内镜辅助方型脸改型术

目的探讨内镜在方型脸改型术中的临床应用效果。方法采用口内入路，在内镜辅助下，用高速涡轮气钻截除肥大下颌角、切除部分咬肌和颊脂垫，进行方型脸的面部改型。结果本组共38例，其中男3例，女35例，年龄21～40岁。内镜完全可以清楚显示下颌升支、下颌角、下颌体下缘，视野清晰。使用高速涡轮气钻截除肥大下颌角可以更加精确和容易，且创伤小，出血少，手术时间短，感染风险低。下面部轮廓改善满意。结论内镜辅助方型脸改型术，有助于获得良好的手术效果。

Endoscopic assisted correction of square face

Objective To evaluate the clinical application of endoscopic technique in corrections of square face. Methods A total of 38 patients (age 21~40 years, 35 women and 3 men) with square face were corrected by endoscope-assisted intraoral approach and resected mandibular angle with the high-speed pneumatic drill or bulky masseter muscle and buccal fat pad. Results The use of an endoscope offered a clear view of the mandibular angle region and the application of high-speed pneumatic drill facilitated accurate and easy resection of the the mandibular angle. These patients were successfully treated for these new techniques: ruduced surgical trauma, operative bleeding and surgical time, along with a reduced risk of infection. Conclusion The endoscopic assisted correction of square face offers more satisfactory clinical results with a clear view of operation and less haematoma, risk of infection, surgical trauma and time.
