Force balance reconstruction of orbicularis oris in correction of unilateral cleft lip deformity / 华西口腔医学杂志

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 (@*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.

Effect of a novel rotating advancing method on reconstruction of nasal lip symmetry / 中华医学美学美容杂志

Objective@#To introduce the application of muscle reconstruction torque balance theory in the new rotating advancement method, and to evaluate the postoperative effect of this method on the nasal lip symmetry of patients with unilateral cleft lip.@*Methods@#A total of 62 patients with unilateral cleft lip were treated with two-dimensional radiography of posterior anterior position and mandibular chin position before, immediately and one-year follow-up. Five indexes representing the symmetry of lip and nose were measured by photoshop software. T test was used to compare the measurement results of each angle or distance index at different times. P<0.05 showed that there was significant difference between the two groups.@*Results@#All the patients who were treated with the technique described in this study obtained satisfactory lip and nasal symmetry immediately and one-year follow-up.@*Conclusions@#The new theory of oral muscle strength balance is a new breakthrough on the basis of the application of muscle reconstruction. It is suitable for the primary repairment of unilateral lip, and good results have been obtained.
