Learning curve of septoplasty procedure

Abstract

Objectives: The aim of this study was to investigate possible relationship between surgical experience and septoplasty-related dataand to determine the learning curve based on surgery duration.Patients and Methods: The first 60 septoplasty patients of four Ear, Nose and Throat residents who completed an 18-monthresidency training in our clinic between August 2015 and December 2017 were included in the study. A total of 240 patients(155 males, 85 females; mean age 32.8±10.6 years; range, 17 to 60 years) were evaluated. The first 10 patients were groupedas Group A, 11-20 patients as Group B, 21-30 patients as Group C, 31-40 patients as Group D, 41-50 patients as Group E, and51-60 patients as Group F. The patients’ files were retrospectively reviewed to obtain information on demographics, postoperativehospital stay, complications, revision operation requirements, and operation time. The mean operation time was calculated. Durationof surgery was used to evaluate the maturity of surgical skills.Results: The mean operation time was 60.0±17.3 min. The mean operation times of the patients in Group A and Group B weresignificantly longer than that of the patients in Group C, Group D, Group E, and Group F. There was no significant difference betweenthe groups in terms of length of hospital stay, complications, and revision rates.Conclusion: As the surgeon's experience increases, the operation time decreases, and after 20 patients, it reaches the plateaulevel. Based on these data, it can be concluded that ENT residents should practice more than 20 patients to learn the septoplastyprocedure sufficiently.
