Management of Recurrent Fibromatosis Colli with Innervated Vastus Lateralis Free Flap.

Fibromatosis colli (FC) is a fibroblastic contracture of the sternocleidomastoid muscle, often presenting as a neck mass and torticollis. The vast majority of cases resolve with conservative measures; for persistent disease, surgical tenotomy is offered. This is a case of a 4-year-old patient with large FC who failed conservative treatment as well as surgical release and ultimately underwent complete excision and reconstruction with innervated vastus lateralis free flap. We describe a novel application of this free flap for a difficult clinical scenario. Laryngoscope, 2023.
