Ergonomics in Craniofacial Surgery: Can We Do Better? A Quality Improvement Study

Abstract

Objective: Many plastic surgeons experience musculoskeletal strain and injury from poor ergonomics during surgery. This is associated with reduced performance, shortened careers, and decreased quality of life. This study compared the ergonomics of the conventional operating table headrest and the Mayfield headrest in craniofacial surgery. Methods: A prospective cohort study of patients undergoing craniofacial operations between November 20, 2022 and April 26, 2023, within a single craniofacial surgeon’s practice. The authors obtained data on the total duration of the operation and Rapid Entire Body Assessment (REBA) scores for the primary surgeon and assistant. Results: Four operations (mean: 147 ± 60.9 min) were included in the regular headrest group, and 8 in the Mayfield headrest group (mean: 61±53.4 min). Four hundred fifty-five regular headrest time points and 851 Mayfield time points were recorded. Eight hundred thirty-five regular headrest time points and 538 Mayfield time points were recorded. The mean REBA score for the regular headrest was 5.79 ± 1.9, which was higher than the Mayfield (5.01 ± 2.0; P < 0.0001). Subgroup analysis showed the mean REBA score for the primary surgeon (5.89 ± 2.0) was higher than the assist (5.48 ± 1.6) in the regular headrest group (P < 0.0001), whereas the converse was true for the Mayfield headrest (primary surgeon: 4.67 ± 1.8, assist: 5.65 ± 2.15, P < 0.0001). Conclusions: Ergonomic scores were better using the Mayfield headrest than the regular headrest. The primary surgeon scored better with the Mayfield headrest, whereas the assists had better scores with the regular headrest.
