Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit.Exophthalmos can be either bilateral (as is often seen in Graves' disease) or unilateral (as is often seen in an orbital tumor).Complete or partial dislocation from the orbit is also possible from trauma or swelling of surrounding tissue resulting from trauma. The "carotid space" terminology was introduced by some radiologists to facilitate differential diagnosis and is used in this article 1.However, in much of the surgical and anatomical literature, the carotid space within the suprahyoid neck is considered part of the parapharyngeal space 2,3.Under this nomenclature, the parapharyngeal space is divided into In 1773, John Fothergill was the first to fully describe trigeminal neuralgia in an article presented to the Medical Society of London titled On a Painful Affliction of the Face.In 1829, Charles Bell distinguished the specific functions of the trigeminal and facial nerves and introduced the idea that the paroxysmal pain in trigeminal neuralgia is directly related to nerve dysfunction. Endoscopic third ventriculostomy (ETV) is a minimally invasive procedure indicated for the treatment of hydrocephalus. It is a network of veins that sit in a cavity.It sits on both sides of the sphenoidal bone and pituitary gland, approximately 1 2 cm in size in an adult. 1.1. Terminology. It articulates with the adjacent temporal, parietal, frontal, occipital, ethmoid, zygomatic, palatine, and vomer bones and its intricate microanatomy includes numerous foramina. The additional bone removal at the sphenoid wing and orbital roof expands the subfrontal operative trajectories toward the midline skull base while reducing retraction on the frontal lobe.
