Extended Latissimus Dorsi Myocutaneous Flap Reconstruction of Major Head and Neck Defects

Abstract

The purpose of this article is to familiarize the surgeon with the latissimus dorsi flap and some particularly useful applications of it. This flap has proved extremely versatile, with many uses, among them immediate coverage for extensive head and neck wounds. It has been equally successful in repairing defects in both normal and irradiated tissue. The range of the arc of utilization has been exceptional, easily reaching the skull vertex from the chest wall. However, to be able to extend this flap so far requires careful dissection of the neurovascular pedicle and intimate anatomic knowledge of the posterior axilla region. This flap's muscle bulk is quite acceptable and the donor site may almost always be closed primarily. There appears to be less functional disability from sacrifice of this muscle than with pectoralis or trapezius myocufaneous flaps. Accordingly, it is ideal when much tissue is needed for single-stage coverage. Additional uses are available when flaps from other sites have failed.
