window can be used to control symptoms. It provides an alternative to the plugging and resurfacing techniques. This procedure is simple to perform, is reversible, and can be undertaken as a day case.
Otology/NeurotologyOutcome of intratympanic Gentamicin injection for Ménière Disease Leh-Kiong Huon (presenter); Te-Yung Fang; Pa-Chun Wang, MD, MScObjective: Intratympanic genemicin (ITG) is an option for the treatment of intractable Ménière disease (MD). The aim of this study is to investigate the outcomes of ITG for MD using evidence-based methodology.
Method:The MedLine database (1985~2010) was searched for original articles (level I or II in evidence strength) published in peer-reviewed journals concerning ITG for MD. Data extracted from these articles were reviewed and analyzed using meta-analysis technology.Results: A total of 15 articles were clitically appraised; 2 prospective, double-blinded randomized control trials (level I) and 13 prospective noncontrolled clinical trials (level II) were indentified. The pooled vertigo control rates (American Academy of Otolaryngology Head and Neck Surgery guidelines for Ménière disease) from 15 studies are: overall control rate 78% (class A, 95% CI 0.67-0.85), substantial control rate 56 % to 98% (class A and B, 95% CI 0.25-1.0) following ITG treatment (P = .0001). Hearing is worse in 0% to 61% (95% CI 0.02-0.83) after gentamicin treatment, which was neither clinically nor statistically significant (P = 1.000).
Conclusion:The critical literature and meta-analyses show that ITG can control vertigo for MD patients with limited injury to hearing. Quality of research has improved remarkably over the years. However, a large scale, randomized controlled trial is warranted to confirm the predicting factors for the true effectiveness of ITG in treating MD.
Otology/NeurotologyOutpatient labyrinthectomy Kevin X. McKennan, MD (presenter) Objective: With newly available anti-nausea/vertigo medications, selected patients can undergo transmastoid labyrinthectomy as an outpatient procedure.Method: Ten patients pretreated with a cocktail of Emend/ Transderm Scop Patch/Decadron underwent a transmastoid labyrinthectomy. These patients were all treated as outpatients. These 10 patients will be compared with 10 similar patients hospitalized after surgery. Method: A retrospective chart review was performed from January 1, 1999 until January 1, 2011, to identify patients under 17 years old who underwent a stapedectomy. Age, gender, pre-and postoperative audiograms, intraoperative findings including cause of stapes fixation, type of prosthesis used, and complications were recorded.Results: Eighteen children were identified who had undergone a stapedectomy. The cause of fixation included otosclerosis (n = 7), congenital footplate fixation (n = 9), and unknown cause (n = 2). The overall mean preoperative air-bone gap (ABG) was 35.7 dB (±10.4), compared with a postoperative mean ABG of 15.1 (±15.6) (P < 000.1). The mean postoperative ABG of 14.5 (±5.3) in the congenital footplate fixation gr...
