A retrospective study of 240 stapedectomies for otosclerosis performed in a teaching department during the last 10 years was done. The results and complications in patients operated on by residents and faculty were compared. Strict criteria for evaluating the surgical outcome were used. "Satisfactory" results obtained by residents during their entire training (79 per cent) were significantly poorer (P greater than 0.05) than those achieved by the faculty (90 per cent). In the second period of residency, however, the residents' success rate (89 per cent) was equal to that of the faculty. There was no statistically significant difference in the complication rate between residents and faculty. Two essential conditions are responsible for good stapedectomy results by residents: experience with sufficient numbers of patients requiring middle-ear surgery (including otosclerosis and chronic middle-ear disease) and close supervision by the faculty in the operating room.
对过去10年在某教学科室进行的240例耳硬化镫骨切除术进行了回顾性研究。比较了住院医师和教员手术患者的结果及并发症。采用了严格的手术结果评估标准。住院医师在整个培训期间获得的“满意”结果（79%）明显低于教员获得的结果（90%）（P>0.05）。然而，在住院医师培训的第二阶段，住院医师的成功率（89%）与教员相当。住院医师和教员之间的并发症发生率无统计学显著差异。住院医师镫骨切除术取得良好结果有两个基本条件：有足够数量需要中耳手术（包括耳硬化和慢性中耳疾病）患者的经验，以及教员在手术室的密切监督。
