Free composite osseomyocutaneous flap of latissimus dorsi, serratus anterior and rib for oromandibular reconstruction

Abstract 

A wide variety of osseomyocutaneous free flaps for mandibular reconstruction has been described. The flap made up of latissimus dorsi, serratus anterior and rib (LSRF), , can provide vascularized skin, muscle, bone and cartilage on a single thoracodorsal vascular pedicle and is useful in some circumstances, i.e., large soft tissues defects. In this paper, we describe two cases in which the flap was chosen for reconstruction of the mandible, cheek and intraoral mucosa, following major ablation of malignant tumours. In our experience, this flap is excellent for soft tissue repair and fulfils the basic requirements of bony restoration. Moreover, the donor site morbidity is minimal and its dissection is rather easy. The LSRF may be the first choice in certain reconstructive circumstances.
