Indian Journal of Plastic Surgery, 2022 AbstractA propeller flap is an islanded flap that reaches the recipient site through an axial rotation around its vascular axis. The degree of rotation varies from 90 degrees to 180 degrees. It is a highly reliable local reconstructive option. These flaps are simple, single-stage, easy to harvest, and not constrained by routine length-to-width ratios ...
