To evaluate the advantages, disadvantages, safety, and results in reconstruction of the tympanic membrane using irradiated rib cartilage.
Retrospective chart review.
A tertiary referral center.
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.
Tympanoplasty or tympanomastoidectomy using homologous irradiated rib cartilage as graft material.
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.
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.
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.
评估使用辐照肋软骨重建鼓膜的优缺点、安全性及效果。
回顾性病历审查。
一家三级转诊中心。
1993年1月1日至1996年12月31日期间在我院接受使用辐照肋软骨移植的鼓室成形术或鼓室乳突切除术且随访时间≥6个月的所有患者。
使用同种异体辐照肋软骨作为移植材料进行鼓室成形术或鼓室乳突切除术。
将术后言语接受阈、言语辨别得分和气骨导间距与术前水平进行比较。查找与辐照肋软骨鼓室成形术直接相关的并发症。
言语接受阈无显著变化。所有患者的言语辨别得分稳定或提高。43.2%的患者术后气骨导间距≤10 dB，70.3%的患者≤20 dB。总体鼓室成形术的并发症发生率为16%。未发生辐照肋软骨特有的并发症。
辐照肋软骨是一种可供选择的鼓室成形术材料，可节省手术时间，避免患者额外切口，效果与其他移植材料相似，且安全。
