自创三点连线定位行下颌角截骨改善面型的效果

Clinical efficacy of mandibular angle osteotomy by three-point wiring localization on improvement of facial contour

目的探讨三点连线定位法在下颌角截骨术的临床效果。方法2021年7月至2022年4月,在四川友谊医院整形科进行下颌角长曲线截骨的美容就医者180例,男30例、女150例,年龄19~45(26.0±10.0)岁。术前双侧下颌骨CT显示基本对称,均在气管插管全身麻醉下采用三点连线定位法设计好截骨线后进行下颌角长曲线截骨术。结果180例患者双侧下颌角截骨块对称度及弧度均较好,术后无明显并发症,随访3~12个月,面形较好,双侧基本对称。结论采用三点连线定位标记下颌角长曲线截骨的方法,可确保双侧下颌角截骨的对称性、精准性、安全性均较好。

Objective To investigate the clinical application of three-point wiring localization in mandibular angle osteotomy.Methods A total of 180 patients with mandibular angle long curve osteotomy were selected in Sichuan Friendship Hospital from July 2021 to April 2022,aged 19-45(mean age 26.0±10.0)years,including 30 males and 150 females.Preoperative bilateral mandible was symmetry as CT showed,and all of them undergo operation of mandibular angle long curve osteotomy by using three-point wiring localization method under tracheal intubation general anesthesia.Results Bilateral osteotomy bone of mandibular angle was basically symmetrical in all patients,the arc of osteotomy was good,and there were no obvious complications after surgery.The postoperative follow-up was 3-12 months,and all cases had good postoperative face contour and bilateral symmetry.Conclusions Using three-point wiring localization method at operation of long curve mandibular angle osteotomy can ensure bilateral symmetry,accuracy and safety of the osteotomy.
