Three new surgeries for treatment of intractable Meniere's disease

Objective: This study aimed to describe the rationales for and preliminary results of three new types of surgery for the treatment of intractable Meniere's disease, all involving insertion of a capillary tube into the endolymphatic duct. This study also aimed to compare the contrasting surgical strategies of endolymphatic sac enhancement versus sac supplantation. Study Design and Setting: The study design was a retrospective review of 129 surgeries conducted by the author at Chang Gung Memorial Hospital since 1993:51 cases of Huang/Gibson inner ear shunt implantation, 52 cases of intraductal capillary tube implantation (ICTI), and 26 cases of ICTIin combination with endolymphatic sac ballooning surgery (ESBS). Patients: This study is limited to patients with classic Meniere's disease whose vertiginous symptoms were disabling and refractory to dietetic and medical treatment. Main Outcome Measures: Comparison of preoperative and postoperative conditions (e.g., vertigo control, hearing, disability) using American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) 1985 criteria and chi-square statistical method was measured. Results: After 1 year of follow-up, use of the Huang/Gibson shunt resulted in a 94.1% vertigo control rate (complete or substantial) and fairly good hearing results, ICTI by itself resulted in an 88.5% rate of vertigo control and relatively unremarkable hearing results, and the ICTI in combination with ESBS (ICTI/ESBS) achieved a vertigo control rate of 96.1% in addition to good hearing results. Conclusions: The 1-year follow-up results for Huang/Gibson shunt implantation and sac-preserving ICTI/ESBS have approximately duplicated the excellent performance of the Arenberg implant after the same follow-up period, perhaps attributable in part to enhancement of endolymph flow through the endolymphatic duct.
