Endoscopic Transcanal Labyrinthectomy for Intractable Meniere's Disease: An Alternative to Transmastoid Labyrinthectomy?

초록

Objective: To describe a novel approach for intractable Meniere's disease exclusively through a transcanal endoscopic ear surgery (TEES) approach. Patient: A 56-year-old male with intractable Meniere's disease despite conservative treatment and chemical labyrinthectomy. Interventions: Transcanal endoscopic labyrinthectomy. Main Outcome Measure: Subjective vertigo control, surgical morbidity. Results: The TEES approach provided a wide exposure of the oval window. This facilitated removal of stapes crura and footplate. After widening of the oval window, the perilymph was suctioned, and gentamicin was injected through the oval window. The oval window was obliterated using the perichondrium of the tragal cartilage and fibrin glue. After 2 years of follow-up, there was no recurrence of vertigo. Conclusions: As a compelling alternative to the transmastoid approach, we propose endoscopic labyrinthectomy as an option for patients with intractable MD without functional hearing who have failed chemical labyrinthectomy. Additional studies are needed to determine the risk-benefit profile of this technique.
