Resumo Justificativa e objetivos Pé caído no período pós-operatório é muito raro após a anestesia espinhal. Avaliação clínica e intervenções diagnósticas precoces são de primordial importância para estabelecer a etiologia e iniciar o tratamento adequado. Um acompanhamento atento é justificado no pós-operatório imediato nos casos em que o paciente se queixa de parestesia ou dor durante a inserção da agulha ou da injeção de fármacos. Relato de caso Paciente do sexo masculino, 22 anos, submetido a cirurgia ortopédica de membros inferiores sob anestesia espinhal. Durante a transferência para a sala de recuperação pós-operatória, houve suspeita de pé caído durante a avaliação rotineira da regressão do nível espinhal. O paciente foi imediatamente enviado ao neurologista e uma ressonância magnética foi feita, mas não foi conclusiva. O manejo conservador foi iniciado e o estudo de condução nervosa foi feito no 4° dia de pós-operatório, o que confirmou a neuropatia motora pura do nervo fibular direito. O paciente foi dispensado com imobilizador de tornozelo e fisioterapia após ligeira melhoria da força motora (2/5). Conclusões Pé caído é muito raro após a anestesia espinhal. Qualquer paciente suspeito deve ser submetido à consulta neurológica de emergência e ressonância magnética para excluir o principal achado e a necessidade de intervenção cirúrgica precoce.

Os fascículos nervosos periféricos estão sujeitos a diferentes tipos de injúrias. Várias terapias são propostas pela literatura, entre elas, a laserterapia e a terapia farmacológica. Estudos têm mostrado a influência da laserterapia no metabolismo celular, de maneira a exercer uma ação positiva em níveis moleculares diminuindo o dano nervoso, aliviando a dor e acelerando os processos de reparação tecidual neural. Paralelamente os ribonucleotídeos pirimidínicos são bastante utilizados no tratamento de distúrbios ortopédicos degenerativos com compressão neuronal. O objetivo deste trabalho é relatar um caso clínico de uma paciente que possuía um pré-molar inferior incluso associado a um dente supra-numerário, cujo risco de lesão nervosa por meio da cirurgia era muito alto. Nas avaliações de imagem pode se notar uma relação de intimo contato do supranumerário com a cortical basal mandibular e com o canal mandibular. Foi elaborado um planejamento ortodôntico-cirúrgico, de forma a utilizar-se a laserterapia e ribonucleotídeos pirimidínicos para tratar a parestesia, classificada como neuropraxia, devido à longa exposição e ao tracionamento do dente. Este caso clínico ilustra opções de tratamento que os cirurgiões dentistas podem utilizar ao se depararem em situações clínicas inusitadas... (AU)
The peripheral nerve fascicles are subjected to different types of injuries. Several therapies are proposed in the literature, among them, laser therapy and pharmacological therapy. Studies have shown the influence of laser therapy on cellular metabolism, in order to exert a positive action at molecular levels, reducing nerve damage, relieving pain and accelerating neural tissue repair processes. In parallel, the use of pyrimidine ribonucleotides are widely used in the treatment of degenerative orthopedic disorders with neuronal compression. The objective of this study is to report a clinical case of a patient with an inferior pre-molar associated with a supra-dental tooth whose risk of Nerve injury through surgery was very high. In the image evaluations one can notice a relation of intimate contact of the supernumerary with the basal bone of the mandible and with the mandibular canal. Orthodontic-surgical planning was done in order to use laser therapy and pyrimidine ribonucleotides to treat paresthesia, classified as neuropraxia, due to long exposure and tooth traction. This clinical case illustrates treatment options that dentists can use when encountering unusual clinical conditions... (AU)

