Sensors were attached midline between the shoulder blades and on the posterior scalp of participants and were calibrated just prior to beginning each case. Quaternion data were used to calculate neck angles during periods of active surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Endoscopic and microscopic cases included similar percentages of time in high\u2010risk neck positions, 75% and 73%, respectively, according to a validated ergonomic risk assessment tool, the Rapid Upper Limb Assessment. However, microscopic cases included a higher percentage of time spent in extension (25%) compared to endoscopic cases (12%) (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001). When examining the magnitude of average flexion and extension angles, endoscopic and microscopic cases were not significantly different.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Utilizing intraoperative sensor data, we found that both endoscopic and microscopic approaches in otologic surgery were associated with high\u2010risk neck angles, which can result in sustained neck strain. These results suggest that optimal ergonomics may be better achieved by the consistent application of basic ergonomic principles than by changing the technology in the operating room.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ohn.226","type":"journal-article","created":{"date-parts":[[2023,2,16]],"date-time":"2023-02-16T07:24:20Z","timestamp":1676532260000},"page":"1494-1501","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Intraoperative
