    Journal: Am J Otol; 1998 Mar; 19(2):141-4. PubMed ID: 9520048.
    Abstract:
    OBJECTIVE: To evaluate the advantages, disadvantages, safety, and results in reconstruction of the tympanic membrane using irradiated rib cartilage. STUDY DESIGN: Retrospective chart review. SETTING: A tertiary referral center. PATIENTS: 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. INTERVENTION: Tympanoplasty or tympanomastoidectomy using homologous irradiated rib cartilage as graft material. MAIN OUTCOME MEASURES: 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. CONCLUSION: 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.