BACKGROUND: In 2015, workers dismantling a fluorescent lamp factory in Korea were affected by mercury poisoning from exposure to mercury vapor. CASE PRESENTATION: Eighteen out of the 21 workers who participated in the demolition project presented with symptoms of poisoning and, of these, 10 had persistent symptoms even at 18 months after the initial exposure to mercury vapor. Early symptoms of 18 workers included a general skin rash, pruritus, myalgia, sleep disturbance, and cough and sputum production. Following alleviation of these initial symptoms, late symptoms, such as easy fatigue, insomnia, bad dreams, and anxiety disorder, began to manifest in 10 out of 18 patients. Seven workers underwent psychiatric care owing to sleep disturbance, anxiety disorder, and depression, and three workers underwent dermatologic treatment for hyperpigmentation, erythematous skin eruption, and chloracne-like skin lesions. Furthermore, three workers developed a coarse jerky movement, two had swan neck deformity of the fingers, and two received care at an anesthesiology clinic for paresthesia, such as burning sensation, cold sensation, and pain. Two workers underwent urologic treatment for dysfunction of the urologic system and impotence. However, symptomatic treatment did not result in satisfactory relief of these symptoms. CONCLUSION: Awareness of the perils of mercury and prevention of mercury exposure are critical for preventing health hazards caused by mercury vapor. Chelation therapy should be performed promptly following mercury poisoning to minimize damage.

Abstract Introduction: After breast cancer surgery, many women may present quality of life (QOL) impairment due to the presence of discomfort as dysesthesia in the anterolateral region of the chest, armpit and/or medial part of the arm caused by intercostobrachial nerve injury (ICBN). Objective: To investigate the effects of Transcutaneous Electrical Nerve Stimulation (TENS) on dysesthesia intensity at the intercostobrachial nerve (ICBN) dermatome and QOL in women after breast cancer surgery. Methods: A randomized, double-blinded, placebo controlled clinical trial was conducted. Women undergoing axillary lymphadenectomy (AL), with dysesthesia on ICBN dermatome were included. Patients were divided into active and placebo TENS groups. TENS was applied with a frequency of 100 Hz, pulse duration of 100 µs and amplitude at the highest sensory intensity tolerable for 20 minutes during 20 sessions, three times a week, on alternating days. In the placebo TENS group, electrical current was delivered only during the first 45 seconds of application. Skin sensitivity was assessed by esthesiometry. Dysesthesia intensity was assessed with a visual analogue scale (VAS) and QOL with the EORTC QLQ-C30 and the specific EORTC QLQ-BR23 which is the Breast Cancer Module. Results: VAS decreased significantly over the 20 sessions in the active TENS group (p<0.006) and no difference was found between groups. There weren't significant differences in EORTC QLQ-C30 and EORTC QLQ-BR23 after 20 sessions or between groups. Conclusion: TENS decreased dysesthesia intensity in the ICBN dermatome after breast cancer surgery, but did not improve quality of life.
Resumo Introdução: Após cirurgia para câncer de mama, muitas mulheres podem apresentar prejuízo na qualidade de vida (QV) pela presença do desconforto como disestesia na região anterolateral do tórax, axila e/ou parte medial do braço, causada pela lesão do nervo intercostobraquial (NICB). Objetivo: Investigar os efeitos da Estimulação Elétrica Nervosa Transcutânea (TENS) na intensidade da disestesia no dermátomo do NICB e na QV após cirurgia de câncer de mama. Métodos: Ensaio clínico, controlado, randomizado, duplo-cego. Mulheres submetidas à linfadenectomia axilar (LA), com disestesia no dermátomo do NICB foram distribuídas em: TENS placebo e TENS ativo (um par de eletrodos autoadesivos) no trajeto do NICB, frequência de 100 Hz, duração de pulso de 100 µs, e amplitude no limiar sensorial máximo tolerado pela paciente, por 20 minutos, durante 20 sessões, três vezes na semana. A sensibilidade da pele foi avaliada através da estesiometria e foi considerada disestesia a partir do terceiro monofilamento (2,48 g). A intensidade da disestesia foi avaliada através da Escala Visual Analógica (EVA) e a QV com o EORTC QLQ-C30 e o EORTC QLQ-BR23. Resultados: A intensidade da disestesia diminuiu significativamente ao longo das 20 sessões no grupo TENS ativa (p<0,006), mas não houve diferença entre os grupos. Não houve diferenças significativas na QV após as 20 sessões entre os grupos. Conclusão: A TENS foi capaz de diminuir a intensidade da disestesia no dermátomo do NICB, mas não melhorou a qualidade de vida.

