Analysis of Incision Effects on Upper Lip Height and Thickness After Maxillary Surgically Assisted Expansion: A Randomized Clinical Trial

Maxillary circumvestibular incision causes significant shortening of the UL and thinning of the uppermost portion when using a #15 scalpel blade or electrocautery. However, there is no difference in UL dimensional changes when using either technique for maxillary circumvestibular incision.
