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.
