Long-term results and change in quality of life after tenotomy of the stapedius and tensor tympani muscles in patients with Menière's disease
18. April 2018 (online)
The tenotomy of the stapedius and tensor tympani muscles represents a new therapeutic modality in the treatment of patients with Menière's disease refractory to conservative treatment measures.
We conducted a retrospective cross-sectional study in adults suffering from Menière's disease, to whom a tenotomy was performed without any other more invasive middle or inner ear procedures in the past. Aim of the study was to quantify the long-term effect of this intervention on the symptoms and the change in quality of life (Qol) of these patients. Questionnaires with general questions concerning the history of disease as well as the preoperative and current symptoms were sent by mail. Qol measurements were performed with the Glasgow Benefit Inventory (GBI) and with the Dizziness Handicap Inventory in the german version (DHI-G) both for the preoperative and for the current status.
The tenotomies were performed during the period from 2013 to 2016. Ten from the 14 operated patients answered the questionnaires. The mean follow-up was 23 months. During the follow-up period the vertigo attacks have been reduced in 90% of the patient collective. The bone-conduction threshold mean of the diseased ears has further deteriorated in 6 out of 10 patients. The postoperative DHI-G total score and the overall score of the GBI have shown a marked improvement except in 2 cases.
According to our results the tenotomy can be labeled as a low risk procedure with a high success rate in respect of the reduction in the dizziness episodes and the improvement of the disease specific and general Qol in patients with Menière's disease.
