Subjects were 227 @entity1 with acute @entity1274 of 17,146 @entity1 seen at our ear, nose, and throat (E.N.T.) outpatient clinic from October 1994 through September 2000. Of these, 45 suffered from profound and moderate @entity2459 diagnosed when the arithmetical mean of hearing thresholds at 0.25, 0.5, 1, 2, and 4 KHz was 40 dB or worse. Of the 30 @entity1 whose medical treatment was started within 7 days of onset, 18 (60%) showed excellent or complete recovery of hearing, whereas none of the 15 whose treatment was started 8 days or late after onset showed satisfactory improvement. In general, the sooner treatment was started, the better hearing recovered. Idiopathic acute low-tone @entity1274 was found in 111 (49%) @entity1 with a female preponderance at a M:F ratio of 1:2.3, but no gender difference was seen in other diseases. The most common symptom was a feeling of pressure or fullness in the affected ear. Only 16% of @entity1 were aware of their hearing disturbance. Some 73 (66%) showed complete recovery. @entity9303 was diagnosed in 13, in whom hearing improved in only 2 (15%). Probable @entity9303 was diagnosed in 9 @entity1 who had 1 definitive episode of vertigo with low-tone @entity1274 , and their prognosis was good. The prognosis in 7 @entity1 with @entity393 due to @entity13378 and 1 with @entity393 was good, but normal hearing was not restored in 1 with mumps or 1 with @entity5513 . A @entity1 with @entity2316 had @entity393 and @entity346 toward the affected ear. Attacks of vertigo were controlled by diuretic therapy, but hearing recovery occurred by a little less than 10 dB. Some 35 @entity1 had mild idiopathic @entity393 and prognosis was relatively good. Hearing was disturbed after @entity542 in 2 and after nose blowing in 1, probably attributable to concussion of the labyrinth or the formation of a perilymphatic @entity292 . The diagnosis of this condition could not be made with certainty by surgical exploration of the ear.
