The purpose of this study was to evaluate outcomes of simultaneous correction of the hard- and soft-tissue facial asymmetry with face lift procedure using a resorbable fixation device (Endotine Ribbon; Coapt Systems, Palo Alto, CA) during bimaxillary orthognathic surgery in cases with severe facial asymmetry. The samples consisted of 8 patients (mean age, 23.3 [SD, 4.4] years; 8 skeletal class III and 2 class II malocclusion) who received bimaxillary orthognathic surgery and a face lift procedure using a resorbable fixation device. Preoperative cephalometric evaluation of the maxillary occlusal plane cant and chin point deviation and data on surgical movement, site, time, and difficulty of face lift procedure were collected at 1 week before operation and during operation procedure. The amounts of lip cant between preoperation and postoperation were compared. Pain, stability of fixation, adverse effects, relapse, and patients' and surgeon's satisfaction were evaluated at 6 months after operation. Initial and final amounts of the lip cant were 4.15 (SD, 0.53) and 0.80 (SD, 0.48) mm (correction rate, 76.8%). The face lift procedure took 28.4 (SD, 3.3) minutes without difficulty. There were no severe complications such as hematoma, facial nerve injury, and postoperative scar. By the patients' and surgeon's view, all had satisfactory jowl elevation, lip canting correction, and achievement of the soft-tissue symmetry without evidence of recurrent asymmetry or loss of fixation. If the face lift procedure using a resorbable fixation device is done with proper vector control during orthognathic surgery, the hard- and soft-tissue facial asymmetry can be corrected simultaneously with satisfactory outcomes.
本研究的目的是评估在严重面部不对称病例的双颌正颌手术中,使用可吸收固定装置(Endotine Ribbon;Coapt Systems,加利福尼亚州帕洛阿尔托)进行面部提升手术同时矫正面部软硬组织不对称的效果。样本包括8例患者(平均年龄23.3 [标准差,4.4]岁;8例骨骼Ⅲ类错颌和2例Ⅱ类错颌),他们接受了双颌正颌手术和使用可吸收固定装置的面部提升手术。术前对头影测量上颌咬合平面倾斜度和颏点偏差进行评估,并在术前1周和手术过程中收集面部提升手术的手术移动、部位、时间和难度数据。比较术前和术后的唇倾斜度。在术后6个月评估疼痛、固定稳定性、不良反应、复发情况以及患者和外科医生的满意度。唇倾斜度的初始值和最终值分别为4.15(标准差,0.53)和0.80(标准差,0.48)mm(矫正率76.8%)。面部提升手术耗时28.4(标准差,3.3)分钟,无困难。未出现严重并发症,如血肿、面神经损伤和术后瘢痕。从患者和外科医生的角度来看,所有患者的下颌赘肉提升、唇倾斜度矫正以及软组织对称性的实现均令人满意,未出现复发性不对称或固定丢失的迹象。如果在正颌手术期间使用可吸收固定装置进行面部提升手术时进行适当的矢量控制,则可以同时矫正面部软硬组织不对称,且效果令人满意。
