项目摘要

Thermographic evaluation was made on three patients with Abbe flap. They had recieved primary repairs in infancy or childhood. The Abbe flap was inserted into the middle of the upper lip, and the vascular pedicle was separated on the 14th postoperative day in all patients.Thermographically the flap was cold for 3 postoperative days and became cold again for 2 days after the flap was separated. The temperature of the distal or proximal portion of the flap fell 1.1 to 2.0ﾟC during four or five postoperative days compared with those of the surrounding normal skin. After the flap was separated, the temperatures of the flap again fell 1.0-3.7ﾟC for 2 days at the middle and distal portion.Since cyanosis and edema were clinically noticed in the flap when there was a fall in temperature, thermography was considered to be useful not only for judgment of flap survival but also for objective and quantitative analyzes of the wound healing process.The microcirculation of flap was measured at few points of flap and surrounding normal skin by laser doppler flowmetry for blood cell velocity determination.The microcirculation at the tip of Abbe flap decreased immediately after operation, increased gradually on first postoperative day, and was at the surrounding normal skin level in a week.

对三名阿贝皮瓣患者进行热成像评估。他们在婴儿期或儿童期接受过初步修复。所有患者均于术后第14天将阿贝皮瓣置入上唇中部，分离血管蒂。热像图显示皮瓣术后3天呈冷状态，分离后2天再次变冷。术后四五天内，皮瓣远端或近端部分的温度与周围正常皮肤相比下降了1.1至2.0℃。皮瓣分离后，皮瓣中远端温度再次下降1.0-3.7℃，持续2天。由于临床上发现皮瓣在温度下降时出现紫绀和水肿，因此认为热成像不仅有助于判断皮瓣存活情况，而且有助于客观定量分析伤口愈合过程。在皮瓣及周围正常部位的几个点测量皮瓣的微循环激光多普勒血流仪测定皮肤血细胞流速。阿贝皮瓣尖端微循环术后即刻下降，术后第一天逐渐增加，一周后恢复至周围正常皮肤水平。
