Analysis of Facial Symmetry Following Maxillary Reconstruction with the Anterolateral Thigh Flap

Residual facial asymmetry persists following ALTF maxillary reconstruction. While ALTF demonstrates limited efficacy for small defects, it moderately improves facial symmetry in extensive defects. Small defects require thinning the ALTF to improve contour and extensive defects require supplemental hard tissue support in suborbital, zygomatic, buccal, and superiolabial areas. Flap folding did not show significant symmetry improvement, and RPD provide effective hard tissue support, mitigating soft tissue collapse-related deformities, which serving as exploratory observations warranting further investigation.
