摘要
目的:探讨口内或口外2种路径进行微型钛板固定术治疗下颌角不稳定性骨折的临床效果。方法:通过口内(n=20)和口外(n=26)路径对46例下颌角不稳定性骨折进行微型钛板固定术,术后观察治疗效果。结果:口外组有2例切口感染,其中1例发展为骨髓炎经过拔牙及取出钛板后愈合;口内组有2例口内切口感染,经过局部冲洗填碘仿纱条后愈合;2组其余病例术后切口均I期愈合。经过3-12个月随访,2组病例张口度大于35 mm,无咬合紊乱,骨折对位良好,无移位。口外组病例均留有瘢痕。结论:2种方法治疗下颌角不稳定性骨折,均达到稳定固定的效果。
Objective:To evaluation of the treatment of unfavourable mandibular angle fracture by internal fixation with two different approachs.Methods:46 patients with unfavourable mandibular angle fracture were treated by internal fixation with titanium miniplate through transoral approach group(n = 20) and extraoral approach group(n =26) respectively.Postoperative clinical and radiological data including wound healing,difficulty in function and malocclusion were analysed 10 days,3 months and 6 months after operation.Results:Postoperative infection occurred in 2 cases in extraoral group,and 1 of them developed as ostomylitis which recovered gradually in 1 year.Surgical site infection was observed in 2 cases in transoral approach group,which was resolved with appropriate course of antibiotics and wound care.Conclusion:Unfavourable mandibular angle fracture can be effectively treated by titanium miniplate via intraoral or extraoral approach.
