Analysis Of Factors Relevant To Prognosis And Recurrence Of Sudden Sensorineural Hearing Loss

Objective: To investigate the related factors influencing the prognosis and recurrence of sudden sensorineural hearing lossMethods:Five hundred and thirty eight patients with sudden sensorineural hearing loss between January 2013 to April 2014 were analyzed. Twenty-five of the 538 patients were diagnosed as recurrent sudden deafness. The treatment results of the first and second attacks were summarized, and factors that may affect the curative effect were studied.Result: Of the 25 patients with recurrent SSNHL, the total effective rate was significantly lower than that of the patients with the first attack. The second attack of SSNHL was ipsilateral in 24 of the 25 patients, and the other one occurred in the contralateral ear. Factors such as tinnitus and/or aural fullness and gender didn’t affect the treatment results, while other factors such as accompanied diseases(hypertension or diabetes mellitus), vertigo, interval from onset to treatment, types of hearing loss affected the curative effect. Gender, age more than 34 years old, and tinnitus and/or aural fullness were found to be closely related to the therapeutic outcome of the recurrent patients. For the recurrent patients with low frequency SSNHL, though the recurrence rate was the highest, the treatment result was the best.Conclusion: The curative effect of recurrent SNHL is influenced by many factors. It is poorer than that of the first episode, and generally occurs in the same ear of the first attack.
