Endolymphatic sac surgery for Menière's disease

Area of Science:

• Otolaryngology
• Neurosurgery

Background:

• Menière's disease is a chronic inner ear disorder.
• Endolymphatic-mastoid Silastic shunt surgery is a treatment option.

Purpose of the Study:

• To evaluate the long-term efficacy of endolymphatic-mastoid Silastic shunt surgery for Menière's disease.
• To assess surgical outcomes and patient-reported symptom relief over time.

Main Methods:

• A retrospective analysis of 122 Menière's disease patients undergoing endolymphatic-mastoid Silastic shunt.
• Outcomes were classified using American Academy of Ophthalmology and Otolaryngology 1972 criteria.
• Recent outcomes from 35 cases with shorter follow-up were compared.

Main Results:

• Initial success rates (Class A/B) were 63% in the overall cohort and 82% in recent cases.
• Surgical success rate decreased over time.
• 16% of patients with improved symptoms still reported fluctuating issues; 3 new cases of otolithic crisis occurred post-surgery.
• 70% of patients with good outcomes experienced vertigo recurrence or hearing loss after salt-loading tests.

Conclusions:

• The endolymphatic-mastoid Silastic shunt procedure shows diminishing success rates with longer follow-up.
• Surgery may alter Menière's disease symptoms but does not provide a definitive cure.
• Further research is needed to understand long-term disease modification and treatment efficacy.
