内镜辅助下颌升支和髁颈骨折内固定

目的探讨内镜在下颌升支和髁颈骨折内固定术中的临床使用价值。方法11例下颌升支和髁颈骨折患者在内镜辅助下，用微型侧壁电钻和螺丝刀，经口内小型钛板内固定。结果全部病例面部皮肤均无明显手术瘢痕。术后1—15个月复查曲面断层X线片或螺旋CT三维重建，下颌骨骨折对位良好，10例恢复正常咬合关系，1例前牙轻度开猞，2例多处骨折患者术后轻度张口受限。结论在内镜辅助下行下颌升支和髁颈骨折内固定，可以避免损伤面神经，并避免遗留颌面部皮肤瘢痕，创伤小，效果好。

Endoscopy-assisted internal fixation of ramus and subcondylar fracture

Objective To investigate clinical application of endoscopy-assisted internal fixation of ramus and subcondylar fractures . Methods In 11 patients with mandibular ramus and subcondylar fractures, endoscopy-assisted internal fixations with titanium plates were performed using micro-angular drill and screwdriver. Results All of the patients showed no visible facial scars . Orthorpantography and three dimensional reconstructions of spiral CT scan demonstrated that all fractures were healed 1 to 15 months after operation, Slight malocclusion existed in 1 case and slight limited mouth opennings were found in 2 cases, Conclusions Endoscopy-assisted internal fixation of mandibular ramus and subcondylar fracture avoided visible facial scars and the risk of facial nerve damage, it is , therefore, a minimally invasive and effective procedure.
