Endoscopic septoplasty: Learning curve

AimsThe aim of the current study was to report the learning curve for endoscopic septoplasty for a senior surgeon already trained in endonasal sinus surgery.Material and methodsFrom November 2011 to September 2012, 100 patients were prospectively included and grouped in 5 consecutive groups of 20 by date of surgery. The primary endpoint was operative time. Intra- and postoperative complications and functional assessment were also analyzed.ResultsOperative time decreased with the surgeon's experience and became stable after 60 procedures. Operative time saving was about 10 min per 20 procedures. Mean operative time was stable between groups 4 (21.1 ± 9.6 min) and 5 (19.2 ± 8.2 min). There was a 2% rate of conversion to conventional surgery for technical problems. The number of procedures free of accidental mucosal lesion increased and became stable after 40 procedures. There was a 4% rate of residual postoperative perforation. Nasal Obstruction and Septoplasty Effectiveness (NOSE) score improved postoperatively in each group (P < 0.05).ConclusionAfter 60 endoscopic septoplasty procedures, a senior surgeon masters the surgical technique with satisfactory operative times, and a decreasing rate of intra- and postoperative complications.
