“…Researchers modified this approach to overcome this problem, four horizontal and two vertical planes were anatomically oriented to segment the facial surface into ten regions. 20 The method provided additional regional information without the need for landmarking. However, the segmentation process did not reflect true anatomical regions of the face.…”

Abstract:Aim; This study was carried out to provide a comprehensive description of facial changes following Le Fort I osteotomy and introducing a novel tool for facial anthropometric analysis. Materials & 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 which were captured one month before surgery and 6 to 12 months postoperatively. Two types of the analysis were applied in this study, the Euclidian corresponding

“…Soft tissue responses following orthognathic correction are influenced by several factors [1][2][3]. It was necessary to account the degree of overjet and overbite for predicting the final soft tissue appearance after orthognathic surgery [1].…”

“…It was necessary to account the degree of overjet and overbite for predicting the final soft tissue appearance after orthognathic surgery [1]. Facial soft tissues are not only influenced by hard tissue changes but also by soft tissue thickness [2,3]. The upper and lower incisors correlated with the soft tissue after reduction of mandibular prognathism, and horizontal changes in lip morphology, respectively [4,5].…”

“…In addition, the position of the menton was correlated with the form of the lip [9]. From the previous reports, these 10 factors are most likely correlated with soft tissue changes after orthognathic surgery [1][2][3][4][5][6][7][8][9]. However, the degree of influence of these parameters on soft tissue changes remains unclear.…”

“…Recently, three-dimensional analyses of pre-and postoperative changes in orthognathic patients have been carried out using X-ray computed tomography (CT) and dental cone-beam CT (CBCT) instead of conventional two-dimensional analysis [2,3,6,9,[12][13][14]16]. However, since these methods have been used only to determine the actual extent of soft tissue changes [2,3,6,9,13,14], few reports have analyzed postoperative three-dimensional changes using multiple regression analysis [12,16]. In order to predict the soft tissue changes after surgery, it is necessary to elucidate the factors that influence the three-dimensional changes.…”

Aim It is widely known that orthognathic surgery affects changes in facial soft tissue morphology. However, the effect of orthognathic surgery on facial expression remains to be verified. The purpose of this study was to examine the pros and cons of the effects of orthognathic surgery on facial expression in skeletal Class III patients. Methods Fifteen patients (5 males, 10 females) were captured pre‐surgery and at 6 months' post‐surgery using Kinect camera while performing facial soft tissue movements (opening mouth, smiling, and blowing). The three‐dimensional coordinates, amount of movement, and velocity of the eight facial soft tissue landmarks during motion were obtained. As controls, 15 Japanese healthy volunteers with Class I occlusion were included. Results Differences in the three‐dimensional coordinate values during movement were confirmed, and there were some landmarks in the lower face region of the preoperative patient that showed significant differences compared with the control. Total amount of movement and velocity of Pogonion during smiling were significantly smaller than those of the control group, but there was no significant difference between the control and postoperative groups at any landmarks after surgery. It was suggested that patients with skeletal Class III may have limited movement in some movements, and it was confirmed that with orthognathic surgery, the aspect of movement would be similar to that of the control. Conclusions Orthognathic surgery may be beneficial to the facial muscles without limiting facial movements.
