Insufficient evidence for benefits of surgery for Menière’s disease

Clinical question: 
How effective is surgery for the treatment of Menière’s disease?
Bottom line: 
The only surgical intervention which has been evaluated in randomised controlled trials (RCTs) is endolymphatic sac surgery. Two trials, involving a total of 59 patients, were included in the review, 1 comparing endolymphatic sac surgery with ventilation tubes and 1 with simple mastoidectomy. One study lasted 9 years, the other 12 months. Neither study reported any beneficial effect of surgery.
Caveat: 
Due to the different ways the outcome measures were obtained, and because not all the required data were reported, it was not possible to perform a meta-analysis. In total, 70% of participants in both the endolymphatic sac surgery groups and the comparator experienced some relief of complaints. There is no evidence to choose 1 surgical technique over another.
Context: 
Menière’s disease is characterised by 3 major symptoms: vertigo, deafness, and tinnitus or aural fullness, all of which are discontinuous and variable in intensity. A number of surgical modalities, of varying levels of invasiveness, have been developed to reduce the symptoms of Menière’s disease, but it is not clear whether or not these are effective.
