Abstract

Foramen magnum comprises a channel of bones which are formed by clivus, atlas, jugular tubercle, occipital condyle, odontoid process, occipital bone and intervertebral spaces. The forth ventricle, inferior vermis, cervicomedullary junction and the cerebellar tonsils are located at the foramen magnum. The C1 and C2 roots, cranial nerves IX, X, XI, spinal and vertebral arteries are enclosed by the foramen magnum. Jugular bulb, venous sinuses and veins surround the foramen magnum. It is important for the surgeon to have knowledge about these anatomical structures and try to avoid retraction or manipulation of these structures while approaching the lesions of this area.
