Full textOs nervos periféricos são estruturas expostas a traumatismo de ordem física, química e mecânica. Estas lesões podem vir a promover danos de diversas magnitudes, dentre as quais, a compressão, o estiramento e a secção, culminando com transtornos motores, estéticos e psicológicos. O presente estudo teve o objetivo de verificar a disposição dos fascículos do nervo facial por meio de estudo anatômico-histológico. Foram realizadas dissecações anatômicas em dez (10) cabeças de cadáveres com a idade entre 53-66 anos. Dissecamos o seguimento extratemporal do nervo facial bilateralmente e em seguida realizou-se o procedimento histológico de rotina para a observação da disposição dos fascículos do nervo facial no seu seguimento extratemporal em lâminas. Como resultados evidenciamos que o número de fascículos do seguimento extratemporal do nervo facial foi multifascicular em todas as amostras analisadas de nosso estudo, apresentando um número de 3 - 8 fascículos. Julgamos poder concluir baseados na metodologia empregada e nos resultados encontrados, que este achado vem somar e reforçar a necessidade de conhecimento em procedimentos cirúrgicos para enxertos de nervo facial (neurorrafias), uma vez que não há relatos em literaturas específicas sobre o tema e as literaturas disponíveis, consideram-no como sendo peculiarmente, monofascicular

Full textSUMMARY The facial nerve is an important surgeon concern while approaching the mandibular condylar process in the fracture surgical treatment. The preauricular and submandibular pathways are the two most frequently used approaches, which have a direct relation to the temporalis and marginalis mandibulae branches of the facial nerve, respectively. The lack of knowledge over possible variations on their anatomical distribution and mastery of the fundamental elements on surgical technique jeopardize the patient to the postoperative sequels. About the preauricular approach, there is a well-established tragus anterior incision. Some authors point out a continuous relaxing incision as a preventive maneuver to avoid lagophtalmus, for instance. The opening of an unique plane formed by the profound face of the temporoparietal fascia in the temporal region, deep face of periostheum over zygomatic arch and parotideomasseteric fascia as well generates a protective flap which includes facial nerve branches that cross up-and-forwardly the zygomatic arch. In regards to the submandibular approach, the angle and lower border of the mandible as well facial vessels are scientific well-known anatomic landmarks to place the initial incision, preventing the facial nerve from lesion. Nevertheless, recent scientific publications point out some frequent multiple branching patterns in the marginalis mandibulae, a facial nerve branch, always underneath platysm muscle in a variable caudad distance from lower border of the mandible. The lack of identification of the nerve may lead to different degrees of lower lid sequel by compression or strechening strengths, electric burns during imprecise adjacent bleeding vessels electric coagulation maneuver, or even a complete nerve transection responsible for a permanent paralysis of the lower lid. Thermal or mechanical injury should be avoided during haemostatic and synthesis maneuvers. The intra-operative pre-incisional mapping of the facial nerve (patient under general anesthesia), a very new method already on experimentation seems to be a promising tool in the nerve localization in the way to guide the surgeon before initial incision.

