Abstract
OBJECTIVES: Short-term outcome evaluation for the correction of unilateral cleft lip deformity with a new technique. METHODS: Forty-four patients with unilateral cleft lip deformity were included in the study and in which the orbicularis oris muscle was reconstructed to achieve the optimal force balance of reconstructed orbicularis oris. The photometric two-dimensional indexes, including the philtrum oblique angle and asymmetry ratios (lip height, lip width, vertical distance from the white roll to the vermilion bottom at the Cupid's bow point, and vertical distance from the Cupid 's bow points to facial midline), were employed to measure and evaluate the outcome. RESULTS: Several indexes showed statistically significant difference, and they included the philtrum oblique angle, asymmetry ratio of the lip height, and asymmetry ratio of the vertical distance from the white roll to the vermilion bottom at Cupid ' s bow points (P<0.05). CONCLUSIONS: The results suggested that the new muscle reconstruction technique can significantly improve the short-term outcome of the correction of unilateral cleft lip deformity.
