Abstract

|
|
Purpose: The aim of this study is to evaluate the effectiveness of intratympanic steroid injection on patients with idiopathic sudden sensorineural hearing loss (ISSNHL) compared with patients who receive oral steroids alone.
Material and Methods: As a retrospective study for the patients with a history of ISSNHL and failure of steroid therapy, audiograms were performed and patients were included if SNHL of more than 20 dB occurred over less than 72 hours. Patients who received intratympanic steroid injection were compared with those who received oral steroids alone.
Results: Seventy patients met inclusion criteria and were included in the study. The number of patients with improvement in pure tone average in the injection group was 12 (33%) compared with 6 (18%) in the oral group. Fifteen (41.7%) of the injected patients did have improvement in speech discrimination scores of greater than 15% compared with only 4 (11,8%) in the oral group.
Conclusion: This study revealed that patients with ISSNHL who have failed oral steroid therapy obtain better hearing results with intratympanic steroids in comparison to oral steroids.
