口唇形成術後の経時的形態変化 術式改良前後の結果の比較について

Abstract

Anthropometric analysis was carried out on the facial soft tissue of unilateral cleft lip (and palate) patients who underwent surgical operations for lip repair during 1986-1990, and the data were compared with those for cases operated during 1981-1986.The methods of measurement and analysis were the same as described previously (J. Jpn. Cleft Palate Assoc. No.13, p47-71, 1988). Fourteen points were selected, and the patient's face was marked. The deviation of the alar base and the columellar base was estimated by using a sliding caliper directly on the patient's face before and directly after surgery, and 2 weeks, 1 month and 3 months after the operation. The subjects consisted of 25 CL (cleft lip with or without alveolar cleft) and 30 CLP (cleft lip, alveolus and palate) patients.The results were as follows:1. The position of the columellar base was nearer the midline than that in the previous cases 3 months after the operation.2. In patients with narrow cleft width, both lateral nasal alae were shifted in a more symmetrical position than in previous cases.3. The downward deviation of the alar base on the cleft side was corrected into a symmetrical position 3 months after the operation.4. The marginal length of the naris on the cleft side was longer than that of the noncleft side 3 months after the operation. But the difference between the both sides was less than that in previous cases.
