| Research Abstract |
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.
