Minimally invasive laser contraction myringoplasty for tympanic membrane atelectasis.

OBJECTIVE: We sought to develop a minimally invasive surgical technique using the CO(2) laser to reduce or eliminate tympanic membrane atelectasis in a select group of patients. STUDY DESIGN: Thirty-seven ears with varying degrees of tympanic membrane atelectasis underwent CO(2) laser myringoplasty with the patients under intravenous sedation in the operating room setting. Atelectasis severity was graded for each patient and documented before and after laser myringoplasty through photodocumentation. Patients were followed for 1 year with comparison tympanic membrane photography. SETTING: The study was conducted in a tertiary care private otology-neurotology practice. RESULTS: Laser myringoplasty significantly reduced retraction pocket severity in most patients. No patients required resection of the retraction pocket or tympanoplasty. The most favorable outcomes were observed in patients with atelectasis addressed early rather than later in its more advanced stages. CONCLUSION: Laser contraction myringoplasty can reduce or eliminate atelectatic areas of the tympanic membrane through immediate contraction and "tightening" of the tympanic membrane tissues. Clinicians should use a standardized tympanic membrane atelectasis grading format. SIGNIFICANCE: A minimally invasive surgical technique for addressing tympanic membrane atelectasis is described, and a tympanic membrane atelectasis grading system is presented based on size, location, and depth of the atelectatic region.

Endolymphatic sac-vein decompression for intractable Meniere's disease: long term treatment results.

OBJECTIVES: We sought to determine the long-term efficacy of endolymphatic sac-vein decompression surgery on patients with classic Meniere's disease. STUDY DESIGN AND SETTING: Using the 1995 American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium criteria, starting stage, functional level, vertigo class, and hearing results were addressed. We studied 68 patients with classic Meniere's disease from a tertiary, private otology-neurotology practice. Patient data were gathered by retrospective chart review, questionnaire, and patient interview. All patients underwent endolymphatic sac-vein decompression with an average follow-up period of 55 months. RESULTS: Median functional level before surgery was level 4, improving to level 2 after surgery. Eighty-one percent of patients showed improvement in functional level, 12% remained stable, and 7% declined. Long-term vertigo control was 47% in class A, 25% in class B, 9% in class C, 3% in class D, and 16% in class F. Twenty percent of patients were in hearing stage I Meniere's disease; 31%, stage II; 44%, stage III; and 5%, stage IV. Eighteen percent of patients showed improvement in hearing class, 64% were stable, and 18% declined. CONCLUSION: Endolymphatic sac-vein decompression surgery is a safe, nondestructive surgical option for Meniere's disease that offers durable control of vertigo and stabilization of hearing for the majority of symptomatic patients. SIGNIFICANCE: The beneficial long-term outcome of the endolymphatic sac-vein decompression supports its continued use as a first-line treatment option in intractable Meniere's disease.
