How does the donor site morbidity of an anterolateral thigh (ALT) flap compare to that of a radial forearm free flap (RFFF)?

• A. Lower with ALT
• B. Higher with ALT
• C. Equal for both flaps
• D. Varies by patient

Answer: (A)

The donor site morbidity associated with an anterolateral thigh (ALT) flap is considered lower compared to that of a radial forearm free flap (RFFF). This is largely due to the anatomical and functional characteristics of the two locations. The ALT flap is harvested from the anterolateral aspect of the thigh, which typically leaves a relatively inconspicuous scar and preserves the surrounding muscle function. Additionally, the thigh is a large, muscular area that can tolerate defects better than the forearm, which is more functionally significant for daily activities and often more sensitive. After harvesting, patients usually have fewer complaints regarding aesthetic and functional deficits from the thigh donor site, as compared to the RFFF, which involves the forearm and may result in notable functional complications and a more visible scar. In contrast, the radial forearm free flap, while highly versatile for reconstruction, often results in higher functional morbidity such as loss of forearm strength, grip ability, and sometimes nerve damage due to the harvesting of a more delicate and essential area. These factors contribute to a higher incidence of long-term complications such as neuroma formation or decreased range of motion in the wrist and hand after harvesting from the forearm. Overall, the ALT flap offers a favorable balance with
