摘要：Several technical variations of tympanoplasty have been reported,usually involving the type of graft and/or instruments used.Few studies have focused on the outcome of type-1 tympanoplasty specifically in teaching scenarios.We aimed to describe the results of type-1 tympanoplasty performed by residents,and to investigate potential predictive factors of surgical success.To do so,we did a retrospective analysis of medical records of patients who underwent type-1 tympanoplasty in a tertiary university hospital.We evaluated the tympanic membrane closure and audiometric outcomes during the first year of follow-up,and compared the results according to some clinical and surgical factors.130 operated ears were included in the study.The closure rate reached 84.12％after one month and 72.72％after twelve months of surgery.The mean air-bone gap was 22.98 dB preoperatively,and reached 10.55 dB after surgery.Perforation closure rates were 85％and 57.14％for those operated by endoscopic and microscopic-assisted approaches,respectively(p=0.004).The use of cartilage grafts and time without otorrhea of more than three months prior to surgery were also predictors of surgical success(p=0.002 and 0.041,respectively).Gender,age,perforation size,contralateral disease,operated side,reoperation,and degree of hearing loss did not significantly interfere with outcomes.Tympanoplasty showed good overall results when per-formed by residents,although inferior to those reported by experienced surgeons.The use of the endoscope,cartilage grafting,and longer preoperative time without otorrhea were predictors of surgical success in this scenario.
