microvascular free flap

Full Definition

Microvascular free flap reconstruction involves transferring tissue from a distant site with its blood supply, requiring microsurgical anastomosis of arteries and veins at the recipient site. Common donor sites include the radial forearm, fibula, and anterolateral thigh. These procedures allow complex reconstruction of large defects following head and neck cancer resection while maintaining tissue viability. Success depends on surgical technique, patient factors, and post-operative monitoring for vascular compromise.

Usage

Usage note: Always specify the donor site when describing the reconstruction.