Introdução: A Paralisia Facial Periférica (PFP) uma alteração na função do nervo facial que acarretam comprometimentos funcionais, estéticos e psicológicos nos sujeitos acometidos por esta condição de saúde. A avaliação destes indivíduos é realizada por meio de escalas subjetivas e/ou avaliações objetivas que fornecem subsídio para uma proposta interventiva, tal como a Prática Mental (PM), técnica de treinamento com objetivo de aumentar a performance do indivíduo. Considerando a escassez de métodos de avaliação aplicados ao ambiente clínico e a falta de estudos sobre a influência da PM nesta condição, o presente estudo teve como objetivo inicial avaliar a confiabilidade do software Tracker para mensurar deslocamentos da mímica facial (MF) e como objetivo secundário analisar a influência da PM na reabilitação de indivíduos com PFP. Materiais e Métodos: Foram realizados um estudo transversal e um ensaio clínico não controlado. O estudo transversal foi realizado para avaliar a confiabilidade do software Tracker para mensurar deslocamentos durantes as MFs. Para este estudo foram recrutados indivíduos com e sem PFP os quais foram filmados realizando MF e tiveram os vídeos analisados por avaliadores independentes, para essa análise foi calculado o Índice de Correlação Intraclasse (ICC). Para o ensaio clínico não controlado foi realizado uma análise comparativa entre os momentos pré e pós intervenção nas medidas FGS, pela COPM, pela FDI e pelos deslocamentos faciais obtidos por meio do Tracker em indivíduos com PFP que foram submetidos a oito sessões de fisioterapia associada a PM. Resultados e Discussão: O software apresentou confiabilidade moderada e forte para avaliar deslocamentos das mímicas de fechar olhos e sorrir, não houve correlação para o movimento de fazer o bico, pois o software não foi capaz de mensurar os movimentos que ocorrem no plano ântero-posterior. Os indivíduos com PFP que finalizaram o protocolo de intervenção apresentaram melhora significativa na FGS, FDI, COPM e deslocamento da comissura labial afetada. Já para as escalas funcionais o grupo Controle do Movimento não apresentou diferença nas escalas, o grupo Facilitação e o grupo Relaxamento não apresentaram para a subescala de bem estar social da FDI. Este fato pode estar relacionado ao tamanho da amostra. Conclusão: O Tracker apresentou correlação forte e moderada para as mímicas de fechar os olhos e sorrir, podendo assim ser utilizado em ambiente clínico para mensurar estas mímicas. Já a PM demonstrou ser capaz de influenciar positivamente na recuperação funcional de indivíduos com PFP.
Introduction: Peripheral Facial Paralysis (PFP) is a alterations in facial nerve function that lead to functional, aesthetic and psychological impairment in the subjects affected by this health condition. The evaluation of these individuals is performed through subjective scales and/or objective assessments that provide support for an interventional proposal, such as the Mental Practice (PM), a training technique aimed at increasing the individual's performance. Considering the scarcity of evaluation methods applied to the clinical environment and the lack of studies on the influence of PM in this condition, the present study had as its initial objective to evaluate the reliability of the Tracker software to measure movements of the facial mime (MF) and as a secondary objective to analyze the influence of MP in the rehabilitation of individuals with PFP. Materials and Methods: A cross-sectional study and an uncontrolled clinical trial were conducted. The cross-sectional study was carried out to evaluate the reliability of the Tracker software to measure displacements during MF. For this study, individuals with and without PFP were recruited who were filmed doing MF and had the videos analyzed by independent evaluators. For this analysis the Intraclass Correlation Index (ICC) was calculated. For the uncontrolled clinical trial, a comparative analysis was performed between the pre and post intervention moments in of the FGS, COPM, FDI and the facial displacements obtained through Tracker in individuals with PFP who underwent eight sessions of physical therapy associated with PM. Results and Discussion: The software presented moderate and strong reliability to evaluate the movements of the mimics of close eyes and to smile, there was no correlation for the movement of the beak because the software was not able to measure the movements that occur in the anteroposterior plane . Individuals with PFP who completed the intervention protocol showed significant improvement in the FGS, FDI, COPM and displacement of the affected labial commissure. For the functional scales, the movement control group showed no difference in any scale, the Facilitation group and the Relaxation group did not present to the FDI social welfare subscale. This fact may be related to the size of the sample. Conclusion: The Tracker software presented a strong and moderate correlation for the mimics of closing the eyes and smiling, being able to be used in clinical environment to measure these mimics. PM has been shown to influence positively the functional recovery of individuals with PFP.

