Surgical Innovation in Facial Reconstruction after Tumors Resection: Challenge of Keystone Perforator Flap

Abstract: Background: Reconstruction of facial defects after tumor excision requires reliable coverage while preserving contour, symmetry, and important functional landmarks. The keystone perforator flap provides local tissue with a broad vascular base, but its configuration must be tailored to tissue laxity and the variable anatomy of facial subunits.
