摘　　要：目的:观察和比较不同手术切口对拔除低位阻生下颌第三磨牙术后效果的影响。方法:选择18～30岁未萌出的双侧低位水平阻生下颌第三磨牙患者35例,随机选取患者的一侧磨牙列,采用信封切口的手术方案(A组),另一侧采用角形切口(B组)。采用同种拔牙方法拔除阻生下颌第三磨牙。观察两组患者术后第2天的反应(局部肿胀、疼痛和术后开口受限)及其他并发症发生情况,采用SPSS11.0软件包对数据进行χ2检验。结果:手术后第2天,B组术后重度肿胀的发生率显著高于A组(P<0.05)。术后开口受限程度及术后疼痛发生率A组与B组比较差异无显著性(P>0.05)。结论:不同手术切口设计与术后肿胀程度相关,信封切口术后肿胀发生程度较轻。PURPOSE： To evaluate the post-surgical effect of different incision to extract the impacted lower third molar.METHODS： Totally,35 patients with impacted lower third molar were enrolled in the study.The patients aged from 18 to 30 years.They were divided into two groups randomly.Group A underwent envelop incision,while group B underwent angled incision.The same method was used to extract the impacted molar.Post-surgical effect and complications were evaluated,the data was analyzed with SPSS11.0 softwre package for Chi-square test.RESULTS： The incidence of severe swelling in group B was significant higher than that in group A during the postoperative two days（P〈0.05）,while the difference of mouth-opening and post-surgical pain had no significant difference（P〈0.05）.CONCLUSION： Postoperative swelling is related to surgical incision,envelope incision is worth of clinical application due to the lower complications rate.
