Idiopathic sudden sensorineural hearing loss in Chumphae hospital,7 years Review

Abstract

Background : The hearing outcome of the idiopathic sudden sensorineural hearing loss (ISSNHL) can be improved after appropriate diagnosis and treatment. Oral corticosteroid is the treatment of choice that’s widely use to treatment on this condition. However the use of oral corticosteroid is still controversy.

Objective : The objective of this study is to review the hearing outcome of ISSNHL, prognostic factors and the use of oral corticosteroid.

Method : Retrospective descriptive study. Data collecting from medical records of the patients with diagnosis of idiopathic sudden sensorineural hearing loss in outpatient unit of Otorhinolayngology department of Chumphae hospital during June 2011 to April 2018.

Result : There were 144 patients in this study. 56 were males and 88 were females. The average age were 59.8 years old. All patients were unilateral hearing loss. 64 were right ears and 80 were left. Aural fullness was the most co-symptoms found by 70.8 percents. 47.2 percents were no underlying disease. Patients with steroid treatment were 87 and 57 were supportive treatment (non steroid group). In non-steroid group were divided into 2 subgroups 1) Mild SSNHL which were 27 patients 2) Patients who deny steroid use, 30 patients. Hearing improvement after 3months of steroid group were 52.9% and 66.7% for non-steroid group. In mild SSNHL subgroup improved by 77.8% and steroid denial subgroup were 56.7%. Patients with age under 60 years had more chance of hearing recovery(70%) compared with age over 60 years old(47.3%) with statically significant.

Conclusions : Idiopathic sudden sensorineural hearing loss has overall hearing improvement by 58.3 percent. Oral steroid show no benefit on hearing recovery when compared with non-steroid group. The good prognostic factor of Hearing recovery is age under 60 years old.
