The purpose of this study was to compare the two surgically assisted rapid maxillary expansion techniques, the conventional 2-segment osteotomy between maxillary central incisors versus the 3-segment osteotomy between maxillary lateral incisors and canines bilaterally. A prospective study was conducted with 19 patients. they were divided into two groups: conventional 2-segment osteotomy (ten patients) and 3-segment osteotomy (nine patients). Dental and skeletal measurements of the preoperative and postoperative cone beam computed tomography images were analyzed in the present study. Pre and post-operative periodontal probing was performed, patients` cosmetic perception was evaluated in a colored visual analogue scale, and time elapsed during surgery was measured with a regular chronometer. Homoscedaticity was confirmed by the Levene`s test, and independent samples t-test was utilized to compare means. Three segment surgically assisted rapid maxillary expansion in the current study resulted in greater transverse expansion, less molar inclination and less aesthetic compromise. Surgery took longer than conventional 2 segment SARME probably due to extra steps and surgeon’s learning curve
