Vestibular neurotomy is a functional surgery for Meniere's disease in the event of medical treatment failure. The aim of the study was to assess the efficacy and complications of vestibular neurotomy, and to address the question of postoperative compensation.
Material and method
All patients included in this retrospective study underwent a vestibular neurotomy at our center between 2009 and 2016. A preoperative evaluation was performed including MRI, audiometry, and videonystagmography. The functional level of disability was evaluated by the Dizziness Handicap Inventory (DHI) score. In all patients suboccipital retrosigmoid approach was performed. All patients underwent early postoperative vestibular rehabilitation. One month and two years after surgery, we assessed the effectiveness of treatment on dizziness, disability and imbalance. At the time of this study (2 to 8 years), DHI and patients’ satisfaction by patient's global impression of change (PGIC) scale were evaluated.
Fifteen patients aged between 42 and 74 years of age were included in our study. Postoperative complications occurred in two patients (meningitis and a wound infection). At one month, all patients had a dramatic clinical improvement with decreased vertigo. Two years after surgery, 85% of the patients were cured and had no dizziness or balance disorder. Only one patient experienced bilateralization and only one had a persistent poor compensation.
Vestibular neurotomy is a very effective treatment in the case of Meniere's disease resistant to medical treatment, with very good functional results and an extremely low failure rate.Le texte complet de cet article est disponible en PDF.
