title: Otologic surgery following ear trauma.
abstract: OBJECTIVE
  To investigate common presentations and expected outcomes in patients with traumatically induced otologic dysfunction.
  
  
  METHODS
  Retrospective case review of patients who underwent otologic surgery for sequelae of otologic trauma over a 28-year period. Patients were stratified into major and minor trauma cohorts. Major trauma was designated as closed head injury with or without temporal bone fracture; lower-energy insults comprised the minor trauma group. Preoperative and postoperative audiograms were obtained and correlated with extent of injury.
  
  
  METHODS
  Tertiary referral center.
  
  
  RESULTS
  Major trauma accounted for 44.9 percent of all patients. The remaining 55.1 percent suffered minor trauma, of which simple traumatic tympanic membrane perforation was the most common insult (33.6%). Two hundred twenty-seven cases were performed on 214 patients. Pure tone averages improved a significant 20.8 dB to essentially normal levels postoperatively.
  
  
  CONCLUSIONS
  Regardless of injury extent, surgical rehabilitation of conductive losses attains excellent hearing results that surpass those historically reported for the chronic ear population.
