Endolymphatic sac drainage for intractable vertigo (method and experiences).
This paper describes a method of endolymphatic sac decompression and drainage. The method emphasizes widely exposing dura, avoiding skeletonization of the posterior semicircular canal and draining the sac via a T tube. The results of this procedure in 75 patients, including statistics in 46 ears are discussed. In patients with unilateral disease good results were obtained in control of vertigo in 94 percent of patients and significant improvement in cochlear function in over 30 percent.
