Abstract
Background: Reconstruction of lip defects following oncologic resection is a demanding task, as both functional and aesthetic outcomes must be preserved. When the oral commissure is involved, regional flaps such as the Abbe–Estlander remain important tools in achieving reliable reconstruction. Case Presentation: A 35-year-old male laborer with a history of smoking presented with a progressively enlarging lower lip lesion of seven months’ duration. Biopsy confirmed well-differentiated squamous cell carcinoma extending to the oral . The patient underwent wide local excision with a 1-cm margin and supra-omohyoid neck dissection, followed by commissural reconstruction using an Abbe–Estlander flap. The immediate post-operative course was uneventful. At two weeks, mild microstomia was noted, though oral continence and speech were preserved. Final histopathology confirmed well-differentiated squamous cell carcinoma with tumor-free margins. On follow-up at 3, 6, and 12 months, the patient maintained satisfactory function and cosmesis. Conclusion: The Abbe–Estlander flap remains a dependable reconstructive method for lip carcinoma involving the commissure. It offers oncological safety while restoring oral competence, articulation, and symmetry with minimal morbidity. Despite advances in microsurgical techniques, this flap continues to be an effective andpractical option, particularly for medium-sized commissural defects.
