  • Abstract
  • Look Inside

 A man, aged 26, was suddenly attacked by deafnes and tinnitus accompanied by severe vertigo when he had closed the door of his car with a bang. A right tympanotomy performed after six day of the accident revealed accumulation of transparent fluid in the tympanum and round-shape perforations of the round window membrane. The perforations were found to be already closed with a thin membrane without the leakage of the perilymph. Following the operation the deafness failed to be improved but the vertigo gradually disappeared.

 So far, 75 ears of 73 patients who suffered rupture of the inner ear window were ascertained by operations ; these were reported in the literature. In order to clarify the clinical features of these cases clinical analysis are made : Deafness (95%) is more common than vertigo (71%). Differential diagnosis of these conditions from sudden deafness, Ménière's disease and benign paroxysmal positional vertigo is important. Association of the rupture of round window with head injury and barotrauma should be taken into consideration. Operative closure of the ruptured membrane appeared to be more effective in alleviating vertigo (93%) than deafness (20%). In our opinion the exploratory tympanotomy could be delayed for 2 or 3 weeks after onset of the symptoms, but it should be positively performed to close the perforation.
