A comparative study is made of two types of flaps in semi-impacted third molar surgery and their relation to the postoperative period (pain, swelling and trismus).
Twenty-five healthy patients were subjected to surgical extraction of both semi-impacted lower third molars, located in a similar clinical and radiographic position. In 25 cases the wound was sutured using a reflection flap (healing by first intention), while in the 25 contralateral cases the conventional technique was used (simple approximation of the wound margins). Pain, swelling and trismus were evaluated, during the first week of the postoperative period.
There was lesser pain, swelling and trismus after extraction of a semi-impacted third molar when healing took place by second intention (simple approximation of the margins), than in the case of healing by first intention (flap repositioning and margin-to-margin suturing).
The postoperative course proved worse when using a reflection flap for healing by first intention than on suturing by simple approximation of the wound margins.
对阻生第三磨牙手术中两种瓣的类型及其与术后阶段（疼痛、肿胀和牙关紧闭）的关系进行比较研究。
25例健康患者接受了双侧位于相似临床和影像学位置的下颌阻生第三磨牙的手术拔除。25例患者的创口采用翻瓣缝合（一期愈合），而在对侧的25例患者中采用传统技术（创口边缘简单对合）。在术后第一周对疼痛、肿胀和牙关紧闭情况进行评估。
与一期愈合（瓣复位和边缘对边缘缝合）相比，二期愈合（边缘简单对合）拔除阻生第三磨牙后疼痛、肿胀和牙关紧闭情况较轻。
一期愈合采用翻瓣时的术后恢复情况比创口边缘简单对合缝合时更差。
