摘要： 目的: 评价改良型往复锯在下颌角成形术中的应用效果,为临床手术器械选择提供参考。方法: 回顾性分析2021年3月—2024年1月于贵州医科大学附属口腔医院接受下颌角成形术的16例双侧下颌角肥大患者的临床资料。所有患者均采用改良型往复锯进行截骨,采用螺旋CT测量术前及术后下颌角角度、下颌对称性（双侧下颌角点至面中部平面水平差值）、下面部宽度（双侧下颌角点距离）、下颌后升支高度（髁顶点至下颌角点距离）等数据,随访患者满意度及术后并发症。结果: 术后各项指标较术前均显著改善,下颌角角度由 105.99°±4.67°增至113.87°±3.80°（P<0.05）,下颌对称性由（4.21±3.26）mm 提升至（2.11±1.59）mm（P<0.05）,下面部宽度由（98.23±7.88）mm 降至（96.09±8.25）mm（P<0.05）,下颌后升支高度由（62.32±5.26）mm降至（44.47±4.97）mm（P<0.05）。随访6~12个月,未观察到软组织下垂或髁突骨折等严重并发症,患者术后满意度显著高于术前（P<0.05）。结论: 改良型往复锯用于下颌角成形术,可有效改善下颌角角度、对称性及下面部宽度,显著降低软组织下垂风险,并发症少且患者满意度高,有望成为该手术的优选器械。

Abstract: PURPOSE: To evaluate the effect of modified reciprocating saw in mandibular angleplasty, and to provide a reference for the selection of clinical surgical instruments. METHORDS: The clinical data of 16 patients with bilateral mandibular angle hypertrophy who underwent mandibular angleplasty in the Affiliated Stomatological Hospital of Guizhou Medical University from March 2021 to January 2024 were retrospectively analyzed. All patients underwent osteotomy with a modified reciprocating saw. Spiral CT was used to measure data such as preoperative and postoperative mandibular angle, mandibular symmetry(horizontal difference between bilateral mandibular angle points and the midfacial plane), lower facial width (distance between bilateral mandibular angle points), and height of the posterior ascending ramus of the mandible (distance from the condylar vertex to the mandibular angle point). In addition, patient satisfaction and postoperative complications were followed up. RESULTS: All postoperative indicators were significantly improved compared with preoperative ones. The mandibular angle increased from 105.99°±4.67° to 113.87°±3.80° (P<0.05); the mandibular symmetry improved from (4.21±3.26) mm to (2.11±1.59) mm (P<0.05); the lower facial width decreased from (98.23±7.88) mm to (96.09±8.25) mm (P<0.05); and the height of the posterior ascending ramus of the mandible decreased from (62.32±5.26) mm to (44.47±4.97) mm(P<0.05). During the 6-12 month follow-up, no serious complications such as soft tissue sagging or condylar fracture were observed, and the patient satisfaction after surgery was significantly higher than that before surgery (P<0.05). CONCLUSIONS: The application of the modified reciprocating saw in mandibular angleplasty can effectively improve the mandibular angle, symmetry, and lower facial width, significantly reduce the risk of soft tissue sagging, with few complications and high patient satisfaction. It is expected to become the preferred instrument for this surgery.
