Title in Portuguese
Avaliação da audiometria de potenciais evocados do tronco cerebral em patologias degenerativas da coluna cervical
Keywords in Portuguese

Patologias degenerativas
Potencial evocado
Abstract in Portuguese
Foram submetidos à Audiometria de Respostas Evocadas do Tronco Cerebral (BERA), 31 pacientes - grupo 1 (17 do sexo masculino e 14 do sexo feminino) com idade média de 54 à 56 anos (DP=10,2), com patologia degenerativa da coluna cervical, e 18 pacientes - grupo 2 (11 masculinos e 7 femininos) com média idade de 49 anos (DP=11,4), sem qualquer patologia evidenciada frente ao protocolo utilizado (anamnese, exame otorrinolaringológico, imitânciometria, perfil metabólico e radiografia de coluna cervical). A Audiometria de Tronco Cerebral, foi realizada com o aparelho da Amplaid com as intensidades em dB SPL (110 dB SPL) com uma taxa de estímulos de 11 cliques por segundo. Para análise estatística utilizou o teste t de Student para amostras pareadas para verificar se houve diferenças estatísticas significantes entre os grupos, adotando-se o nível de significância de 5% de probabilidade para rejeição da hipótese de nulidade. Não houve diferenças significativas entre as orelhas direita e esquerda para onda I, III e V no grupo 2 e para as ondas I e V no grupo 1, havendo diferenças significativas entre as orelhas direita e esquerda para onda III do grupo 1, considerando-se a latência. O resultado entre amostras independentes também evidenciou diferenças significativas entre os grupos 1 e 2 para onda III (latência). Não houve diferença em relação à amplitude e morfologia das ondas para amostras pareadas ou independentes no exame.

Abstract in English
Two group of patients were submitted to BERA (Brainstem Electric Response Audiometry). Group I was composed by 17 men and women with age average of 54,6 years old (SD:10,2), presented cervical cord degenerative pathology. Group II was composed by 11 men and 7 women, who did not present any pathology in the protocol used in the study (anamnese, otolarigological exam, imitânciometry, metabolic profile and X - ray of cervical cord ). BERA was accomplished by using Amplaid MK 12 device , with intensities of dB SPL (110 dB SPL), with a stimulus rate of 11 clicks a second. The statistical analysis made use of test t of student for matched samples to verify whether there any statistical significant difference among the groups , adopting the 5% significance levei of probability of rejection of the nullity hypothesis ( Curi, 1997 ). There was no significant difference between right and left externai ears for waves I, II. and V in group I and for waves and V in group II. There was significant difference between right and left externai ears forwave III, in group II, taking latency into account. The results among independent samples also showed evidence of significant difference between group I and group II, forwave III latency. There was no matched samples nor independent ones in the exams.
