Objective: Patients with sudden sensorineural hearing loss (SSHL) can benefit from systemic steroid therapy. Unfortunately, some patients are not candidates for steroid therapy due to concern over possible complications. Furthermore, not all patients will benefit from steroid administration. This study evaluates the potential benefits and safety of treating patients with SSHL refractory to oral steroids with intratympanic steroid therapy.
Methods: A retrospective case review was performed on all patients who presented with sudden sensorineural hearing loss refractory to oral steroid therapy during the past year. Seventeen patients were identified. All patients underwent intratympanic steroid administration, via MicroWick placement and/or round window catheter placement.
Results: Nine patients with sudden sensorineural hearing loss showed an improvement with intratympanic steroid therapy, consisting of MicroWick placement with dexamethasone drop (Decadron) administration for 1-2 weeks and/or round window catheter placement with steroid perfusion. Only one of the patients presenting with hearing loss present for greater than 8 weeks benefited from intratympanic therapy. Complications were few and included tympanic membrane perforation, chronic otitis media, dysequilibrium, and dysguesia.
Conclusions: Intratympanic steroid therapy can be beneficial in treating patients with sudden sensorineural hearing loss refractory to oral steroid use.
