Lateral Semicircular Canal Occlusion, Saccus Decompression And Cochlear Implantation: A New Approach For Refractory Menière's Disease And Functional Deafness
18 April 2018 (online)
For decompensated vestibular symptoms in cases of Menière's disease and single-sided functional deafness the combination of vestibular surgery and cochlear implantation can be reasonable approach. The objective of this study was the investigation of the success of a lateral semicircular canal occlusion with saccus decompression and cochlear implantation.
Seven patients with recurrent attacks of vertigo and severe sensorineural hearing loss caused by refractory Menière's disease were treated by the mostly one-stage lateral semicircular canal occlusion, saccus decompression and cochlear implantation. In three patients both sides were affected. The success of this method was evaluated by the Dizziness-Handicap-Inventory (DHI) performed preoperatively, postoperatively and after six weeks.
Prior to surgery the DHI of all patients indicated distinct physical, emotional and functional deficits. After surgery the impairment could be reduced in all cases even in case of bilateral affection. Regular to good audiological outcome could be achieved by cochlear implantation. Partial preservation of residual hearing was possible.
The combination of lateral semicircular canal occlusion, saccus decompression and cochlear implantation can be an effective option for patients with Menière's disease and severe hearing loss if vertigo symptoms cannot be treated conservatively. Because of the rather atraumatic lateral semicircular canal occlusion this method is possible even in cases of bilateral affection. Compared to the labyrinthectomy or triple semicircular canal occlusion it is the most atraumatic approach with similar effectiveness.
