PURPOSE: Lateral trapezius myocutaneous (LTMC) flap has been used less frequently for defects pertaining to head and neck cancer ablative surgical defects. This study is to assess the utility of LTMC flap with a new modification of the flap design. METHODS: This is a retrospective study using LTMC flap with modifications as a reconstructive option for intraoral & extraoral skin defects in head and neck cancer patients following ablative surgery, from August 2014 to October 2019 in a tertiary care hospital. The original technique of LTMC flap was modified for better results and outcomes. RESULTS: Thirty-five patients underwent lateral trapezius flap reconstruction for ablative defects of oral cavity, laryngopharynx, neck and parotid. Twenty-three patients (65.71%) underwent adjuvant radiation/radiation-chemotherapy while one patient defaulted. Two patients (5.71%) had major flap failure. After the loss of flap in these patients, the operative technique was further modified for better results. However, the disadvantage of using this flap is shoulder disability. Nonetheless in the present study, the disability was reduced after modifying the operating technique by preserving the spinal accessory nerve. CONCLUSION: The present study demonstrated minimal functional loss, low morbidity with satisfactory results, thus also reducing treatment cost. Thus, LTMC is a reliable reconstructive option in head and neck cancer patients for medium-sized defects.
