“…It has previously been shown that the outcome in untreated Bell's palsy becomes worse with increasing age (Langworth and Taverner, 1963) so the patients were further subdivided into young and older groups. There were 104 patients in the young group and 82 in the older group.…”

“…The presence or absence of denervation can be determined by the appearance of associated movements (Langworth and Taverner, 1963), and this is the strictest criterion available. The results now reported are based almost entirely on this finding.…”

“…It has sometimes been claimed that corticotrophin is more effective than oral steroid therapy in the treatment of inflammatory neurological disorders (Jonsson et al, 1951;Ross et al, 1958;Miller et al, 1961) but firm supporting evidence is lacking. After a suggestion from Professor H. Miller (personal communication, 1966) it was decided to compare these two agents in the treatment of Bell's palsy.…”

“…Longworth and Taverner 12 and Taverner 18 emphasized the value of the CMAP latency to predict the prognosis in Bell's palsy, but Esslen 3 " 5 and Zander Olsen 2 "' 21 demonstrated that the CMAP amplitude is the most important parameter.

-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.KEY WORDS: electroneurography, Bell's palsy, facial nerve.Eletroneurografia do nervo facial na paralisia de Bell: variabilidade na fase aguda e comparação entre técnicas RESUMO -O objetivo deste trabalho é determinar a variabilidade da eletroneurografia (ENG) do nervo facial na paralisia de Bell durante as primeiras duas semanas e investigar o valor da ENG na determinação de um prognóstico precoce utilizando-se dois métodos diferentes. O primeiro método compara a amplitude do potencial de ação muscular composto obtido no lado paralisado com o lado normal e o segundo método compara o potencial de ação muscular composto obtido no lado paralisado com valores normativos. Um grupo de 33 pacientes com paralisia de Bell foi seguido até a recuperação total ou pelo menos por quatro meses nos casos em que não houve recuperação. Observou-se que a amplitude do potencial de ação muscular composto estabiliza-¬ se em torno do sexto dia e que este é um bom momento para se realizar o exame e se estabelecer um prognóstico. Outra conclusão é que ambos os métodos são equivalentes para determinação prognóstica. PALAVRAS-CHAVE: eletroneurografia, paralisia de Bell, nervo facial.The pathologic process in idiopathic peripheral facial palsy stabilizes two weeks after the beginning of the illness 58 . The usual method of electroneurography (ENG) used to determine the prognosis in Bell's palsy consists of comparing the amplitude of the compound muscular action potential (CMAP) registered on the affected side with the CMAP amplitude obtained on the normal hemiface. A large difference implies a great number of nerve fibers affected and a worse prognosis.

“…In the remaining patients, the facial nerve was excitable but at a higher intensity than normal: this was attributed to partial denervation and only 49%o subsequently recovered completely. The poor prognostic significance of an inexcitable facial nerve was confirmed by Langworth & Taverner (1963) who reported that conduction in the facial nerve was retained in patients with partial denervation although it was often delayed. Peiris & Miles (1965) assessed the prognosis in patients with Bell's palsy using the method of electrogustometry.…”
