Abstract
The superior labial artery mucosal (SLAM) flap is a versatile, pedicled axial flap ideally suited for mucosal lining in lower lip reconstruction. This article details the surgical anatomy and technique of the SLAM flap, highlighting its role as a standalone liner or mucosal adjunct to microvascular free tissue transfer in major composite reconstructions. Clinical success relies on preserving the submucosal venous plexus, with the axial blood supply from the superior labial artery providing resilience against prior radiation therapy. By providing pliable, homologous mucosa, the SLAM flap effectively restores oral competence and defines the vermilion border. The SLAM flap is a highly reliable option for internal lining in complex lower lip defects.
