This article presents the case of an 81-year-old male referred to the maxillofacial department for extensive lower lip squamous cell carcinoma (SCC). While SCC of the lip is among the most easily detectable and treatable malignancies, surgical treatment can sometimes lead to significant defects, impacting both lip function and facial aesthetics. The patient underwent a comprehensive W-type excision and primary closure, complemented by a right suprahyoid neck dissection. This case report emphasizes the successful reconstruction of a large defect using primary closure, achieving both functional and aesthetic preservation. During follow-up, the patient demonstrated optimal healing, with intact function, satisfactory cosmetic outcomes, and no clinical or imaging evidence of recurrence or distant metastasis.
