Upper lip length after V-Y versus continuous closure for Le Fort I level maxillary osteotomy

Purpose, The purpose of this report is to document changes in lip length an d thickness after Le Fort I maxillary osteotomy by using continuous versus V-Y closure. Materials and methods, This is a retrospective analysis of 18 patients who underwent Le Fort I maxillary osteotomy. Ten patients had a single midline V-Y closure and 8 patients had simple continuous closure. Lateral cephalome tric analysis was performed, and preoperative and 12-month postoperative ch anges in lip dimensions were calculated. Lip length and thickness were anal yzed at 5 points: A-point (A), subnasale (Sn), cervical margin of incisor ( C), stomion superius (Ss) and labrale superius (Ls). The lengths from A to Sn, C lo Ls, and Sn to Ss were calculated. Results. After 12 months, there was no significant difference in lip length (P = .39) or thickness of the upper lip in its upper (P = .75) or lower (P = .19) parts, between the 2 groups. Conclusion. Lip length and width show no significant differences before sur gery versus after surgery with either closure technique after Le Fort I ost eotomy.
