Medial Sural Artery Perforator Flap Aided by Ultrasonic Perforator Localization for Reconstruction After Oral Carcinoma Resection

The MSAPF is a good alternative for postsurgical reconstruction of oral carcinoma because of its anatomic structural stability, suitable thickness, minimal donor-site scar, and ideal functional recovery after surgery. Preoperative vascular ultrasonic localization is a feasible and advantageous method for preoperative mapping of the MSAP because of its high accuracy.
