目的：观察局部注射地塞米松预防下颌第三磨牙阻生拔除术后面部肿胀度和疼痛程度的临床疗效。方法：筛选2010年3月至2014年2月102例18～25周岁的、需拔除的下颌阻生第三磨牙患者，分成实验组和对照组，每组51例，实验组在拔牙区软组织内局部注射地塞米松。术后第1天分别对两组患者观察面部肿胀度和测试疼痛程度。结果：实验组患者拔牙术后面部肿胀率明显低于对照组。术后两组的疼痛程度没有显著差异。结论：术前术区局部注射地塞米松，可以有效减少下颌阻生第三磨牙拔除术后的面部肿胀程度，有较好的临床疗效。

Objective:To investigate the effects of dexamethasone injection preoperatively on facial swelling and pain af-ter lower impacted third molar surgery. Method:102 mandibular impacted third molars needed surgical extraction were di-vided into experimental group and control group from March 2010 to February 2014. Patients in experimental group received partially injection of dexamethasone on soft tissue before the surgical extraction. Clinical assessment of the pain and facial swelling was measured at first day postoperatively. Result:Facial swelling score were lower obviously in experimental group, but there were not significant differences in assessment of the pain between experimental group and control groups. Con-clusion:With partially injection of dexamethasone on soft tissue before the surgical extraction,it is effective to improve the complication of facial swelling after mandibular impacted third molar surgery.
