What is required to adhere the scalp to the bone flap during a craniotomy?

During a craniotomy, Raney clips are specifically designed to secure the scalp to the bone flap. They are small clips that have a unique design which allows them to hold tissue firmly, providing effective stabilization during the procedure. The use of Raney clips helps to maintain the position of the scalp while ensuring good visibility for the surgical team.

In contrast, stitches and sutures are typically used for closing the skin after the procedure rather than for securing the scalp during the operation. Adhesive spray may be used in some contexts, but it does not provide the mechanical support needed in this situation. Therefore, Raney clips are the optimal choice for adhering the scalp to the bone flap in a craniotomy due to their effective locking mechanism and ease of use in maintaining tissue position during surgery.
