Bilobed Flap: A Surgical Alternative in Nasal Ulcerated Basal Cell Carcinoma

Abstract

Basal cell carcinoma was first described by Jacob in 1827 as a very slow-growing ulcer on the face, with peculiar edges reminiscent of a rat bite, which is why it was called “Ulcus Rodens” and over time it has received various denominations. Basal cell carcinomas: are defined as malignant epithelial tumors located in the skin, arising from pluripotent cells in the basal area of the epidermis and the external root sheath of the hair at the level of the lower isthmus and pons. They are slow growing, rarely produce metastases, have local destructive capacity, and compromise extensive areas of tissue, cartilage and even bone. They develop in photo-exposed areas of individuals with a light phototype, between the third and sixth decade of life. Treatment for patients with basal cell carcinoma includes: surgical and non-surgical options, among surgical options, excision is the standard therapy, considered effective since it has cure rates of 9 to 95% at 5 years; which is why it was the treatment chosen for our case with subsequent reconstruction of the surgical defect. For surgical reconstruction, several types of flaps can be proposed, including the bilobed flap, which is a double transposition flap that shares a single base.
