Abstract
PURPOSE: We aimed to observe the effect of prismatic glasses on improving surgeons' comfort during cleft palate surgery. MATERIALS AND METHODS: A within-subjects design was used. We included 3 oral-maxillofacial surgeons and 6 patients with complete cleft palate in the study. One group of cleft palate patients (3 complete cleft palates) was allocated to each of the 3 surgeons not wearing prismatic glasses, and another similar group of cleft palate patients was allocated to the same 3 surgeons wearing prismatic glasses. The push-back method was performed in all cleft palate patients by all surgeons. The degree of neck flexion exhibited by all surgeons was digitally video recorded. Screen-capture images of the video recordings were collected, and neck flexion in all video recordings was analyzed. All surgeons completed a questionnaire based on a visual analog scale to assess their discomfort symptoms of the neck, shoulders, and back. Operative time and bleeding volume were recorded to assess operational efficiency. RESULTS: Use of prismatic glasses significantly reduced surgeons' working time spent in pronounced neck flexion during cleft palate surgery (P < .05), and there was a statistically significant reduction in the visual analog scale discomfort scores for the neck, back, and shoulders with the use of prismatic glasses (P < .05). However, no significant difference was found in operational time (P = .337) and bleeding volume (P = .183) attributable to the presence or absence of prismatic glasses. CONCLUSIONS: An ergonomic approach to cleft palate surgery in which surgeons wore prismatic glasses improved neck, back, and shoulder comfort.
