OBJECTIVE: Intratympanic (IT) steroid administration for sudden sensorineural hearing loss is offered as salvage to patients who failed systemic steroid treatment. Our objective was to study the audiometric and clinical outcomes of patients given salvage therapy with high-dose IT steroids instilled via ventilation tube.
STUDY DESIGN: Retrospective case review.
SETTING: Academic secondary medical center.
PATIENTS: One hundred three patients >18 years of age with sudden sensorineural hearing loss who failed systemic steroids and received IT treatment between 2010 and 2018.
INTERVENTION: Following ventilation tube insertion, 1 ml of 10 mg/ml dexamethasone was instilled, twice daily, for 7 days.
OUTCOME MEASURES: Hearing assessment immediately before and after treatment. Tinnitus and vertigo complaints and risk factors were also retrieved.
RESULTS: Tinnitus had improved in 53 (52%) patients, vertigo in 4 (4%), and aural fullness sensation in 56 (55%) (p < 0.001, p = 0.344, p < 0.001, respectively). The mean pure-tone threshold difference across frequencies following treatment was between 0 and 6 dB. A significant improvement was observed at 250, 500, 1000 Hz (p < 0.001 in all), and at 2000 Hz (p = 0.035). No significant difference was found at 4000 and 8000 Hz (p = 0.055, p = 0.983 respectively). Mean pure-tone average improvement of 4.5 dB was detected in 61 (59%) patients (p = 0.001). The mean speech discrimination score improved by 7% (p = 0.001). Four (22%) diabetic and nine (20%) hypertensive patients had pure-tone average ≥10 dB improvement (p = 0.759, p = 0.852 respectively).
CONCLUSION: Although more than half of the patients improved clinically, the significance of the slight audiometric improvement should be weighed against the treatment protocol's complications.