Notalgia paresthetica (NP) is a focal neuropathic itch condition manifesting in intense chronic or recurrent episodic itch in a hyperpigmented, macular, uni- or bilateral skin area located below and/or medially to the scapulae. Achieving satisfactory relieve in NP patients is challenging. In this case-series three female NP patients were treated with 8% capsaicin patches following a spatial quantification of their alloknetic area with a von Frey filament. The use of a von Frey filament in order to delimit the precise area of itch sensitization and thus patch application, proved clinically feasible. Although 8% topical capsaicin relieved itch in all three patients, the duration of the effectiveness varied greatly from only 3 days to >2 months. The treatment was well tolerated in the patients and there appear to be no significant hindrances to applying this treatment with NP as an indication, although it may only exhibit satisfactory effectiveness in certain patients. Placebo-controlled double-blinded trials are needed to confirm the effectiveness of the treatment and assess predictive parameters of the treatment outcome.

Pyridoxine deficiency and excess have both been implicated as causes of peripheral neuropathy. A 74-year-old man presented with paresthesia in both legs that first appeared 2 months previously. A nerve conduction study revealed axonal sensory polyneuropathy. He had consumed 100 milligrams of pyridoxine every day for 1 year, in the form of vitamin tablets. His blood levels of vitamin B6 were markedly elevated to above 250 nmol/L. This case indicates that the consumption of high-dose pyridoxine can cause sensory polyneuropathy.

La carnosina, dipéptido formado por los aminoácidos ß-alanina y L-histidina, tiene importantes funciones fisiológicas entre las que destaca su función antioxidante y las relacionadas con la memoria y el aprendizaje. Sin embargo, en relación con el ejercicio, las funciones más importantes serían las relacionadas con la contractilidad muscular, al mejorar la sensibilidad al calcio en las fibras musculares, y la función reguladora del pH. De este modo, se ha propuesto que la carnosina es el principal tampón intracelular, pudiendo llegar a contribuir hasta un 7-10% en la capacidad buffer o tampón. Dado que la síntesis de carnosina parece estar limitada por la disponibilidad de ß-alanina, la suplementación con este compuesto ha ido ganando cada vez más popularidad entre la población deportista. Por ello, el objetivo del presente estudio de revisión bibliográfica ha sido el de estudiar todos aquellos trabajos de investigación que han comprobado el efecto de la suplementación con ß-alanina sobre el rendimiento deportivo. Por otra parte, también, se ha intentado establecer una posología específica que, maximizando los posibles efectos beneficiosos, reduzca al mínimo la parestesia, el principal efecto secundario presentado como respuesta a la suplementación (AU)
Carnosine, dipeptide formed by amino acids ß-alanine and L-histidine, has important physiological functions among which its antioxidant and related memory and learning. However, in connection with the exercise, the most important functions would be associated with muscle contractility, improving calcium sensitivity in muscle fibers, and the regulatory function of pH. Thus, it is proposed that carnosine is the major intracellular buffer, but could contribute to 7-10% in buffer or buffer capacity. Since carnosine synthesis seems to be limited by the availability of ß-alanine supplementation with this compound has been gaining increasing popularity among the athlete population. Therefore, the objective of this study literature review was to examine all those research works have shown the effect of ß-alanine supplementation on athletic performance. Moreover, it also has attempted to establish a specific dosage that maximizing the potential benefits, minimize paresthesia, the main side effect presented in response to supplementation (AU)

Spinal cord stimulation (SCS) in trials involving external stimulation are easily conducted under local anesthesia. However, implantation of a permanent SCS system is painful, and can be intolerable in some patients. Epidural anesthesia can be used to perform the SCS implantation without discomfort if the patient can localize the area of paresthesia. However, little is known about epidural anesthesia for SCS. This paper reports 23 cases of permanent SCS with a cylindrical type lead implanted under the epidural anesthesia. Epidural anesthesia was sufficient in 22 patients without discomfort and significant complications. The remaining patient experienced incomplete epidural anesthesia and required additional analgesics to blunt the pain. All the leads were placed consistent with the patient's report of paresthesia area under epidural anesthesia. Thus, epidural anesthesia is an effective and safe method for the optimal placement of SCS to minimize the discomfort for patients without impairing patients' response to the intraoperative stimulation test.

