Clinical outcomes of bilobed platysma myocutaneous flap technique with neck dissection in lower lip squamous cell carcinoma.

BACKGROUND: Squamous cell carcinoma (SCC) in the lower lip is among the most frequently encountered types of cancer. As the size of this cancer increases, the need for reconstruction becomes evident, posing a significant challenge. Depending on the staging results in these patients, neck dissection may be recommended. OBJECTIVE: This study aims to demonstrate the successful application or feasibility of our Bilobed Platysma Myocutaneous Flap technique in patients with lower lip SCC. METHODS: The Bilobed Platysma Myocutaneous Flap was applied to all patients. Following TNM staging, supraomohyoid and/or radical neck dissection were performed. Surveys were conducted with the patients, and scoring was implemented based on the results for evaluation. RESULTS: Between 2014 and 2018, 23 patients underwent treatment with this flap, and all flaps survived. Among these patients, bilateral supraomohyoid neck dissection was performed on 14, while modified radical neck dissection on one side and supraomohyoid neck dissection on the other side were conducted on the remaining 9 patients. Throughout the 5-year follow-up period, no recurrence was observed in the patients. CONCLUSION: The combination of the Bilobed Platysma Myocutaneous Flap technique and neck dissection can be successfully employed in the reconstruction and treatment of lower lip cancers.
