[Long-term results of endolymphatic sac decompression and endolymphatic-mastoid shunting for Meniere's disease].

Objective: To investigate the efficacy of endolymphatic sac surgery for Meniere's disease, and compare the effects of endolymphatic sac decompression with endolymphatic-mastoid shunting.

Method: Twelve patients(13 ears) undergoing endolymphatic-mastoid shunting and eleven patients (11 ears) undergoing endolymphatic sac decompression were retrospectively compared for hearing results and vertigo controlled rates. All of them have been followed up for more than two years after surgery.

Result: According to Chinese Meniere's disease diagnosis and curative effect standard evaluation criteria published in 2006, for vertigo symptom of endolymphatic mastoid shunting group, 9 cases (69.2%) achieved grade A(completely controlled), 4 cases (30.8%) achieved grade B (fundamentally controlled). There were 8 cases (72.7%) with grade A, 2 cases (18.2%) with grade B and one case (9%) with grade C among 11 patients who received endolymphatic sac decompression. There was not statistically significant differences in postoperative speech pure tone average and vertigo controlled rate between the two groups.

Conclusion: Endolymphatic sac decompression and endolymphatic-mastoid shunting are effective management with less complication for intractable Meniere's disease. Particularly, the vertigo symptoms were controlled significantly. Patients with Meniere's disease in advanced clinical stages may also be relieved.
