Resumo: Vitiligo is a skin disease characterized by absence of melanin due to melanocytes destruction. AIM: to study the incidence of hearing alterations in patients with vitiligo. METHOD: prospective audiological evaluation, transient-evoked otoacoustic emission recordings and study the effects of suppression in 24 patients with vitiligo. Their ages ranged from 15 to 45 years. RESULTS: 21 patients (87.5%) had normal audiometry; 2 had unilateral hearing loss in the high frequencies and 1 had cochlear moderate hearing loss in the left ear. Of these 21 subjects, 66.7% had no otoacoustic emissions, suggesting cochlear dysfunction. Only 7 patients had otoacoustic emissions present in all frequencies (29.2%) and 17 (70.8%) did not have them, and the highest rate of no otoacoustic emissions happened in the right ear of males. Regarding the suppression study, 6 subjects failed, all of them were females, and their left ears were the most affected. CONCLUSION: the findings show that patients with vitiligo, particularly males, have a greater predisposition to cochlear dysfunction, especially in the right ear. As far as the suppression effect was concerned, there was a greater alteration in the female efferent system, particularly in the left ear. Hearing alterations did not vary as far as age is concerned, type of vitiligo and time of disease progression.

OBJETIVO: Verificar a ocorrência de alteração auditiva em indivíduos com vitiligo. MÉTODO: Avaliação audiológica, pesquisa das emissões otoacústicas evocadas transientes e do efeito de supressão em estudo prospectivo de 24 pacientes com vitiligo. A faixa etária variou de 15 a 45 anos. RESULTADOS: 21 pacientes (87.5%) apresentaram audiometria normal; dois apresentaram perda auditiva unilateral em freqüências altas e um apresentou perda coclear de grau moderado à esquerda. Destes 21 sujeitos, 66,7% tiveram ausência de emissões, sugerindo disfunção coclear. As emissões estiveram presentes em todas as bandas de freqüência em apenas 7 pacientes (29,2%) e ausentes em 17 (70,8%), com maior ocorrência de falha no sexo masculino, na orelha direita. Na pesquisa da supressão, seis indivíduos falharam, todos do sexo feminino, sendo a orelha esquerda a mais afetada. CONCLUSÃO: Pela análise das emissões otoacústicas verificou-se que os portadores de vitiligo possuem maior predisposição à disfunção coclear, com maior ocorrência no sexo masculino na orelha direita. Quanto ao efeito de supressão, houve maior alteração no sistema eferente em mulheres, com maior ausência à esquerda. As alterações auditivas não diferiram quanto à idade, tipo de vitiligo e tempo de evolução da doença.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de FonoaudiologiaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de DermatologiaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUNIFESP, EPM, Depto. de FonoaudiologiaUNIFESP, EPM, Depto. de DermatologiaUNIFESP, EPMSciELOABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-FacialUniversidade Federal de São Paulo (UNIFESP)Angrisani, Rosanna Mariangela GiaffredoAzevedo, Marisa Frasson de [UNIFESP]Pereira, Liliane Desgualdo [UNIFESP]Lopes, Celso [UNIFESP]Garcia, Michele Vargas [UNIFESP]2015-06-14T13:39:03Z2015-06-14T13:39:03Z2009-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion111-115application/pdfhttp://dx.doi.org/10.1590/S0034-72992009000100018Revista Brasileira de Otorrinolaringologia.