Introduction: Lesions affecting the peripheral nerves are quite common and can cause devastating damage to their lives of individuals, leading to important functional changes such as pain, morbidity and disability as well as, affecting their psychological condition. When the VII pair of cranial nerve is affected, patients may develop Peripheral Facial Paralysis (PFP), which include aesthetic, functional and emotional damages, as well as pain and discomfort. Treatment for lesions involving the peripheral nerves still presents limitations, since post-surgical results remain uncertain and unsatisfactory, especially in cases where nerve damage causes loss of substance. The use of autologous nerve grafting remains the "gold standard" of treatment; although it does present some important disadvantages. Trying to overcome all the difficulties and limitations, regenerative medicine together with tissue engineering have united their efforts with the purpose of improving the surgical techniques in the repair of this type of injury. Thus, in this context, many researches are being carried out with the aim of developing bioabsorbable materials associated with neurotrophic factors that can be used by the tubulization technique in substitution of the "gold standard". Objective: To evaluate the regeneration of the facial nerve of wistar rats submitted to a total transection of the nerve with loss of substance through the use of the tubulization technique with a PLGA / PCL polymer and autologous adipose stem cells. Material and Methods: 72 wistar rats were randomly divided into 3 groups (A, B, C) and submitted to a surgical procedure of injury (total transection with loss of substance) in the mandibular branch of the facial nerve, forming a gap of 6 mm. Immediately after the injury, the surgical procedure of nerve repair was performed according to the group to which they belonged. The rats of group A (control) were treated through the autologous nerve graft, with suture in the stumps. Group B rats were treated by the tubulization technique using a PLGA / PCL absorbable polymer sutured between the stents. The rats of group C were also treated by the tubulization technique, with the same polymer, but containing a quantity of autologous adipose stem cells in their interior. After 30, 60 and 90 days, the animals were euthanized for histological analysis. Results: The presence of the PLGA / PCL polymer, used by the tubulization technique, appears to have stimulated the formation of fibrosis in all evaluated groups. In 30 days there was no difference in the regeneration of nerve fibers between the three methods used to treat the facial nerve lesion of the rats used in this experiment. The use of stem cells associated with the PLGA/PCL tube presented better results than the "gold standard" in only 60 days. At 90 days, the "gold standard" and the technique of tubulization, without the use of stem cells, had the same results in nerve regeneration, and still, they were superior in relation to tubulization with the use of stem cells.
Introdu??o: As les?es que acometem os nervos perif?ricos s?o bastante comuns e podem causar danos devastadores na vida das pessoas, provocando altera??es funcionais importantes como, por exemplo, dor, morbidade e incapacidade, al?m de afetar a sua condi??o psicol?gica. Quando o s?timo (VII) par de nervos cranianos ? afetado, os pacientes podem desenvolver quadros de Paralisia Facial Perif?rica (PFP), que incluem preju?zos est?ticos, funcionais e emocionais, al?m de dor e desconforto. O tratamento para as les?es que envolvem os nervos perif?ricos ainda apresenta limita??es, visto que os resultados p?s-cir?rgicos continuam incertos e insatisfat?rios, principalmente nos casos em que a les?o ao nervo provoca perda de subst?ncia. O uso do enxerto aut?logo de nervo continua sendo o ?padr?o ouro? de tratamento, embora apresente algumas desvantagens importantes. Tentando suprir todas as dificuldades e limita??es, a medicina regenerativa, juntamente com a engenharia tecidual, t?m unido seus esfor?os com a finalidade de melhorar as t?cnicas cir?rgicas no reparo desse tipo de les?o. Nesse contexto, muitas pesquisas est?o sendo realizadas com o intuito de desenvolver materiais bioabsorv?veis, associados a fatores neurotr?ficos, que possam ser utilizados pela t?cnica da tubuliza??o em substitui??o ao ?padr?o ouro?. Objetivo: Avaliar a regenera??o do nervo facial de ratos wistar submetidos a uma transec??o total com perda de subst?ncia atrav?s do emprego da t?cnica da tubuliza??o com um pol?mero de PLGA/PCL e c?lulas tronco adiposas aut?logas. Material e M?todos: 72 ratos wistar foram randomicamente divididos em tr?s grupos (A, B, C) e submetidos a um procedimento cir?rgico de les?o (transec??o total com perda de subst?ncia) no ramo mandibular do nervo facial, formando um ?gap? de 6mm. Imediatamente ap?s a les?o, foi realizado o procedimento cir?rgico de reparo do nervo de acordo com o grupo ao qual pertenciam. Os ratos do grupo A (controle) foram tratados atrav?s do enxerto aut?logo de nervo, com sutura nos cotos. Os ratos do grupo B foram tratados pela t?cnica da tubuliza??o utilizando um pol?mero absorv?vel de PLGA/PCL suturado entres os cotos. J? os ratos do grupo C tamb?m foram tratados pela t?cnica da tubuliza??o, com o mesmo pol?mero, por?m contendo uma quantidade de c?lulas-tronco adiposas aut?logas em seu interior. Ao fim de trinta, sessenta e noventa dias, os animais foram eutanasiados para an?lise histol?gica. Resultados: A presen?a do pol?mero de PLGA/PCL, usado pela t?cnica da tubuliza??o, parece ter estimulado a forma??o de fibrose em todos os tempos avaliados. Em trinta dias n?o ocorreu nenhuma diferen?a na regenera??o das fibras nervosas entre os tr?s m?todos utilizados para o tratamento da les?o no nervo facial das cobaias neste experimento. O uso de c?lulas tronco, associadas ao tubo de PLGA/PCL, apresentou melhores resultados em rela??o ao ?padr?o ouro? somente em sessenta dias. Aos noventa dias, o ?padr?o ouro? e a t?cnica da tubuliza??o, sem a utiliza??o das c?lulas-tronco, tiveram os mesmos resultados na regenera??o do nervo e, ainda, se mostraram superiores em rela??o ? tubuliza??o com o uso de c?lulas-tronco.

