Objective:To describe a novel approach for intractable Meniere's disease exclusively through a transcanal endoscopic ear surgery（TEES）. Methods:This retrospective chart review included patients with intractable Menière's disease who underwent endoscopic transcanal labyrinthectomy in the Department of Otolaryngology Head and Neck Surgery, Guangxi Hospital Division, First Affiliated Hospital, Sun Yat-sen University, between February 2023 and October 2024. The first 70-year-old woman and the other 67-year-old woman, who underwent multiple conservative treatment and chemical labyrinthectomy during outpatient and hospitalization, had frequent vertigo, tinnitus and severe sensorineural deafness. The TEES approach provided a wide exposure of the oval window. The incus and the stapes were removed, expanded the oval window. The perilymph was suctioned, The saccule, utricule, macula utriculi and macula sacculi were removed. The ampulla tissue of the three semicircular canal were destroyed with the right-angle crochet. The oval window was obliterated using the perichondrium of the tragal cartilage and cartilage. Results:Two patients underwent endoscopic transcanal labyrinthectomy, and no intraoperative or postoperative complications were observed. Vertigo was controlled in 2 patients during the follow-up of 6 to 12 months. Two patients complained of total hearing loss after surgery. Conclusion:Even though this study presents a limited number of cases, endoscopic transcanal labyrinthectomy is a promising, safe, and effective procedure in selected cases. Additional studies are needed to determine the risk-benefit profile of this technique.
