急性低音障害型感音難聴準確実例の検討

抄録

In the present study, the records of patients diagnosed as having suspected acute low-tone sensorineural hearing loss (ALHL) from among all the patients with hearing loss who visited a single clinic over a recent 6-year period were extracted, and a retrospective analysis of the recovery rate, recurrence, and tendency to progress to Ménière’s disease was performed. A total of 35 cases (6 men, 29 women) were diagnosed as having suspected ALHL. The 16 cases that were given isosorbide, Wu-Ling-San (Goreisan), and ATP as an initial treatment all recovered. The 19 patients who did not respond to this initial treatment were given steroids and vitamin preparations, and 7 of these cases recovered. The overall recovery rate was 65.7%. No improvement (no change) was seen in 12 cases (34.2%). Out of the 35 cases, a one-year follow-up examination was performed in 14 cases (40%). Out of the cases who underwent a one-year follow-up, recurrences had occurred in 3 (8.6%) cases. Out of the patients with recurrences, 1 case (2.9%) had progressed to Ménière’s disease.