Introdução: Há diversas situações médicas que exigem a descompressão aguda do nervo facial (NF), inclusive lesões traumáticas ou neoplásicas. No entanto, o NF é altamente vulnerável às oscilações térmicas e/ou mecânicas, as quais podem vir a ocorrer durante procedimentos cirúrgicos que requerem a utilização de brocas. Objetivos: Avaliar possíveis lesões térmicas ocasionadas por brocas de alta e baixa rotação, bem como comparar suas peculiaridades durante a mastoidectomia radical para descompressão do NF. Método: Oito espécimes de osso temporal obtidos de cadáveres foram submetidos à descompressão do NF pela técnica de mastoidectomia radical, usando brocas de alta rotação e baixa rotação, com irrigação contínua ou sob demanda. As oscilações de temperatura transoperatórias foram medidas através de sensores térmicos ligados ao osso temporal. Estes sensores seguiam o trajeto do NF, à distâncias de 10, 5 e 2mm, utilizando-se ponteiras cortantes de 2,4 milímetros ou ponteiras rombas diamantadas de 2,1mm. Resultados: O uso de brocas de alta velocidade com irrigação sob demanda provocou uma oscilação significativa de temperatura no NF quando comparadas às brocas de baixa velocidade sob irrigação contínua (p < 0,05). As temperaturas mais elevadas foram diretamente proporcionais a suas distâncias do NF. No entanto, nenhuma das brocas apresentou níveis de temperaturas altas o suficiente para causar dano ao NF. Conclusões: As oscilações térmicas secundárias ao uso de brocas em mastoidectomias radicais são consideradas um fator de risco potencial ao NF. Porém, as brocas de alta e de baixa velocidade atualmente disponíveis, sob condições adequadas, usando irrigação contínua e à uma distância limitada do NF, mostraram oscilações térmicas transoperatórias seguras. ______________________________________________________________________________________ ABSTRACT
Introduction: There are many medical situations that demand facial nerve decompression, including traumatic or neoplastic lesions. However, the facial nerve is highly vulnerable to thermal oscillations, which can be observed during surgical procedures that demand the use of drills. Objectives: To assess potential thermal injuries caused by drills of high and low speed, and compare their peculiarities during radical mastoidectomy for facial nerve decompression. Methods: Eight temporal bone flaps obtained from cadavers were submitted to facial nerve decompression by the radical mastoidectomy technique, using both high- and low-speed drills with continuous irrigation or irrigation on demand. The temperature oscillations during all of the procedures were measured using thermal sensors attached to the temporal bone, following the path of the facial nerve, at distances of 10, 5, and 2mm, using cutting burrs of 2.4mm or diamond ball burrs of 2.1mm. Results: High-speed drilling with irrigation on demand generated a higher temperature rise in the facial nerve when compared to low-speed drilling under continuous irrigation (p < 0.05). The closer the burrs were to the facial nerves, the higher the temperatures measured. Neither the high-powered drill nor the low-powered drill presented levels of temperatures high enough to cause facial nerve damage. Conclusions: Thermal oscillations secondary to the use of drills in radical mastoidectomies should be considered a potential risk factor in surgical procedures for facial nerve decompression. However, the recently developed disposable devices, high- or lowpowered drills were safely used in these procedures under adequate conditions, by using continuous irrigation and a limited distance from the facial nerve.

