Clinical impact of adherence to a standardized treatment algorithm for idiopathic sudden sensorineural hearing loss: a multicenter cohort study

In this multicenter cohort, adherence to a standardized algorithm was moderate but was associated with improved hearing outcomes. In severe SSNHL, intravenous steroids enhance the early response-most notably in Grade 3-while salvage intratympanic steroid therapy considerably improves the final recovery rate. These findings support the implementation and optimization of the algorithm as well as the refinement of systemic dosing. Additionally, they highlight the importance of structured, guideline-based management in routine practice to improve outcomes in real-world SSNHL care.
