    Abstract:
    Introduction : The purpose of this study was to quantify anteroposterior facial soft tissue changes with respect to underlying skeletal movements after Le Fort I maxillary advancement surgery by using lateral cephalograms taken before and after the operation. Materials and Methods : The study group consisted of 20 patients (10 women, 10 men; mean age 23.4 ± 1.4 years) having a Class III skeletal deformity caused by a retrognathic maxilla. All patients were treated by Le Fort I maxillary advancement osteotomy. Lateral cephalograms were taken before and 1.6 ± 0.4 years after surgery. Results : The anteroposterior position of A-point and anteroposterior position of maxillary incisor were significantly protracted (-2.69 ± 3.34 and -2.68 ± 3.21, respectively; P < .01). The nasal anteroposterior and superoinferior positions (NASALAP and NASALSI, respectively) were significantly changed (-2.70 ± 6.81, P < .01, and -2.55 ± 5.80, P < .05, respectively) and nasal elevation and protraction were observed after Le Fort I maxillary advancement surgery. Conclusions : The changes in anteroposterior and superoinferior positions of A-point were correlated with the nasal superoinferior position (r = -0.71 , P < .05; r = 0.72, P < .05) after Le Fort I maxillary advancement surgery.
