Reconstruction of Head and Neck Defects with Lower Trapezius Myocutaneus Flap

Abstract

Introduction High lateral and posteriorly based defects are challenging to reconstruct as mobilization of conventional pedicled flaps is difficult. This study was done to evaluate the usefulness of lower trapezius myocutaneous flap (LTMC) in selected cases as a reconstructive alternative to other pedicled flaps which have positional and technical disadvantages and/or in cases where free flap is not possible. Materials and Methods Ten cases of locally advanced (T3 and T4) high and laterally placed head and neck carcinoma (8 cases of SCC involving posterior scalp, ear lobule, skin anterior to tragus and 2 cases of locally advanced salivary gland malignancies involving parotid glands) irrespective of sex had been selected. Due to non-availability of plastic surgeon in the institute none of the patient could be subjected to free flap reconstruction. All the patients received post operative adjuvant radiotherapy and were followed up on a monthly basis for six months at least. Results Out of total 10 cases 5 underwent wound infection and dehiscence at recipient site. In 3 cases there were donor site seroma. In 2 cases healing was uneventful. However in all cases the flap was healthy and flap survival was 100%. There was no flap contracture in long term follow up. Conclusion The LTMC flap is ideal for mentioned defects because of its anatomical location, abundant blood flow, minor donor-site morbidity, and long pedicle. The LTMC flap, though less commonly used, is a precious option in situations where free flaps and other pedicled flaps are not feasible.
