Class A results in Menière's disease.

Area of Science:

• Otolaryngology
• Neurosurgery
• Audiology

Background:

• Menière's disease is a chronic inner ear disorder.
• Surgical interventions are considered for refractory cases.
• Endolymphatic shunt procedures aim to decompress the inner ear.

Purpose of the Study:

• To evaluate the efficacy of the intramastoid endolymphatic shunt operation.
• To assess long-term outcomes in patients with Menière's disease.
• To propose a standardized metric for comparing surgical outcomes.

Main Methods:

• A retrospective analysis of 101 patients undergoing intramastoid endolymphatic shunt surgery.
• Minimum follow-up period of 2 years.
• Comparison with existing literature and introduction of an "efficacy ratio".

Main Results:

• A 76% success rate was observed.
• 22% of patients experienced treatment failure.
• Significant hearing improvements were noted in some patients, with 13 maintaining hearing at 15 dB or better and 11 gaining 25 dB or better.

Conclusions:

• The intramastoid endolymphatic shunt is a viable surgical option for Menière's disease.
• Standardized outcome reporting and further understanding of the disease's natural history are crucial for comparative studies.
• More research is needed on Menière's disease natural history for improved patient stratification.
