• A study comparing two instruments used in laryngeal examinations was conducted in a medical school in an attempt to assess the educational use of each instrument. Thirty-nine students rotating through two surgery clerkship programs were randomly assigned to two groups and were evaluated on their ability to perform the examination correctly and to identify eight laryngeal structures using both the traditional head mirror and the right-angle laryngeal telescope. Instructional strategy was identical for both groups, with the order of instruction and evaluation serving as the independent variable. Student performance on the telescope examination was significantly better, regardless of order effect. Most students had little difficulty identifying laryngeal anatomy with the telescope. However, the pyriform sinus and posterior commissure were difficult to identify, and the anterior commissure was virtually unidentifiable by the head mirror examination.
