|
|
Sudden sensorineural hearing loss is not rare but its pathophysiology has not been fully determined and treatment regimen is still controversial at present.
1) Sex and affected side distribution of sudden hearing loss was 16 patients (44.4%) in male and 20 patients (55.6%) in female, 32 patients (88.9%) in unilateral cases and 4 patients (11.1%) in bilateral cases.
2) Complete recovery was seen in 10 ears(25%), partial recovery in 6 ears (15%), slight recovery in 9 ears (22.5%), and no response in 15 ears (37.5%).
3) In evaluation prognosis:
a) Patients treated within 10 days after onset showed better recovery rate (64.5%) than those treated 10 days or later (55.6%).
b) flat and ascending type hearing loss had a higher recovery rate (73.7%) than descending and profound loss (52.4%).
c) Patients with mild and moderate hearing loss showed better recovery rate (72.2%) than those with severe and profound loss (54.5%).
d) Patients with vertigo showed poorer recovery rate(47.6%) than those without vertigo(78.9%).
