Patients with sudden onset deafness usually show marked hearing restoration, but in patients with sudden onset total deafness or near total deafness full hearing is sometimes not recovered.<br>Between 1978 and 2000, we treated 247 patients with sudden deafness at our hospital, of which 71 had total deafness or near total deafness at the initial visit. In this retrospective study we divided patients into two groups: a total or near total deafness group (TD group), and the others group (O group). An analysis of case reports gave the following findings:<br>1) There were no significant differences in age, sex, or the number of days from disease onset to initial visit between the two groups.<br>2) The incidence of sudden deafness patients with vestibular symptoms in the TD group was significantly higher than in the O group.<br>3) In the TD group, the rate of complete recovery and marked improvement was significantly lower than that in the O group.<br>4) The rate of complete recovery and marked improvement in the TD patients with vestibule symptoms was significantly lower compared to those with similar symptoms in the O group.<br>5) Hearing prognosis in sudden deafness patients with Grade 4a at the initial visit was poorer compared to patients with other Grades. However, 43.5% of sudden deafness Grade 4b patients recovered to Grade 1.
