Study of the relationship between the degree of tinnitus annoyance and the presence of hyperacusis.

INTRODUCTION: Hyperacusis can be defined as a manifestation of an increased of central auditory pathways gain and can be considered a pre-tinnitus state. In some cases tinnitus can be caused by such increased gain. AIM: To evaluate the prevalence of hyperacusis in patients with tinnitus and its relation to the annoyance of tinnitus. MATERIALS AND METHODS: Retrospective study with patients from the neurotology service complaining of tinnitus in the first consultation were submitted to clinical evaluation, a questionnaire and audiological evaluation of tinnitus and hyperacusis. The degree of annoyance of tinnitus and hyperacusis was measured using a visual analog scale. RESULTS: We analyzed medical records of 309 patients, 169 (54.7%) females and 140 (45.3%) males. The mean age was 53 years. The median degree of tinnitus annoyance was 7. Hyperacusis was present in 57 (18.4%) patients, with a median degree of 5. The degree of annoyance due to tinnitus patients with hyperacusis was similar to that of patients without hyperacusis. CONCLUSION: Hyperacusis was present in 18.4% of patients with tinnitus. The degree of annoyance due to tinnitus had no correlation with the presence of hyperacusis.

Estudo da relacao entre o grau de incomodo de pacientes com zumbido e a presenca de hiperacusia / Study of the relationship between the degree of tinnitus annoyance and the presence of hyperacusis

Introdução: A hiperacusia pode ser definida como uma manifestação de ganho central aumentado das vias auditivas, compreendida como um estado pré-zumbido. Em alguns casos, o zumbido pode ser secundário a esse ganho aumentado. Objetivo: Avaliar a prevalência da hiperacusia em pacientes com zumbido e sua associação com o incômodo do zumbido. Materiais e métodos: Estudo retrospectivo envolvendo pacientes do ambulatório de otoneurologia com queixa principal de zumbido que foram submetidos a avaliação clínica, audiológica e a questionário de avaliação da hiperacusia e do zumbido. O grau de incômodo da hiperacusia e do zumbido foi classificado utilizando a Escala Visual Analógica. Resultados: Foram analisados prontuários de 309 pacientes, 169 (54,7%) do sexo feminino e 140 (45,3%) do sexo masculino, com idade média de 53 anos. O grau de incômodo do zumbido apresentou mediana de sete. A hiperacusia esteve presente em 57 (18,4%) pacientes, com mediana de grau de incômodo de cinco. O grau de incômodo pelo zumbido nos pacientes com hiperacusia foi semelhante ao dos pacientes sem hiperacusia. Conclusão: A hiperacusia esteve presente em 18,4% dos pacientes com zumbido. O grau de incômodo do zumbido não teve correlação com a presença da hiperacusia. .
