In the head rotation technique group, patients\u2019 heads were maximally rotated to the left before i-gel insertion. The primary endpoint was the first-attempt success rate. Secondary endpoints included the success rate within two attempts (using the allocated technique), time required for successful i-gel placement within two attempts, and success rate at the third attempt (using the opposite technique).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Among 158 patients, the head rotation technique group showed a significantly higher first-attempt success rate (60\/80, 75.0%) compared to the standard technique group (45\/78, 57.7%; <jats:italic>P<\/jats:italic>\u2009=\u20090.021). The success rate within two attempts was similar between the groups (95.0% vs. 91.0%, <jats:italic>P<\/jats:italic>\u2009=\u20090.326). The time required for successful i-gel placement was significantly shorter in the head rotation technique (mean [SD], 13.4 [3.7] s vs. 16.3 [7.8] s; <jats:italic>P<\/jats:italic>\u2009=\u20090.030). When the head rotation technique failed, the standard technique also failed in all cases (<jats:italic>n<\/jats:italic>\u2009=\u20094), whereas the head rotation technique succeeded in five out of the seven patients where the standard technique failed.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>The head rotation technique significantly improved the first-attempt success rate and reduced the time required for successful i-gel insertion.
