Upper Lip Fat Grafting Using the Anatomical Subunit and Fat Compartment Principles Improves Lip Cant and Symmetry in Patients With Unilateral Upper Lip Asymmetries.

摘要: BACKGROUND Fat grafting is a widely adopted method for reconstructing upper lip asymmetries. However, most surgical techniques are difficult to reproduce, and none follow anatomical principles. OBJECTIVES The aim of this study was assess the clinical outcomes contour asymmetry cant correction by fat using subunit compartment METHODS A prospective analysis conducted 113 consecutive patients who underwent principles management and/or (volumetric) asymmetry. Quantitative photogrammetric symmetry measurements were blindly performed preoperatively at 3 12 months postoperatively. panel assessment (by 8 blinded external plastic surgeons laypersons) obtained grade qualitative symmetry. Bivariate multivariate analyses identify independent variables associated with 12-month postoperative change. RESULTS There significant (all P 0.05) from Parry-Romberg syndrome negatively (P < CONCLUSIONS Anatomical grafting, principles, improves in unilateral
