Abstract:
Intracranial aneurysm surgery is commonly performed using pinned head holders, which pose a higher risk for the pediatric population. Several authors recommend avoiding the use of this device when it is not strictly necessary, and this is currently possible considering advances in anesthesiology and monitoring. As the literature on microsurgery without skull clamp use is scant, we report the case of a 15-year-old boy presenting with a subarachnoid hemorrhage after rupture of a middle cerebral artery aneurysm. Surgical treatment was performed with the head resting on a gel cushion horseshoe; aneurysm clipping was achieved without wakefulness or awareness and the patient had a good recovery.

Aneurysm I: Introduction
Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
