The mouth is a unique and prominent element of the lower face. Given the complex anatomy, aesthetic appearance, and function of the oral commissure, its reconstruction due to various causes presents a significant challenge for surgeons. Squamous cell carcinoma (SCC) of the lip is the most common type of oral cancer, accounting for approximately 25% to 30% of all oral cancers. Wide excision is the treatment of choice, and the prognosis is generally favorable. We encountered a case of SCC of the right oral commissure in a 69-year-old man. We designed a hatchet-shaped flap to minimize anatomical disruption and, as a result, achieved satisfactory outcomes in terms of both functionality and aesthetics.