BACKGROUND: notalgia paresthetica is a subdiagnosed sensory neuropathy presenting as a condition of intense itching and hyperchromic macule on the back that interferes with daily habits. OBJECTIVES: To determine the efficacy of treatment of notalgia paresthetica using oral gabapentin, assessing the degree of improvement in itching and influence on quality of life. Moreover, to evaluate the signs and symptoms associated with notalgia paresthetica. METHODS: We conducted an experimental, non-randomized, parallel, non-blinded study including 20 patients with clinical and histopathological diagnosis of notalgia paresthetica. After application of the visual analogue scale of pain adapted for pruritus and of the questionnaire of dermatology life quality index (DLQI), ten patients with visual analogue scale > 5 were given treatment with gabapentin at the dose of 300 mg/day for four weeks. The other ten were treated with topical capsaicin 0.025% daily for four weeks. After the treatment period, patients answered again the scale of itching. RESULTS: The use of gabapentin was responsible for a significant improvement in pruritus (p=0.0020). Besides itching and hyperchromic stain on the back, patients reported paresthesia and back pain. It was observed that the main factor in the worsening of the rash is heat. CONCLUSION: Gabapentin is a good option for the treatment of severe itching caused by nostalgia paresthetica. .

OBJECTIVES: Evaluate the effect on the application of low level laser therapy, in patients that have been previously intervened with a sagittal ramus split osteotomy and present neurosensory impairment due to this surgery, compared with placebo. Study DESIGN: This preliminary study is a randomized clinical trial, with an experimental group (n=17) which received laser light and a control group (n=14), placebo. All participants received laser applications, divided after surgery in days 1, 2, 3, 5, 10, 14, 21 and 28. Neurosensory impairment was evaluated clinically with 5 tests; visual analog scale (VAS) for pain and sensitivity, directional and 2 point discrimination, thermal discrimination, each one of them performed before and after surgery on day 1, and 1, 2 and 6 months. Participants and results evaluator were blinded to intervention. Variables were described with absolute frequencies, percentages and medians. Ordinal and dichotomous variables were compared with Mann Whitney's and Fisher's test respectively. RESULTS: Results demonstrate clinical improvement in time, as well as in magnitude of neurosensory return for laser group; VAS for sensitivity reached 5 (normal), 10 participants recovered initial values for 2 point discrimination (62,5%) and 87,5% recovered directional discrimination at 6 months after surgery. General VAS for sensitivity showed 68,75% for laser group, compared with placebo 21,43% (p-value = (0.0095). Left side sensitivity (VAS) showed 3.25 and 4 medians for placebo and laser at 2 months, respectively (p-value = (0.004). CONCLUSIONS: Low-level laser therapy was beneficial for this group of patients on recovery of neurosensory impairment of mandibular nerve, compared to a placebo

Cuando se colocan implantes dentales en el sector posterior de la mandíbula, el profesional debe decidir si utilizar la técnica troncular o la infiltrativa. Algunos estudios afirmaron que bajo anestesia infiltrativa el paciente podría advertir al profesional a través de su dolor, la cercanía del fresado o la colocación del implante al nervio dentario inferior. En contra posición, el objetivo de esta presentación de un caso clínico es evidenciar a través de tomografías pre y post quirúrgicas,que bajo anestesia infiltrativa la paciente no refirió dolor a pesar que el implante fue colocado íntimamente en relación al conducto dentario inferior.

BACKGROUND: The carpal tunnel syndrome (CTS) is the most common cause of severe hand pain. In this study we treated acute pain in CTS patients by means of local intradermal injections of anti-inflammatory drugs (mesotherapy). METHODS: In twenty-five patients (forty-five hands), CTS diagnosis was confirmed by clinical and neurophysiological examination prior to mesotherapy. A mixture containing lidocaine 10 mg, ketoprophen lysine-acetylsalycilate 80 mg, xantinol nicotinate 100 mg, cyanocobalamine 1,000 mcg plus injectable water was used. Sites of injection were three parallel lines above the transverse carpal ligament and two v-shaped lines, one at the base of the thenar eminence, and the other at the base of the hypothenar eminence. RESULTS: The day after the treatment, all but four patients reported a significant reduction in pain and paresthesias. After 12 months, 17 patients had a complete pain relief, eight patients reported recurrence of pain and sensory symptoms and four out of them underwent surgical treatment. CONCLUSIONS: With the obvious limits of a small-size open-label study, our results suggest that mesotherapy can temporary relieve pain and paresthesias in most CTS patients and in some cases its effect seems to be long-lasting. Further controlled studies are needed to confirm our preliminary findings and to compare mesotherapy to conventional approaches for the treatment of CTS.
