title: [Sensorineural deafness and aerospace flight].
abstract: OBJECTIVE
  To probe the relations between sensorineural deafness and flying in aviation or space.
  
  
  METHODS
  Case studies of sensorineural deafness were made in 36 pilots.
  
  
  RESULTS
  Unilateral deafness (n=15) and bilateral deafness (n=21) were found in 36 pilots, with mild deafness (n=9), moderate deafness (n=37) and severe deafness (n=11) in 57 ears. 19 cases were permanently grounded and 17 cases were still in a qualified position to continue their flying job.
  
  
  CONCLUSIONS
  Sensorineural deafness may hazard the flying in aviation or space, meanwhile the flying in aviation or space may lead to or aggravate sensorineural deafness.
