Abstract:
BACKGROUND AND OBJECTIVES: Hyperacusis, defined as increased sound sensitivity or decreased sound tolerence, has been reported to be related to tinnitus. The purposes of this study are to investigate the audiometrical characterization of hyperacusis and to evaluate the possible effect of hyperacusis on clinical presentation in tinnitus patients. MATERIALS AND METHOD: A total of 128 tinnitus patients, who visited the Tinnitus Clinic, Kangnam St. Mary's Hospital from May, 1999 to September, 2000, were included in this study. Their audiometrical study results were analyzed, and their hearing impairment was compared with those of normal controls. RESULTS: The prevalence of hyperacusis in the patients with tinnitus were as high as 37.8% according to the questionnare. Uncomfortable loudness levels to pure tone stimuli was significantly low in hyperacusis patients. In the tinnitus patients with normal hearing, the tinnitus handicap scores between hyperacusis and non-hyperacusis patients were significantly different, though the results of tinnitogram showed no difference. CONCLUSION: The hyperacusis test using pure tone stimuli may screen hyperacusic patients. It is necessary to consider the presence of hyperacusis in tinnitus patients so as to understand patient discomfort and to seek appropriate treatment modality.
