Traumatic rupture of the eardrum with round window fistula
Abstract:
Traumatic perilymphatic round window fistula may manifest itself with minimal cochleovestibular symptoms. Its association with tympanic membrane perforation secondary to ear washing has previously never been published. The rapid complete recuperation of cochleovestibular function after a conservative obliteration of the round window niche with fat and a myringoplasty, leads us to suggest early surgical intervention when there is evidence or high suspicion of perilymphatic fistula with a traumatic membrane perforation.
