gracilis muscle flap
Pronunciation: GRASS-ih-lis
A free or pedicled muscle flap from the medial thigh used for functional reconstruction, particularly in facial reanimation procedures.
Full Definition
The gracilis muscle flap is a thin, elongated muscle harvested from the medial compartment of the thigh, primarily used for functional reconstruction requiring muscle contraction. In facial reanimation procedures, the gracilis provides motor function for smile restoration in patients with facial paralysis. The flap can be innervated by the obturator nerve for pedicled transfers or reinnervated with facial nerve branches in free tissue transfer. Its advantages include reliable anatomy, minimal donor site morbidity, and excellent length for spanning facial defects. The gracilis is particularly valuable in two-stage facial reanimation protocols.
Usage
Usage note: Specify whether used for functional or bulk reconstruction and include innervation details.
