Outcomes of transtympanic dexamethasone perfusion using the MicroWickTM in patients with Ménière's disease: A cross-sectional study.

PURPOSE: To assess the efficacy of a 4-week transtympanic dexamethasone perfusion using the Silverstein MicroWickTM in patients with Ménière's disease. MATERIALS AND METHODS: A self-reported questionnaire was designed and sent to patients who underwent transtympanic dexamethasone perfusion using the Silverstein MicroWickTM from January 2017 to December 2020. A retrospective chart review was conducted to gather demographic and audiological data of those who responded. RESULTS: Forty respondents were separated into Group 1 (n = 34), who required no further procedure, and Group 2 (n = 6), who required additional procedure for Ménière's disease. In Group 1, 50% reported subjective improvement in tinnitus, 59% in aural fullness, 79% in vertigo, and 21% in hearing loss after the MicroWickTM treatment. A statistical analysis of the scores revealed that the improvement in aural fullness and vertigo met significance (p = 0.03 and p = 0.002, respectively). In Group 2, no significant change was seen in their symptoms. Audiological data showed no significant change in the pure tone average or the word recognition score after the treatment. CONCLUSION: Transtympanic dexamethasone perfusion using the Silverstein MicroWickTM is a well-tolerated treatment option for patients with Ménière's disease. Our survey data suggest its significant efficacy in reducing aural fullness and vertigo attacks in these patients. Prospective studies will be conducted to further establish its potential role in successfully managing patients with Ménière's disease.

Minimally invasive surgery for the treatment of hyperacusis: New technique and long term results.

OBJECTIVE: A minimally invasive surgery developed by the senior author has previously been reported to significantly improve sound tolerance after surgery. This report compares the new versus original surgical technique used and long-term results of all patients who have undergone minimally invasive surgery for hyperacusis. STUDY DESIGN: A prospective, IRB approved clinical research trial at a single institution with surgery performed by the author (HS). SETTING: All patients were evaluated and treated at a tertiary level otologic referral center. SUBJECTS AND METHODS: 47 subjects were enrolled from 2014 through 2019, 40 met inclusion criteria including adequate follow-up in the analysis. All subjects underwent oval and round window reinforcement. 20 subjects underwent surgery before 2017 with the original technique of round window reinforcement. 20 subjects underwent new technique with additional oval window and stapes reinforcement. RESULTS: 80% of subjects who underwent the new surgical technique had improvement in hyperacusis symptoms after surgery compared to 60% of subjects who underwent the original technique. Long term follow-up showed sustained results with both techniques with a mean follow-up of 2 years after surgery. CONCLUSIONS: The most recent, newer technique employed appears to have an 80% success rate in improving sound tolerance with small changes to hearing. The improvement in hyperacusis symptoms after surgery is significant and now found to be sustainable with a mean follow-up of 2 years after initial surgery. Psychological measures of anxiety and depression also were found to be significantly improved after surgery in the newer technique group.
