    Clinical assessment of patients with primary and postparalytic hemifacial spasm: a retrospective study
    (Academia Brasileira de Neurologia - ABNEURO, 2007-09-01) Felício, André Carvalho [UNIFESP]; Godeiro-junior, Clecio de Oliveira [UNIFESP]; Borges, Vanderci [UNIFESP]; Silva, Sonia Maria de Azevedo [UNIFESP]; Ferraz, Henrique Ballalai [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    OBJECTIVE: To compared the clinical features of 373 patients with primary and postparalytic hemifacial spasm (HFS). METHOD: Data analyzed were gender, ethnicity, age at symptom onset, disease duration, affected side, distribution of facial spasm at onset, hypertension, family history of HFS, previous history of facial palsy and latency between facial palsy and HFS. RESULTS:The prevalence of patients with Asian origin was similar in both groups such as female/male ratio, mean age at symptom onset, disease duration, affected side and distribution at onset of facial twitching. The upper left side of the face was the main affected region at onset. Almost 40% of the patients in both groups had hypertension. A prevalence of vascular abnormalities on the posterior fossa was seen in 7% and 12.5% of both groups. CONCLUSION: The clinical profile and radiological findings of patients with primary and postparalytic HFS are similar. The association of hypertension with vascular abnormalities and HFS was not frequent.

    Colesteatoma causando paralisia facial
    (ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2003-10-01) Testa, Jose Ricardo Gurgel [UNIFESP]; Vicente, Andy De Oliveira [UNIFESP]; Abreu, Carlos E.c.

    Facial paralysis caused by cholesteatoma is uncommon. The portions most frequently involved are horizontal (tympanic) and second genu segments. When cholesteatomas extend over the anterior epitympanic space, the facial nerve is placed in jeopardy in the region of the geniculate ganglion. The aetiology can be related to compression of the nerve followed by impairment of its blood supply or production of neurotoxic substances secreted from either the cholesteatoma matrix or bacteria enclosed in the tumor. AIM: To evaluate the incidence, clinical features and treatment of the facial palsy due cholesteatoma. STUDY DESIGN: Clinical retrospective. MATERIAL AND METHOD: Retrospective study of 10 cases of facial paralysis due cholesteatoma selected through a survey of 206 decompressions of the facial nerve due various aetiologies realized in the last 10 years in UNIFESP-EPM. RESULTS: The incidence of facial paralysis due cholesteatoma in this study was 4,85%, with female predominance (60%). The average age of the patients was 39 years. The duration and severity of the facial palsy associated with the extension of lesion were important for the functional recovery of the facial nerve. CONCLUSION: Early surgical approach is necessary in these cases to improve the nerve function more adequately. When disruption or intense fibrous replacement occurs in the facial nerve, nerve grafting (greater auricular/sural nerves) and/or hypoglossal facial anastomosis may be suggested.

    Padronização das técnicas de secção do nervo facial e de avaliação da mímica facial em ratos
    (ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2006-06-01) Faria, Simone Damasceno De [UNIFESP]; Testa, Jose Ricardo Gurgel [UNIFESP]; Borin, Andrei [UNIFESP]; Toledo, Ronaldo N. [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    AIM: standardization of the technique to section the extratemporal facial nerve in rats and creation of a scale to evaluate facial movements in these animals before and after surgery. STUDY DESIGN: Experimental. METHOD: twenty Wistar rats were anesthetized with ketamine xylazine and submitted to sectioning of the facial nerve near its emergence through the mastoid foramen. Eye closure and blinking reflex, vibrissae movement and positioning were observed in all animals and a scale to evaluate these parameters was then created. RESULTS: The facial nerve trunk was found between the tendinous margin of the clavotrapezius muscle and the auricular cartilage. The trunk was proximally sectioned as it exits the mastoid foramen and the stumps were sutured with a 9-0-nylon thread. An evaluation and graduation scale of facial movements, independent for eye and vibrissae, was elaborated, together with a sum of the parameters, as a means to evaluate facial palsy. Absence of eye blinking and closure scored 1; the presence of orbicular muscle contraction, without blinking reflex, scored 2; 50% of eye closure through blinking reflex, scored 3, 75% of closure scored 4. The presence of complete eye closure and blinking reflex scored 5. The absence of movement and posterior position of the vibrissae scored 1; slight shivering and posterior position scored 2; greater shivering and posterior position, scored 3 and normal movement with posterior position, scored 4; symmetrical movement of he vibrissae, with anterior position, scored 5. CONCLUSION: The rat anatomy allows easy access to the extratemporal facial nerve, allowing its sectioning and standardized suture. It was also possible to establish an evaluation and graduation scale of the rat facial movements with facial palsy based on the clinical observation of these animals.

    Uso de peso de ouro palpebral para correção do lagoftalmo em pacientes com paralisia facial
    (ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2002-05-13) Testa, Jose Ricardo Gurgel [UNIFESP]; Aumond, Mariana Dantas [UNIFESP]; Figueiredo, Cláudia Regina [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Introduction: Lagophthalmus in facial palsy must be treated in order to avoid ocular complications. The gold weight eyelid implant as an alternative to tarsorrhaphy has been studied with good results. Aim: The purpose of this report is to study the effects of the gold weight eyelid implants for treatment of lagophthalmus. Study design: clinical retrospective not randomized. Material and method: 59 patients with Lagophthalmus associated with facial paralysis of many causes underwent gold weight implantation and were studied retrospectively. Results: All patients achieved satisfactory eyelid closure and improvement of ocular symptoms. 8.5% of patients had implant extrusion and 5% had infection. The average time with the implant varied from 6 months to 6 years, being removed in 20.3% of patients with recover of facial palsy. Discussion: Many methods have been described for enhance corneal protection in patients with facial palsy with different degrees of success and acceptance by the patient. The gold weight eyelid loading is a simple easy technique with good cosmetic result. The average time with the implant is inconstant and the complications are rare. Conclusion: Gold weight eyelid implants in patients with facial palsy have good results for the treatment of lagophthalmus and prevention of ocular complications.
