Background and Objectives: Hearing outcomes and prognostic factors of idiopathic sudden sensorineural hearing loss (SSNHL) were investigated in patients who underwent combined intratympanic and systemic steroid therapy.
Subjects and Method:This study was performed by retrospective chart review. Clinical outcomes and prognostic factors were evaluated in 147 patients who received intratympanic steroid plus systemic steroid therapy.
Results: Complete hearing recovery was achieved in 36.7% (n=54) of the patients, partial recovery in 12.9% (n=19), slight recovery in 12.3% (n=18), and total recovery in 61.9% (n=91). Age was identified as an independent, negative prognostic factor for hearing recovery. The recovery rates of the down sloping and profound types were poorer than those of the up sloping type as determined by audiography.
Conclusion: The results of this study suggest that the combined treatment of intratympanic and systemic steroids for idiopathic SSNHL results in high hearing recovery rates, and that the down-sloping and profound types of audiogram patterns and age are negative prognostic factors.
