A relatively high complication rate in surgery for ear canal exostoses is reported in the literature. It was found of interest to review our long-term results of surgery in ear-canal exostosis, using case-report review and clinical and audiological re-evaluation. Nineteen of 26 patients, 24 ears, operated in the 20-year period 1976-1996 were re-evaluated, mean time from surgery 7.3 years. All patients were found preoperatively to have occluding ear canal exostoses with a variety of related symptoms, all were in most cases operated via the trans-canal approach. At the re-evaluation all patients were completely free of symptoms, even though exostosis remnants were found in 19 of 24 operated ears. The complication rate was 12.5%. In conclusion, in order to avoid the complications found in this material as well as in other reports a less radical removal of exostoses is proposed.
文献报道耳道外生骨疣手术的并发症发生率相对较高。通过病例报告回顾以及临床和听力学重新评估，对我们耳道外生骨疣手术的长期结果进行回顾很有意义。在1976年至1996年这20年期间接受手术的26例患者（24耳）中，对19例进行了重新评估，距手术的平均时间为7.3年。所有患者术前均被发现有阻塞性耳道外生骨疣并伴有各种相关症状，大多数情况下均通过经耳道入路进行手术。在重新评估时，所有患者均完全无症状，尽管在24只接受手术的耳朵中有19只发现有外生骨疣残留。并发症发生率为12.5%。总之，为了避免本研究材料以及其他报告中发现的并发症，建议对外生骨疣进行不太彻底的切除。
