目的 :比较2种不同切开翻瓣法拔除水平阻生下颌第三磨牙的临床效果。方法 :选取水平阻生下颌第三磨牙患者400例,随机分为A、B 2组。A组200例,采用远中切口翻瓣法;B组200例,采用常规角形切口翻瓣法,观察2组病例拔牙时间、干槽症发生率、术后疼痛、面部肿胀、开口受限等情况,应用SPSS 13.0软件包对数据进行统计学分析。结果:A组手术时间比B组长。术后第3天,A组面部肿胀及开口受限均较B组轻,2组患者的疼痛程度无显著差异。术后第7天,2组术后疼痛、面部肿胀及开口受限无显著差异。结论:远中切口法翻瓣较角形切口法明显减少患者术后肿胀及开口受限的程度。
OBJECTIVE: To compare the clinical effects of two different incision flaps in removing impacted mandibular third molars. Methods: 400 patients with impacted mandibular third molar were randomly divided into A and B 2 groups. A group of 200 cases, using distal incision flap method; B group 200 cases, the use of conventional angular flap flap method, the observation group 2 cases of tooth extraction time, dry socket incidence, postoperative pain, facial swelling, limited openings The data were analyzed statistically using SPSS 13.0 software package. Results: The operation time of group A was longer than that of group B. On the third day after operation, the facial swelling and opening in group A were lighter than those in group B, and there was no significant difference in pain between the two groups. On the 7th day after operation, there was no significant difference between the two groups in postoperative pain, facial swelling and limited opening. CONCLUSION: Compared with the angular incision, the far-mid incision flap significantly reduces the degree of postoperative swelling and limited opening.
