自制穿颊器在微创治疗下颌骨骨折中的应用

目的：观察口内切开和经颊小切口穿刺手术入路处理下颌骨角部和升支部骨折，并月小钛板坚固内固定的疗效。方法：对21例下颌骨角部和升支骨折患者，经口内切口联合颊部小切口穿刺复住内固定。结果：用口内切开辅助经颊小切口入路行下颌骨内固定术，有效地减少了术后面瘫和面部瘢痕的出现。没有术后感染需切开引流或取出固定物的病例。结论：通过口内切开辅助颊部小切口入路行坚固内固定，适用于单纯下颌骨角部和升支部骨折的病例。

Treatment of mandibular fractures with the tramsbical trochar instrumentation

Objective To observe the treatment effect of using screwed miniplates through an intraoral and transoral approach for patients with angle and ramus fractures, Nethods 21 cases of mandibular angle and ramus fractures were treated by screwed miniplates placed through an intraoral incision with transbuccal mini-incision.
