Abstract
Ten cases of delayed endolymphatic hydrops (DEH) were seen in our clinic, all of which were of the ipsilateral type. Eight of those cases presented unilateral deafness and 2 cases demonstrated bilateral deafness. In all cases, the etiology of deafness was unknown. No pattern of uniformity was discerned in the clinical courses of these patients, but all 10 exhibited a gradual deterioration of vestibular function. Owing to unbalanced vestibular function, vertigo occurred in each case. In those cases where some vestibular function remained, vertigo or dizziness occurred repeatedly. Meniere's disease was also present.
