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 ≥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 ≤0 dB in 43.2% of patients and ≤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.
