    Facial electroneurography in Bell's palsy: variability in the early stage and comparison between interpretation methods
    (Academia Brasileira de Neurologia - ABNEURO, 1996-09-01) Medeiros, Jovany Luis Alves de [UNIFESP]; Nobrega, João Antonio Maciel [UNIFESP]; Andrade, Luiz Augusto Franco de [UNIFESP]; Novo, Neil Ferreira [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    To determine the variability of the abnormalities found in the electroneurography (ENG) of the facial nerve in cases of Bell's palsy during the initial two week period was one of the objectives of the authors. A second one was to investigate the value of ENG as a tool to determine an early prognosis of recovery utilizing two different methods. In the first one the amplitude of the compound muscular action potential (CMAP) obtained on the paralyzed side was compared to this potential on the opposite (normal) side. The second method compared the CMAP on the paralyzed side to normal standardized data from normal individuals. A group of 33 patients with Bell's palsy was followed until total recovery or for at least 4 months, if the recovery was not achieved earlier. It was observed that amplitude of the CMAP become stable towards the sixth day of palsy and this is a good time to establish the prognosis. Another conclusion is that both methods were equivalent to determine the prognosis in Bell's palsy.

    Relação da presença de hiperacusia em pacientes com paralisia facial periférica de Bell
    (ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2004-12-01) Liriano, Raquel Ysabel Guzmán [UNIFESP]; Magalhães, Sandra Lira Bastos De; Barros, Flávia [UNIFESP]; Testa, Jose Ricardo Gurgel [UNIFESP]; Fukuda, Yotaka [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Pontifícia Universidade Católica de São Paulo
    Bell's palsy is a unilateral facial paralysis of sudden onset and unknown cause. It may affect salivation, taste and lachrymation depending on the site of facial nerve involvement. Patients can report supersensitive hearing. The stapedius reflex is absent in patients with Bell's palsy. AIM: The objective of the present study was to check if patients with Bell's palsy present hyperacusis. STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: Eighteen patients with peripheral facial paralysis were randomly selected and examined. Complete ENT evaluation was performed, including Hilger facial nerve stimulator, Schirmer's test, electrogustometry, pure tone testing, speech audiometry, immittance testing and discomfort loudness levels. The group aged 31-40 years was the most affected by peripheral facial paralysis in this sample. RESULTS: The incidence was higher in females (61%). The right side of the face was involved in 56% of patients. As to local involvement, grade IV was observed in 44% of cases and grades III and V in 28% of patients each. Only one patient (5.5%) complained of hyperacusis. All studied patients presented reduced tolerance threshold in the audiometric graphs, and stapedius reflex protects these patients by 16dB on average. CONCLUSION: Therefore, we could conclude that the frequency of complaints of hyperacusis in patients with Bell's palsy was similar to that of the general population; however, in audiometric terms, the tolerance threshold in the paralyzed side was lower when compared with the normal side.

    Valor prognóstico de dados clínicos em paralisia de Bell
    (ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2005-08-01) Kasse, Cristiane Akemi [UNIFESP]; Cruz, Oswaldo Laércio Mendonça [UNIFESP]; Leonhardt, Fernando D.

    Electroneurography (ENoG) and clinical staging are currently the methods of choice to indicate prognosis in Bell's palsy, although ENoG is an electrophysiological test not universally available. AIM: Identify other options of prognostic evaluation based upon clinical aspects and minimal electrical stimulation test allowing prognostic measurement in almost any circumstances. STUDY DESIGN: historic cohort. MATERIAL AND METHOD: Chart review of 1,521 cases of IPFP, analyzing the following clinical aspects: gender, age, paralyzed side, installation mode, previous symptoms, associated symptoms and minimal electrical stimulation test (Hilger test) and its statistical correlation to facial palsy evolution after 6 months. RESULTS: Data indicated that patients above 60 years old had worse prognosis in comparison with patients under 30 years old. A progressive mode of paralysis installation, absence of previous symptoms, concomitant vertigo and response superior to 3.5 mA at minimum electrical stimulation test were also related to worse prognosis. On the other hand, the absence of concomitant symptoms, diminished tearing and sudden onset were related to better prognosis. CONCLUSION: Clinical factors and Hilger's test can accurately indicate the prognosis in cases of Bell's palsy when ENoG is not available.
