For those who failed to respond to traditional and alternative treatment, there is still the last resort - surgeries. Here I want to review some most popular surgeries, in my opinion - the least destructive, for Meniere's disease. Endolymphatic sac shunt insertion or endolymphatic sac decompression (ESD)? In a healthy ear, fluid should flow to the endolymph sac through the endolymphatic duct which is located inside of the vestibular aqueduct. When endolymph cannot flow normally through the aqueduct due to an event such as blockage, endolymphatic hydrops form. With endolymphatic sac shunt insertion surgery, a shunt (i.e. drain) is placed into the sac which in turn allows fluid to drain into the local bony area. Endolymphatic decompression involves removal of bone surrounding the endolymph area. By doing so, any potential swelling of the endolymphatic sac is not inhibited by bone and as such the pressure does not increase within the sac. Because the endolymphatic sac is left intact, like endolymphatic shunt placement, endolymphatic sac decompression is not considered destructive in nature. Despite its nearly ninety years of use, research into the effectiveness of surgical manipulation of the endolymphatic sac remains somewhat inconclusive. In fact, some consider endolymphatic sac manipulation useless. But recently appeared a novel surgical technique with promising results - endolymphatic duct blockage (EDB). EDB is more effective than the traditional ESD in controlling the symptoms of Ménière's disease and there are no significant complications or adverse effects. Results: Twenty-four months postoperatively, 96.5% of the EDB group had achieved complete control of vertigo spells against 37.5% of the ESD group.

What were the results?
