ObjectiveThis study aimed to examine the impact of trainee involvement in performing tympanoplasty or tympano-ossiculoplasty on outcomes.MethodsA retrospective analysis was performed of a prospective database of all patients undergoing tympanoplasty and tympano-ossiculoplasty in a single centre during a three-year period. Patients were divided into three primary surgeon groups: consultants, fellows and residents. The outcomes of operative time, surgical complications, length of hospital stay, and air–bone gap improvement were compared among the groups.ResultsThe study included 398 tympanoplasty and tympano-ossiculoplasty surgical procedures, 71 per cent of which were performed by junior trainees (residents). The junior trainee group was associated with a significantly longer surgical time, without adverse impact on outcomes.ConclusionTrainee participation in tympanoplasty and tympano-ossiculoplasty surgery was associated with longer surgical time, but did not negatively affect the peri-operative course or hearing outcome. Therefore, resident involvement in these types of surgery is safe.
