Abstract
OBJECTIVE: The purpose of this retrospective study was to investigate the difference in treatment outcomes for patients with idiopathic sudden sensorineural hearing loss (SSNHL) undergoing concurrent or sequential intravenous (IV) and intratympanic (IT) steroid therapies.
METHODS: Patients with idiopathic SSNHL admitted to Taipei Veterans Hospital from August 2011 to August 2012 were enrolled. Patients were treated with both IV dexamethasone 5 mg b.i.d. for 5 days, then tapered over 6 days, and IT injections of dexamethasone 5 mg daily. The administration of IV and IT steroids was given either concurrently or sequentially (IV steroid was administered from days 1-5 followed by IT steroid treatment starting on day 4 or day 5). The hearing outcomes of the concurrent and sequential groups were analyzed.
RESULTS: Overall, after ≥2 months following treatment, across frequencies ranging from 250 to 8,000 Hz and pure-tone average (PTA) assessments, hearing improvements were similar between treatment groups, except at the frequencies of 4,000 and 8,000 Hz where the concurrent treatment group had greater hearing gain than the sequential group (4,000 Hz: 30.68 ± 28.96 vs. 14.52 ± 24.06 dB, respectively, p = 0.042; 8,000 Hz: 22.62 ± 23.59 vs. 7.67 ± 21 dB, p = 0.030). Across frequencies and PTA assessments, a similar percentage of patients had ≥20-dB gains in hearing compared with patients treated sequentially, except at 8,000 Hz where a greater percentage of patients in the concurrent group (57.1%) than the sequential group (23.3%) (p = 0.014) had ≥20-dB hearing gains.
CONCLUSION: The findings suggest that both concurrent and sequential treatment improve hearing in patients with idiopathic SSNHL, and that concurrent treatment may show greater benefit than sequential therapy, particularly at high frequencies.
