Laçage de lambeau libre de grand dorsal dans le cadre des soins locaux d’un lambeau en nourrice du cuir chevelu

Abstract

Surgical treatment of large and multiple lesions of irradiated scalp may require subtotal scalp exeresis and reconstruction in two-stage free flap surgery: harvesting and placing the flap first, then scalp removing and defect covering in a second step. This strategy raises the question of how to care the flap between the two surgeries. We report an original technique of free latissimus dorsi flap lacing. A 70-year-old male, afflicted with familial cylindromatosis and treated by brachytherapy 18years ago, received a free latissimus dorsi myocutaneous flap in two-stage surgery, allowing 25×25cm pathological scalp exeresis. During first step, suture clips were fixed in two rows around the future scalp defect, in order to be used as anchors for the flap lacing. Braided wire were chosen for a better steerability, and to prevent knots untightening. Thus, the flap were placed in "anatomical" place, next to the scalp, pending secondary procedure. This situation permitted to avoid flap or pedicle compression or plication, and to ease flap care. The wires were tighten as shoelaces, allowing them to be undone and done as desired. The two-stage free latissimus dorsi flap reconstruction of scalp large defect permitted us to assess the flap reliability before final reconstruction. The lacing solution allowed us regular local care and convenient flap handling, while favoriting its optimal placing next to its future location.
