Since Meniere’s original description, in 186I, of the disease that goes by his name, a variety of ~edical and surgical therapies have been advocated. In 1926, George Portmann believed that Meniere’s disease was due to a hypertension of the endolymph and successfully drained the endolymph by opening the endolymphatic sac, 12 years before Hallpike and Cairns first demonstrated the histopathological findings of endolymphatic hydrops in patients with Meniere’s disease, The operating microscope and modern otologic techniques have made many otologists, especially in the last two decades, to revive Portmann’s endolymphatic sac surgery. Many techniques have been presented aiming at modifying the original Portrnann’s operation or suggesting new procedures for the surgical decompression and dra-inage of the endclymphatic sac for the treatnent of Meniere’s disease, The aim of thio work is to review the different techniques employed in sur~ery of the endolymphatic sac, to evaluate the results of these techniques and to determine their efficacies in the trer•t~ent of Meniere’s dise:1se, |
