Aim: This study was carried out to provide a comprehensive 3D description of facial changes following Le Fort I osteotomy and introducing a novel tool for facial anthropometric analysis.Materials and methods: This study was carried out on 33 patients who had had Le Fort I maxillary advancement with or without posterior vertical impaction. The investigation was conducted on the CBCT images taken one month before surgery and 6-12 months postoperatively. Results:The average anteroposterior surgical movement advancemnt of the maxilla was the advancement of 5.9mm±1.7mm with minor anterior and posterior vertical maxillary impaction of 0.1mm±1.7mm and 0.6mm±1.45mm respectively. There were a distinctive forward soft tissue movements combined with a marked lateral expansion at the upper lip and paranasal regions; the right and left alar curvatures and the columella showed a marked upward movement. The effect on the nose was limited to the widening and advancement of the nostrils as well as the base of the nose (Subnasale and alar base) region with a minimal forward change but a noticeable upward movement at the nasal tip. The changes at the cheeks were minimal. Conclusions: Le Fort I advancement osteotomy widened the mid-face and upper lip, compressed and widened the nostrils and shortened the lower lip. The effect of surgery may extend to the chin and lower lip secondary to the maxillary impaction.
