Inspite of the advantages of these materials, certain complications has been experienced in our study with regard to the resorption and degradation of the material which has been mentioned and explained in our article.

This study aims to evaluate efficacy of V-Y closure of upper lip incision on facial esthetics in comparison to simple continuous closure after Le Fort I advancement and superior repositioning of maxilla. Thirtyfour patients were divided in two groups i.e. V-Y closure group (group I = 17 patients) and simple continuous closure group (group II = 17 patients). The preoperative and 1 year post-operative linear and angular changes of hard and soft tissue points of groups I and II were statistically compared. Labial changes were more favourable in V-Y closure group in comparison to simple continuous closure group in both the Le Fort I maxillary movements. The upturning and forward movement of the nose were seen in both the maxillary movements but these nasal changes did not differ significantly between the groups. It was observed that the technique of V-Y closure of upper lip delivers adequate results contributing to better facial esthetics when compared to simple continuous closure.
