“…Our sample size calculation was based on data from Kaplan et al . Seven participants per group (ie, experienced vs novice) were required to provide 80% power to detect a 10‐point difference in mean GRS score between novices and experienced surgeons at a 2‐sided α = 0.05.…”

Background The purpose of this study was to evaluate face and content validity of a low-cost, low-technology, non-biologic endoscopic sinus surgery (ESS) task trainer and knowledge-based curriculum followed by construct validation of the task trainer. Methods A sinus surgery task trainer and curriculum were developed. Attending otolaryngologists were surveyed regarding the utility of the task trainer and curriculum. A cross-sectional construct validation study was performed including medical students, residents, and attending otolaryngologists. Nine tasks were performed on the task trainer and graded using a global rating scale (GRS). Predictors of task trainer performance were evaluated, and spatial performance was measured. Regression analyses were performed to assess main associations. Results 100% of attendings (n=7) agreed that the task trainer accelerates the learning curve and incorporates essential ESS techniques and that the knowledge-based curriculum describes anatomical and technical knowledge germane to ESS. Twelve medical students, nine otolaryngology residents, and five attending otolaryngologists completed task trainer testing. GRS score varied by level of training after adjusting for potential confounders (slope=2.63; p=0.001). There was evidence of an association between a history of video gaming (slope=1.33; p=0.077), sports experience (slope=2.08; p=0.033), and sinus surgery simulation (slope=2.72; p=0.023) with GRS score, although not statistically significant. Conclusion This study demonstrated validity of a knowledge-based sinus surgery curriculum and low-cost, sinus task trainer supporting use in early training. Participants with prior video gaming, sports participation, and sinus surgery simulation experience perform better at baseline on the task trainer.

Objective The aim of this study was to evaluate the rate of complications and the extent of resection (EOR) of nonfunctioning pituitary adenomas by endoscopic endonasal approach (EEA) in a 15-year learning curve. Methods A total of 100 patients operated by the same surgical team were divided chronologically into two, three, and four groups, comparing differences in EOR measured by a semiautomatic software (Smartbrush, Brainlab), rate of immediate postoperative complications, and the visual and hormonal status at 6 months. Results There were no significant differences over the years in rates of postoperative complications and in visual status at 6 months. A significant linear correlation between the EOR and the number of surgeries (rho = 0.259, p = 0.007) was found. The analysis was performed in three groups because of the remarkable differences among them; the EOR were: 87.2% (early group), 93.03% (intermediate group), and 95.1% (late group) (p = 0.019). Gross total resection was achieved in 30.3, 51.5, and 64%, respectively (p = 0.017); also, the rate of reoperation and the worsening of at least one new hormonal axis were worse in the early group. Consequently, the early group had a higher risk of incomplete resection compared with the late group (odds ratio: 4.2; 95% confidence interval: 1.5–11.7). The three groups were not different in demographic and volume tumor variables preoperatively. Conclusions The first 33 interventions were associated with a lower EOR, a high volume of residual tumor, a high reoperation rate, and a higher rate of hormonal dysfunction. We did not find differences in terms of postoperative complications and the visual status at 6-month follow-up.
