| Abstract |
|
Microform cleft lip is a mild expression of cleft lip.
Downward depression of the nostril rim, skin striae of the upper lip, notching of the Cupid`s bow, and deformity of the vermilion border are characteristic findings. The definition is very important to aid in selection of the operative methods. Based on our operative experiences of cleft lip, we classified microform cleft lip according to our new definition.. According to author`s classification, class I(1 case) has cleft lip nose deformity without lip deformity or with slight short lip of cleft side, class IIa(5 cases) has minimal lip deformity with blurring of cupid`s bow, vermilion notching, and skin striae with intact of orbicularis oris muscle, class IIb(12 cases) has discontinuity of the orbicularis oris muscle, class III(5 cases) has mild lip nose deformity with discontinuity of orbicularis oris muscle including Cupid`s bow deviation. In class IIb and class III, reconstruction of orbicularis oris muscle is important and we repaired it with radical operation by rotation-advancement method. A total of 23 microform cleft lip result was reviewed. We treated the clefts following the above principles according to the classification and obtained satisfactory results. |
