改良三角瓣对下颌第三磨牙拔除术后并发症的影响及其临床应用

Influence of improved triangular flap on postoperative complications after mandibular third molar removal and its clinical application

目的通过对比改良三角瓣与传统三角瓣对下颌近中阻生第三磨牙拔除术后并发症的影响,探讨改良三角瓣的临床应用。方法选取110例门诊就诊需要拔除第三磨牙的患者,随机分为2组:改良三角瓣组和传统三角瓣组,记录患者术后2、7 d的疼痛程度、肿胀程度和张口受限程度,进行组间比较。结果术后2 d,改良三角瓣组的肿胀程度(Z=-3.432)和张口受限程度(t=19.188)均小于传统三角瓣组,其差异有统计学意义(P<0.05),但术后7 d无此差别(P>0.05)。而在疼痛程度方面,两者在术后2 d和术后7 d均未看到明显差异(P>0.05)。结论与传统三角瓣相比,改良三角瓣早期并发症更轻,熟练掌握后操作更容易,值得推广。

Objective This study evaluated the effects of two different flap designs（improved triangular flap and traditional triangular flap） on mandibular third molar post-surgical complications, and to investigate the clinical application of the improved triangular flap. Methods A total of 110 patients were selected in our hospital between October 2015 and April 2016, and were randomly divided into two groups（improved triangular flap group and traditional triangular flap group）. Data of postoperative swelling, pain and trismus were recorded 2 and 7 days after surgery, and compared between the two groups. Results There were less severe facial swelling（Z=-3.432, P〈0.05） and trismus（t=19.188, P〈0.05） in improved triangular flap group after two days compared with that in the traditional triangular flap group. However, no significant differences were found in the two groups（P〉0.05） after 7 days. There were no significant differences in postoperative pain after 2 and 7 days between two flap designs（P〉0.05）. Conclusion The improved triangular flap is more beneficial to the early recovery of patients after surgery and easier to master for surgeons.
