Abstract

Objective To investigate the relevant factors on the prognosis of sudden deafness. Method The clinical data of 133 patients (148 ears) with sudden deafness were analyzed retrospectively. Results Through systemic treatment, 25 cases got recovery, 18 cases were excellence and 39 cases were effective, the total effective rate was 61.7%(82/133). Univariate analysis showed that the factors related to the prognosis of sudden deafness were age, the time from onset to treatment, deafness classification,accompanied by vertigo or not and the duration of treatment. Patients with the age lower than 60, the earlier the time from onset to treatment, the lighter the deafness classification, not accompanied by vertigo and the longer duration of treatment got a better efficacy. Logistic regression analysis showed that the independent factors related to the prognosis of sudden deafness were the time from onset to treatment and deafness classification. Conclusion The etiology of sudden deafness is still unclear, the time from onset to treatment interval and the degree of hearing loss are the main factors affecting the prognosis of it, in clinic, it should be paid attention and took a early diagnosis and early treated so as to get good efficacy.
