Use of free latissimus dorsi musculocutaneous flaps in various neurosurgical disorders.

Musculocutaneous (skin-muscle) flaps have been used predominantly by plastic surgeons for a variety of reconstructive purposes. With the advent of microvascular techniques, the area to be reconstructed is no longer limited to the arc of rotation of the vascular pedicle of the muscle. Instead, the muscle and overlying skin that is best suited for the reconstructive procedure may be dissected out as a free flap, with microvascular anastomosis of an arterial supply and venous drainage to locally existing vessels. This report demonstrates the usefulness of musculocutaneous free flaps in the repair of large defects of the scalp, cranium, and dura after trauma or resection of invasive neoplasms. The authors describe the use of a latissimus dorsi free musculocutaneous flap in eight patients who would have required multiple operations to provide coverage by other techniques. There have been no major complications, and adequate repair has been accomplished, even in cases involving exposed brain.
