自覚症状からみた急性低音障害型感音難聴の臨床経過

抄録

Forty patients of an acute low-tone sensorineural hearing loss (ALHL) were studied based on their clinical diary in which the patients described six subjective symptoms such as tinnitus, ear fullness, autophonia, headache and dizziness.
Twenty-one patients complained of fluctuation of subjective symptoms in during a day. In seven cases, decrease of the fluctuation of subjective symptoms were observed as ALHL has been improved.
The fluctuation of hearing or the relapse of hearing loss was indicated by audiograms in twenty-two patients. Audiograms in some cases did not correlate to their subjective symptoms.
As it is difficult to perform frequent audiograms in the patients of ALHL, the clinical diary as well as the audiogram are very useful to study the clinical course of ALHL.
