封闭负压引流技术治疗口腔颌面间隙感染的临床应用

目的 评价封闭负压引流（VSD）技术持续负压引流并生理盐水持续冲洗治疗口腔颌面间隙感染的疗效。方法 对116例颌面间隙感染病例进行回顾性分析,收集患者临床资料,比较常规手术切开引流（传统治疗组,58例）和手术切开VSD（VSD组,58例）这2种治疗方法的治疗效果。结果 VSD组患者的住院时间、白细胞计数、瘢痕长度、换药次数、疼痛程度均低于传统治疗组,张口改善度优于传统治疗组（P<0.05）。结论 封闭负压引流技术是治疗口腔颌面间隙感染的更为有效的一种方法。

Clinical value of vacuum sealing drainage in the treatment of oral and maxillofacial space infection

Objective This study aims to observe the efficacy of vacuum sealing drainage (VSD) by continuous negative pressure drainage and saline irrigation in the treatment of oral and maxillofacial space infection. Methods Retrospective analysis was conducted on 116 cases of maxillofacial space infection, and clinical data were collected to compare the thera-peutic effects of routine incision with drainage treatment (traditional treatment group, 58 cases) and VSD treatment (VSD group, 58 cases). Results The length of hospital stay, white blood cell count, scar length, frequency of dressing change, and pain degree of patients in the VSD group were all lower than those in the traditional treatment group. Moreover, the improvement degree of mouth opening in the VSD groups was better than that in the traditional treatment group (P<0.05). Conclusion VSD is a more effective method for the treatment of oral and maxillofacial space infection.
