OBJECTIVE Reconstruction of the cranial base using vascularized tissue promotes rapid and complete healing, thus avoiding complications caused by persistent communication between the cranial cavity and the sinonasal tract. The Hadad-Bassagasteguy flap (HBF), a neurovascular pedicled flap of the nasal septum mucoperiosteum and mucoperichondrium based on the nasoseptal artery, seems to be advanta...

The responses of cerebral (pial) arterioles to increased venous pressure were examined in anesthetized cats equipped with cranial windows for the observation of the cerebral microcirculation. Increased venous pressure was induced by occlusion of the superior vena cava. Intracranial pressure was kept constant. Increased venous pressure when the window was filled with stationary cerebrospinal flu...

INTRA-ocuLAR pressure varies from individual to individual, from right eye to left eye, and from time to time. Many manometric studies have been made on experimental animals but observations on human eyes have been few: Wessely (1915, 1916) found an average of 22 5 and 18X5 mm. Hg, and Seidel (1922) one of 20 and 25 5 mm. Hg. Tonometric studies of human eyes, however, have been many; the result...

Background and Importance: Arachnoid cysts are benign nontumoral lesions that are usually found incidentally in brain imaging. Suprasellar Arachnoid Cysts (SSACs) are rare. They can cause hydrocephalus and increased intracranial pressure, lower cranial nerve impairment and endocrine disorder. Sometimes arachnoid cysts become complicated by subdural hematoma/hygroma.  Case Presentation: We...