Full textBACKROUND: The gold standard treatment for traumatic transection of the FN continues to be end-to-end anastomosis using fibrin glue, which often yields unsatisfying results. OBJECTIVE: To test the outcome of a novel method of polyethylene glycol (PEG)-fusion on FN transection using electrophysiological and histophormometric parameters. METHODS: Wistar rats were divided into 4 groups. After FN transection, the control group was submitted to end-to-end anastomosis with microsutures. Group 2 was submitted to microsutures plus the PEG-fusion protocol. This protocol consisted in bathing nerve stumps with a calcium-free Krebs solution containing methylene blue (MB) before suturing. After suturing, the repaired nerve received a PEG solution followed by a calcium-containing Krebs solution. Group 3 received microsutures plus the MB solution and group 4 received microsutures plus the PEG solution. Compound muscle action potentials (CMAPs) were recorded before the intervention and 3 and 6 weeks afterwards. Histomorphometric analysis was done at 6 weeks time. RESULTS: The PEG-fusion protocol yielded larger CMAP amplitude, smaller CMAP duration at 3 and 6 weeks and a larger axon count and axon diameter. Between the other groups, no significant difference was seen. CONCLUSION: PEG-fusion produces better FN recovery after transection, when considering electrophysiological and histomorphometric analysis and may be of use in clinical scenarios of FN cut-severance followed by immediate repair

Full textBackground: Peripheral facial palsy is characterized by the permanent or temporary interruption of the functioning of the facial muscles. The middle cranial fossa (MCF) approach has been used for the decompression of the facial nerve (FN) when hearing needs to be preserved. In this work, we describe an innovative technique for the decompression of the FN through the MCF approach that allows the direct exposure of the labyrinthine and entire tympanic segment of the FN, with the preservation of inner ear function. Methods: Twenty cadavers heads were used in this study. The reference landmarks used were the middle meningeal artery, the greater superficial petrosal nerve, the arcuate eminence, the inferior petrosal sinus and the meatal plane following the petrous apex from its most anterior and medial portion. Results: The tympanic segment of the FN presented, on average, a total length of 11 ± 0.67mm to the right, and 11.5 ± 0.60mm to the left. The longitudinal lengths of bone window in the tegmen tympani were 16.8±1.67mm to the right, and 16.8 ± 1.20mm to the left. The cross-sectional lengths of the bone window in the tegmen tympani were 5.5 ± 1.20mm and 5.0±1.75mm to the right and left sides, respectively. The average value of elliptical area formed by the longitudinal and transversal lengths of the bone window made in the tegmen tympani were 72.5 ± 22.5mm2 to the right, and 65.9 ± 30.3mm2 to the left. Conclusion: The proposed technique can be used for the surgical decompression of the tympanic, labyrinthine and meatal segments of the FN through the MCF, without imposing a risk to hearing, in addition to reducing the surgical time and the risk to patients

Full textFacial motor evoked potential (FMEP) amplitude ratio reduction at the end of the surgery has been identified as a good predictor for postoperative facial nerve outcome. We sought to investigate variations in FMEP amplitude and waveform morphology during vestibular schwannoma (VS) resection and to correlate these measures with postoperative facial function immediately after surgery and at the last follow-up. Besides we analyzed the relationship between quantitative parameters. Intraoperative orbicularis oculi and oris muscles FMEP data from 35 patients undergoing surgery for VS resection were collected, then analyzed by surgical stage: initial, dural opening, tumor dissection (TuDis), tumor resection (TuRes) and final. Immediately after surgery, postoperative facial function correlated significantly with the FMEP amplitude ratio during TuDis, TuRes and final in both the orbicularis oculi (p´s=0.003, 0.055 and 0.028, respectively) and oris muscles (p´s=0.002, 0.104 and 0.014, respectively). At the last follow-up, however, facial function correlated significantly with the FMEP amplitude ratio only during TuDis (p=0.005) and final (p=0.102) for the orbicularis oris muscle. At both time points, postoperative facial paresis correlated significantly with FMEP waveform deterioration in orbicularis oculi during final (immediate, p=0.023; follow-up, p=0.116) and in orbicularis oris during TuDis, TuRes and final (immediate, p´s=0.071, 0.000 and 0.001, respectively; follow-up, p´s=0.015, 0.001 and 0.01, respectively). FMEP amplitude ratio and waveform morphology during VS resection seem to represent independent quantitative parameters that can be used to predict postoperative facial function. Event-to-baseline FMEP monitoring is quite useful to dictate when intraoperative changes in surgical strategy are warranted to reduce chances of facial nerve injury.
