Abstract

UNTIL VERY recently, the endolymphatic sac has been a neglected part of the auditory mechanism, virtually ignored by pathologists and nearly forgotten by the clinician. Despite Portmann's¹ encouraging report in 1927 of relief of vertigo by uncovering and incising the sac wall, and the demonstration by Guild² that same year of endolymph resorption by the sac, otologists remained strangely forgetful of the presence and purpose of this structure. As an example, Williams³ in 1952 wrote a 340-page monograph on Meniere's disease in which he did not mention the possibility that deficient fluid resorption by the sac might induce hydrops of endolymph. Nor did he mention Portmann's operation in discussing various surgical procedures for Meniere's disease. In 1950 Bast⁴ redirected our attention to the sac, pointing out that its structure is ideally constituted for fluid resorption. Anson⁵ followed with his beautifully illustrated anatomical studies, and in
