In temporalis flap procedures for disk replacement, which muscle is used?

• A. Masseter muscle
• B. Buccinator muscle
• C. Temporalis muscle
• D. Sternocleidomastoid muscle

Answer: (C)

In temporalis flap procedures for disk replacement, the temporalis muscle is utilized because it is specifically designed to provide the necessary soft tissue and vascular supply for the flap. The temporalis muscle is located on the side of the head and is responsible for elevating the mandible and aiding in mastication. During the surgical procedure, a portion of this muscle is elevated and repositioned to replace or support the temporomandibular joint disk. The unique anatomical features of the temporalis muscle, including its robust blood supply and suitability for adapting to the temporomandibular joint area, make it an ideal choice for such reconstructive flaps. It allows for effective healing and restoration of function in the joint area. Other muscles, such as the masseter, buccinator, and sternocleidomastoid, do not have the anatomical properties or the correct position that would facilitate their use as a flap for this specific purpose in the temporomandibular joint area, thereby making the temporalis muscle the correct and preferred choice.
