Simple lip reconstruction technique for middle-sized defects in lower lip cancer - Bilateral oblique mucosal V-Y advancement flap

There is no standardized technique for lip reconstruction because the structure and functions of the lip are diverse. We developed a new lip reconstructive approach using a bilateral oblique mucosal V-Y advancement flap.We present the case of a 76-year-old woman with severe dementia, referred to our institute for a tumor on her lower lip. She was diagnosed with lip squamous cell carcinoma (cT2N0M0). The tumor measured 25 x 20 mm. It was resected with a surgical safety margin of 6 mm. Bilateral triangular flaps were fashioned obliquely on the rear lateral side of the defect extending from the labial to the buccal mucosa and used to repair the defect. The operation time was 66 min. She was discharged on the fourth postoperative day without any complications. Speech and food intake functions have been preserved and she has been followed up for 26 months with no recurrence. The lip closing and color match has been adequate despite a slight thinning of the lip.This technique offered a major benefit of short operation and hospitalization time because it was a simple, less-invasive, one-step procedure. This is a practical procedure, suitable for vulnerable patients of advanced age or with comorbidities.(c) 2023 Japanese Society of Otorhinolaryngology-Head and Neck Surgery, Inc.
