带针负压引流管联合口内入路在下颌角骨折中的应用

The Application of Negative Pressure Drain with Needle on Mandibular Angle Fractures Via Intraoral Approach

目的:探讨改良带针负压引流管在下颌角区线性闭合性骨折中的应用效果。方法:选取2014年1月-2017年12月笔者科室就诊的下颌角区线性闭合性骨折患者16例,将带针负压引流管改良预弯,经面部皮肤穿刺后联合口内入路行骨折坚固内固定。术后随访6~9个月,对骨折固定可靠效果、术后并发症及咬合关系进行临床评价。结果:本组患者术后咬合关系恢复及骨折复位固定均获得良好效果,面部皮肤瘢痕不明显,无涎瘘、面瘫、耳廓麻木等并发症出现。结论:采用改良带针负压引流管经面部皮肤直接穿刺、口内入路固定下颌角骨折,具有创伤小、并发症少、面部瘢痕不明显等优点,临床效果显著。

Objective The aim of the study is to assess the clinical means of negative pressure drain with needle which was used in linear and closed mandibular angle fractures. Methods 16 patients who suffered from linear and closed fractures of mandibular angle were selected from January 2014 to October 2017,All patients were used negative pressure drain with needle to puncture facial skin directly and combined with intraoral incision to get strong internal fixation. Postoperative observation were followed up from 6 to9 months, evaluated fixation effects, postoperative complications and occlusion. Results All patients obtained good results on both postoperative occlusion and restoration of fractures, there is no complications about salivary fistula and facioplegia as well as auricle numb,facial scar is not obviously. Conclusion The methods which using negative pressure drain with needle to puncture facial skin directly and combined with intraoral incision to treat mandibular angle fractures achieved significant clinical effects with reducing the complications of salivary fistula and facioplegia as well as auricle numb without obvious scar.
