“…In the past there has been various training methods devised for nonpatient training of surgeons for FESS, from simplified training models 7–9 to virtual reality (VR) applications 10–12 and cadaveric dissections 13 . Simplified models and specified skills training contributes to the acquisition of basic surgical techniques and simple endoscopic maneuvers of surgical instruments 7–9 . However, these skills do not cover the skills and knowledge necessary to complete complex sinus surgery.…”

Background: The purpose of this study was to find a utility of a newly developed 3D-printed sinus model and to evaluate the educational benefit of simulation training with the models for functional endoscopic sinus surgery (FESS).Material and methods: Forty-seven otolaryngologists were categorized as experts (board-certified physicians with ≥200 experiences of FESS, n = 9), intermediates (board-certified physicians with <200 experiences of FESS, n = 19), and novices (registrars, n = 19). They performed FESS simulation training on 3D-printed models manufactured from DICOM images of computed tomography (CT) scan of real patients. Their surgical performance was assessed with the objective structured assessment of technical skills (OSATS) score and dissection quality evaluated radiologically with a postdissection CT scan. First we evaluated the face, content, and constructive values. Second we evaluated the educational benefit of the training. Ten novices underwent training (training group) and their outcomes were compared to the remaining novices without training (control group). The training group performed cadaveric FESS surgeries before and after the repetitive training.Results: The feedback from experts revealed high face and content value of the 3Dprinted models. Experts, intermediates, and novices demonstrated statistical differ-

“…All students received training, and skills were evaluated only on the sinus trainer. [12][13][14] Harbison et al 20 evaluated task performance of 10 medical students and 10 Otolaryngology residents on a nonbiologic sinus task trainer model followed by cadaveric dissection. However, a control group was not used in this study.…”

“…Finally, these studies have evaluated skills learned from endoscopic simulators using these same simulators, instead of separate models that may better mimic operating on patients. [9][10][11][12][13][14][15][16][17][18][19][20][21][22] The purpose of this study is to further investigate the effects of simulation on medical student task performance with the addition of a control group and a final skill evaluation on human cadavers. The aims of this study were to (1) describe a novel low-fidelity ESS simulation experience for medical student education, (2) evaluate the effect of this simulation on procedural and psychomotor competence of medical students-true surgical novices-performing endoscopic tasks on human cadavers, and (3) assess student perceptions of the simulation experience.…”

Background Interest in endoscopic simulation is increasing. Past studies have used virtual reality or nonhuman models or residents with varying experience. Our aim was to evaluate the effect of simulation on procedural and psychomotor competence of medical students—surgical novices—performing endoscopic tasks on human cadavers and assess student perceptions. Methods Students (n = 22) completed a baseline sinus model skill evaluation graded by 2 blinded Rhinology fellows. Intervention and control groups with equal baselines were assigned. Intervention students practiced endoscopic tasks on the model for 45 minutes minimum over 2 weeks. All students reviewed sinus anatomy/disease and sinus surgery materials. The final cadaver evaluation was similar to the baseline. Fellows graded students on anatomy identification (sinuses, turbinates), psychomotor (navigation, camera alignment, instrument handling), and timed procedural (sinus object retrieval) skills, confidence, and instructability via fellow-guided frontal balloon placement. Results Participants included 16 males (72.7%) and 6 females (27.3%). Intervention and control groups contained 10 (45.4%) and 12 (54.6%) students, respectively. Intervention group final “Total Psychomotor” scores were higher (10.1/15 vs 7.8/15, P = .0231). “Surgical confidence” was 3.3/5 versus 2.5/5, and “Instructability” was 3.9/5 versus 3.4/5 in intervention versus control groups, respectively ( P < .050). Multivariate regression analysis demonstrated superior psychomotor skills, navigation, and confidence in the intervention group ( P < .036). Activity perception scores were higher in intervention students versus controls, 26.13 versus 18.36/40 ( P = .022). Conclusion In surgical novices, endoscopic simulation leads to superior endoscopic navigation and task performance in cadavers. This simulation presents a novel method for incorporating Otolaryngology simulation in medical student education.

“…Research has shown that skills acquired during ESS simulation training translate into improved performance in the operating room. The low‐cost sinus surgery task trainer developed by Harbison et al demonstrated that participants completing a simulation‐based education improved their ESS checklist scores for cadaveric uncinetomy and maxillary antrostomy . Residents who trained with the virtual reality‐based Madigan ES3 system were quicker and made fewer mucosal injection errors during in vivo ESS procedures and completed the tasks significantly faster compared to residents without Madigan ES3 training experience; however, injections are different than the actual performance of ESS.…”

Objective: Assess construct validity of a low-cost medium-fidelity silicone injection molded model task trainer for endoscopic sinus surgery (ESS) training.Methods: Fellowship-trained rhinologists, otolaryngology attendings, and otolaryngology residents at various levels of training performed sinus endoscopy and seven procedures on the model. Construct validity was evaluated by comparing novice to various levels of experienced performance using a validated checklist.Results: Thirty-two subjects participated in this study. Otolaryngology attendings and postgraduate year (PGY) 3 to 5 otolaryngology residents significantly outperformed PGY 1 to 2 otolaryngology residents on most tasks in the task-specific checklist.Conclusions: This study demonstrated the construct validity of the low-cost medium-fidelity ESS model.
