Intratympanic Steroid Injection Complicated by Iatrogenic Perilymphatic Fistula: A Cautionary Tale.

Intratympanic (IT) steroid therapy is a mainstay treatment for sudden sensorineural hearing loss (SSNHL) for both initial therapy and salvage therapy. We report a rare case of iatrogenic perilymphatic fistula that resulted from trauma during an IT steroid injection for SSNHL. We discuss the diagnosis and treatment in the current case and compare it with previous reports from the literature. Laryngoscope, 131:2088-2090, 2021.
