title: Irradiated rib cartilage graft for reconstruction of the tympanic membrane: preliminary results.
abstract: OBJECTIVE
  To evaluate the advantages, disadvantages, safety, and results in reconstruction of the tympanic membrane using irradiated rib cartilage.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  A tertiary referral center.
  
  
  METHODS
  All patients who had > or =6 months follow-up who underwent tympanoplasty or tympanomastoidectomy using irradiated rib cartilage graft at our institution from January 1, 1993 to December 31, 1996.
  
  
  METHODS
  Tympanoplasty or tympanomastoidectomy using homologous irradiated rib cartilage as graft material.
  
  
  METHODS
  Postoperative speech reception thresholds, speech discrimination scores, and air-bone gap were compared with preoperative levels. Complications directly related to irradiated rib cartilage tympanoplasty were sought.
  
  
  RESULTS
  Speech reception threshold did not significantly change. Speech discrimination scores were stable or improved in all patients. Postoperative air-bone gap was < or =10 dB in 43.2% of patients and < or =20 dB in 70.3% of patients. There was a 16% complication rate regarding tympanoplasty in general. No complications unique to irradiated rib cartilage occurred.
  
  
  CONCLUSIONS
  Irradiated rib cartilage is an alternative tympanoplasty material that may save operating time, spares patients an added incision, provides results similar to other grafting material, and is safe.
