The groups were matched by age, sex, and type of surgery. Treatment duration was assessed using statistical comparisons, and perioperative and postoperative complications were analyzed using logistic and Poisson regression models adjusted for age, sex, and surgery type.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>SFA significantly reduced the total treatment duration compared to COA by eliminating the presurgical orthodontic phase (13.0 months vs. 27.67 months, P = 1.66\u00d710\u221210). The groups were similar in terms of their difficulty scores according to the ICON scale (P &amp;gt; 0.05). However, the postsurgical orthodontic phase was significantly longer in the SFA group (11.72 months vs. 8.22 months, P = 6.18\u00d710\u221213). Maxillary retrognathia was independently associated with a shorter total treatment duration, while open bite prolonged postsurgical orthodontic treatment, regardless of the surgical approach. Age was the only significant predictor of complications (P = 0.042), with older patients being at a greater risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>SFA is an effective alternative to COA, offering a shorter overall treatment duration while requiring longer postsurgical orthodontic management.
