Crossbow cut

R. of the skin during trephination of the posterior cranial fossa, the arcuate part of which connects the mastoid processes, passing 1.5-2 cm above the external occipital protrusion, and the vertical part runs along the midline from the top of the arcuate part to the spinous process of the V or VI cervical vertebra.

The crossbow incision is an incision used in surgery for craniotomy. It is named after the crossbow that was used in medieval Europe for archery.

To carry out the Crossbow incision, it is necessary to make an arcuate part that connects the mastoid process, passing 1.5-2 centimeters above the external occipital protrusion. The vertical part of the incision runs along the midline, from the apex of the arcuate part, to the spinous process of the fifth or sixth cervical vertebra.

The Crossbow incision is used to trephine the posterior part of the cranial fossa. This incision allows access to the meninges, spinal cord, and spine, and to remove tumors, cysts, and other abnormal growths.

One of the advantages of the Crossbow incision is that it provides wide access to the operated area, which makes it more convenient for surgical procedures. In addition, this incision has low trauma, which reduces the risk of complications after surgery.
