Abstract:

Abstract Introduction and goals Idiopathic sudden sensorineural hearing loss is a hearing disorder of unknown cause . The spontaneous recovery rate ranges from 50 to 75% of the patients . Scientific experiments on animals support the present study in patients with sudden deafness treated with sounds . Patients and methods During the period 2003 - 2009 , patients with idiopathic sudden sensorineural hearing loss were administered steroids , piracetam and antioxidants , together with the addition of sounds by means of music and words . Results Comparing the results of patients treated with medication ( n = 65 ) and those treated with medication and sounds ( n = 67 ) , it was observed that patients treated with medication and sounds had higher recovery . Within the group of patients treated with medication and sounds , 25 ( 37% ) experienced complete recovery , 28 ( 42% ) good recovery , 11 ( 16% ) slight recovery and 3 ( 5% ) poor or no recovery . Conclusion The patients who recovered more than half of their audition accounted for 54% in the group treated with medication and for 79% in the group of patients receiving medication and sounds . Auditory recuperation showed no alterations , at least up to 12 months after therapy .
