Abstract

Basal cell carcinoma (BCC) is the most common type of skin cancer, predominantly affecting the facial area. Particularly, BCC lesions in the nasal–periorbital region often result in extensive and deep defects after surgical excision, significantly impairing both function and aesthetics. Therefore, reconstructing these postoperative defects presents substantial challenges and often requires the use of one or multiple complex reconstructive techniques. This study aimed to evaluate the characteristics of nasal–periorbital defects following BCC excision and the outcomes of median forehead flap reconstruction at the National Hospital of Dermatology and Venereology. A retrospective cross-sectional study was conducted on 17 patients from January 2020 to October 2024. The lesions were primarily located on the nasal ala (36.1%) and lower eyelid (75%). Most tumors were excised using Mohs micrographic surgery (64.71%). The resulting defects had a median size of 4.0 [3.0 – 5.5] cm, with 82.35% involving full-thickness tissue loss. The median forehead flap alone was used in 52.94% of cases. The proportion of good outcomes at both immediate postoperative and 6-month follow-up was 76.5%. The main complications were uneven flap thickness (too thick or too thin) and unsatisfactory scarring. The results indicate that the median forehead flap is a safe and effective method for reconstructing nasal–periorbital defects following BCC excision. Factors that may influence the treatment outcome include the size, morphology, and location of the defect following tumor excision.
