Objective To compare the differences in incision healing between Ti-Ni memory alloy tissue anastomat and tissue adhesive produced from enbucrilate in thyroidectomy. Methods According to predetermined inclusion and exclusion criteria, 120 patients who would undergo thyroidectomy were randomly divided into 2 groups, with group A of tissue adhesive and group B of Ti-Ni memory alloy tissue anastomat. The grade of incision healing was compared and the scar type, scar width and pigmentation degree were evaluated 3 months later. Results All incisions were healed by first intention. Three months later, 105 cases were followed up, and the rate was 87.5％. There was no significant difference between the two groups on the grade of incision healing (P＞ 0.05), while the scar type, scar width and pigmentation degree were significantly different (P ＜ 0.05, respectively) . Conclusions Compared with tissue adhesive, the application of Ni-Ti memory alloy tissue anastomat to intradermal suture in thyroidectomy has cosmetological advantages such as tissue compatibility and a smaller postoperative scar.%目的 比较钛镍记忆合金组织吻合器与组织黏合剂在甲状腺手术切口愈合中的差异.方法 采用随机数字法将120例实施甲状腺手术的患者随机分为2组:A组采用组织黏合剂黏合切口,B组使用钛镍记忆合金组织吻合器皮内缝合切口.比较切口愈合等级;3个月时复诊,比较瘢痕类型、瘢痕宽度、色素沉着程度.结果 120例患者全部Ⅰ期愈合,术后3个月105例患者得到随访,随访率87.5％;2组患者的切口愈合等级沉着差异无统计学意义 (P＞ 0.05),而瘢痕类型、瘢痕宽度及色素沉着程度差异均有统计学意义 (P ＜0.05).结论 与组织黏合剂相比,在甲状腺手术中使用钛镍记忆合金组织吻合器进行皮内缝合,组织相容性好,术后瘢痕小,外表较美观.
