Abstract

Abstract : Objective: To investigate the role of intratympanic (IT) therapy in the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL). Methods: This study was a retrospective review. Patients were treated for ISSNHL from January 1, 2011 to April 12, 2015 with the following: pre/posttreatment audios, treatment initiated ≤90 days and idiopathic etiology. Fifty‐three ISSNHL patients were analyzed in the following subgroups: oral steroids (n = 8), combination oral+IT (n = 39), and IT (n = 6). Main outcomes measured were pre/posttreatment pure tone average (PTA) scores. Results: The PTA changes for all treatment groups improved by 8.0 ± 19.5 dB ( P = .004); for 31 patients treated ≤2 weeks after onset, PTA improved by 13.8 ± 16.6 dB ( P < .001). Multivariable generalized linear model for repeated measures was conducted to investigate the association between PTA changes for treatment groups adjusted for age, gender, time‐to‐treatment, and vertigo. Earlier time‐to‐treatment and older age were statistically correlated towards improved outcomes. As time‐to‐treatment increased by each day, change in PTA decreased by 0.324 (95% CI [0.12, 0.52], P = .002). As age increased by each year, PTA changes increased by 0.802 (95% CI [0.36, 1.24], P < .001). For the oral+IT group, PTA changes for concurrent oral+IT (n = 20, 7.10 dB) and delayed/salvage oral+IT (n = 19, 5.43 dB) were not statistically different ( P = .79); earlier time‐to‐treatment ( P = .001), and older age ( P = .006) remained statistically correlated towards improved outcomes. Conclusion: Results suggest outcomes can be improved with early identification and oral steroid therapy by primary care providers. Poorer prognosis for younger patients potentially suggests a need for more aggressive diagnostic and therapeutic management for this subgroup. Level of Evidence: 3b.
