Teaching and assessing endoscopic sinus surgery skills on a validated low-cost task trainer.

Objectives/hypothesis: To evaluate a previously validated low-cost sinus surgery task trainer as a means of acquiring basic endoscopic sinus surgery skills and as an objective structured assessment of technical skills (OSATS) to determine procedural competency.

Study Design: Prospective blinded study.

Methods: Medical students (N = 52) with no sinus surgery experience learned to perform nasal endoscopy and five specific sinus surgery tasks using the validated task trainer.

Objective: To assess the face, content, and construct validities of a low-cost sinus surgery task trainer in acquisition of skills for endoscopic sinus surgery.

Study Design: Prospective validation study.

Setting: Tertiary academic center.
