Endonasal endoscopic approach to the skull base has been expanded in the last several years owing to advances in the radiological aspect that provided a better evaluation of the lesions an...
Skull pin insertion during craniotomies is a brief, intensely stimulating, painful stimuli occurring during the conduct of a neurosurgical or spine anesthetic. Remifentanil is an ultra sho...
Skull pins are used to immobilize the head during craniotomy. Fixation of skull pins causes acute hemodynamic changes which may affect cerebral autoregulation and hence cerebral blood flow...
Since Chiari malformation is a common disease, many patients require surgical operation to relieve pressure from the back portion of the skull. The purpose of this research is to compare t...
The goal of this clinical research study is to learn if proton beam therapy, with or without photon beam radiation therapy, is effective in the treatment of skull base chondrosarcoma. The ...
To see effectiveness of the senior author's repair technique for repair of large (equal to or larger than 10 mm) bony lateral skull base defects.
Bilateral choanal atresia (BCA) is associated with a high incidence of congenital abnormalities that include skull base anomalies and defects. Surgical repair of BCA is necessary in the early neonatal...
Idiopathic intracranial hypertension is a disease of elevated intracranial pressure that can lead to spontaneous cerebrospinal fluid leak at the skull base. We present a case of CSF leak in a young fe...
Results of hybrid arch repair (HAR) utilizing native zone 0 proximal landing zone (PLZ) have been unsatisfactory in many series, especially in the setting of ascending aortic dilation (>4.0 cm). This ...
Temporal bone tegmen defects may be associated with cerebrospinal fluid (CSF) otorrhea. A variety of techniques have been used for repair. We report our experience with skull base reconstruction for t...
Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS). Skull fractures may be classified by location (e.g., SKULL FRACTURE, BASILAR), radiographic appearance (e.g., linear), or based upon cranial integrity (e.g., SKULL FRACTURE, DEPRESSED).
Traumatic injuries to the cranium where the integrity of the skull is not compromised and no bone fragments or other objects penetrate the skull and dura mater. This frequently results in mechanical injury being transmitted to intracranial structures which may produce traumatic brain injuries, hemorrhage, or cranial nerve injury. (From Rowland, Merritt's Textbook of Neurology, 9th ed, p417)
Neoplasms of the base of the skull specifically, differentiated from neoplasms of unspecified sites or bones of the skull (SKULL NEOPLASMS).
A skull fracture characterized by inward depression of a fragment or section of cranial bone, often compressing the underlying dura mater and brain. Depressed cranial fractures which feature open skin wounds that communicate with skull fragments are referred to as compound depressed skull fractures.
The reconstruction of a continuous two-stranded DNA molecule without mismatch from a molecule which contained damaged regions. The major repair mechanisms are excision repair, in which defective regions in one strand are excised and resynthesized using the complementary base pairing information in the intact strand; photoreactivation repair, in which the lethal and mutagenic effects of ultraviolet light are eliminated; and post-replication repair, in which the primary lesions are not repaired, but the gaps in one daughter duplex are filled in by incorporation of portions of the other (undamaged) daughter duplex. Excision repair and post-replication repair are sometimes referred to as "dark repair" because they do not require light.
