Three groups of patients, each one including 8 eyes of patients with 16 RK incisions. The first group includes eyes with the first cataract incision superiorly, the second group in the temporal area, the third group in temporal area and a precautionary stabilizing suture across the RK incision adjacent to the main tunnel. In the first group intraoperative dehiscence occurred in three eyes（37.5%）： it required immediate application of a suture. In the second group dehiscence occurred intraoperatively in two radial scars（20%）： it required immediate application of a suture. In the third group, no intraoperative dehiscences were observed. The stabilizing suture of the RK incision works safer, with a lower risk of dehiscences and less postoperative astigmatism.展开更多
目的:比较两种类型的前臂皮瓣桡侧术后前臂供区恢复的情况。方法:回顾我院44例因口腔颌面部肿瘤致术后缺损经游离前臂皮瓣修复的患者。皮瓣由同一经验丰富的医师制取。按照制取皮瓣的方法分为传统的前臂皮瓣(A组),以下简称传统组,改良...目的:比较两种类型的前臂皮瓣桡侧术后前臂供区恢复的情况。方法:回顾我院44例因口腔颌面部肿瘤致术后缺损经游离前臂皮瓣修复的患者。皮瓣由同一经验丰富的医师制取。按照制取皮瓣的方法分为传统的前臂皮瓣(A组),以下简称传统组,改良的前臂皮瓣(B组),以下简称改良组,对其术后半年、术后1年进行随访,针对制取皮瓣的手术时间、皮片面积,术后1个月内前臂供区并发症,前臂供区瘢痕及功能方面进行比较,采用SPSS 16软件进行统计学分析。结果:改良组与传统组患者皮瓣制取时间、年龄及皮片面积的P值分别为0.917,0.690,0.771。1月内术后并发症2组比较差异无统计学意义;术后半年A、B 2组在瘢痕评定量表(vancouver scar scale,VSS)中色素沉着、血管分布、柔韧性及高度、总得分方面及disabilities of the arm,shoulder and hand questionnaire(DASH)的功能及症状、总得分方面差异无统计学意义;术后1年A、B 2组在上述方面差异也无统计学意义。结论:改良组与传统组在供区恢复方面无差异。但改良组避免了传统组需开辟第三术区的问题,减少了手术创伤、患者的痛苦与额外的瘢痕。展开更多
