Interpolated Melolabial Flap sebagai Pilihan Rekonstruksi Estetis dan Fungsional untuk Defek Nasal Akibat Karsinoma Sel Basal: Laporan Kasus Serial

Abstract

Basal cell carcinoma (BCC) is a malignant skin neoplasm primarily induced by prolonged ultraviolet (UV) radiation exposure. Various flap techniques, including rotation, transposition and advancement flaps are commonly employed for reconstruction. This report presents two cases of nasal BCC managed using an interpolated melolabial flap as a reconstructive option. The first case involved a 48 years old woman presenting with a progressively enlarging nodule on the left nasal area for one year. The second case was a 58 years old woman with a similar lesion on the right nasal side. Both patients were diagnosed with BCC based on clinical history, dermoscopic evaluation and histopathological confirmation. Wide local excision with adequate surgical margins was performed in both cases, followed by nasal ala reconstruction using an interpolated melolabial flap. Postoperative outcomes were favorable with minimal complications and no evidence of recurrence during follow up. The primary goal of BCC treatment is complete tumor excision with minimal recurrence while also preserving both function and aesthetic integrity. The choice of flap technique is guided by factors such as defect size, anatomical location, tissue characteristics and patient condition. The interpolated flap technique involves transferring tissue while maintaining a skin bridge (pedicle) to ensure sufficient vascular supply and making it a reliable option for complex nasal reconstructions. The interpolated melolabial flap offers excellent aesthetic and functional outcomes with rapid healing and minimal complications, making it a valuable reconstructive approach in the management of nasal basal cell carcinoma.
