The temporoparietal flap is based on which artery?

• A. Infraorbital artery
• B. Occipital artery
• C. Superficial temporal artery
• D. Facial artery

Answer: (C)

The temporoparietal flap is primarily based on the superficial temporal artery. This flap is commonly used in reconstructive surgery, particularly for facial defects or to cover injuries in the scalp area. The superficial temporal artery, a branch of the external carotid artery, provides the vascular supply necessary for the viability of the flap. Its course allows for a robust blood supply when the flap is elevated, which is essential for healing and maintaining the integrity of the tissue after transfer. Understanding the anatomical basis of flaps is critical in surgical practice, as choosing the correct flap and ensuring adequate blood supply can significantly impact the success of the procedure. The superficial temporal artery's position and branching patterns make it an ideal source for this particular flap, allowing for both aesthetic and functional restoration.
