Abstract:
Extensive squamous cell carcinoma involving the skin of the upper lip, nasal ala, and cheek is relatively rare. Although numerous reconstruction techniques for the midface including lip, nose, and cheek have been described in the literature, reconstruction of large defects in this area continues to be challenging, as it is difficult to obtain satisfactory results with single-stage surgery. This case report concerns a 53-year-old woman with squamous cell carcinoma extending from the upper lip to the alar base and the cheek. It describes a step-by-step surgery undertaken according to defined regional aesthetic units of the face using several reconstruction methods, including a microvascular free flap, forehead flap, and conchal cartilage graft, rather than multistage reconstruction surgeries after first immediate reconstruction. Satisfactory functional and aesthetic results were achieved despite the extensive facial defects.
