Neurocranial morphology as determined by asymmetries of the skull base.

The goal of the current study was to provide an easy to use criterion to diagnose neurocranial asymmetries. An anatomical survey of the external aspect of the skull base was planned to correlate with radiological studies. In a sample of 239 skulls, variations of the angular relationship between the structures seen on a basilar view of the cranium were analysed. An anterior and a posterior transverse line were plotted with respect to the midline. Departures from 90 degrees to the midline for either of the transverse lines were less than 5 degrees in normal skulls, between 5 degrees and 7 degrees in skulls classed by independent inspection as asymmetric, and more than 7 degrees in obviously malformed skulls.

Moderate head injuries in children as compared to other age groups, including the cases who had talked and deteriorated.

Patients defined as having a moderate head injury on the basis of Glasgow Coma Scale scores within the ranges of 9 to 13 after acute nonsurgical procedures were selected. Almost 1600 cases were hospitalized in the Neurosurgery Department. The cases were admitted through the Emergency Unit of Gaz University Medical School, Ankara, Turkey during the period between 1979 and 1992. The group studied consisted of 231 selected patients assessed separately in paediatric, adult and elderly age groups. Possible risk factors such as: GCS score, anisocoria, unilateral or bilateral fixed pupils, impaired oculocephalic reflexes, presence of multiple systemic injuries, aetiology of head trauma, presence of linear or depressed skull fractures, space occupying mass on CT or operation was also assessed. Subarachnoid haemorrhage turned out to be the only independent significant risk factor in predicting mortality. The data about the patients who have "talked and deteriorated" were also reported so as to assisst physicians charged with the care of trauma victims.

Sella turcica fractures in a trauma series and their clinical significance.

BACKGROUND: Fractures in the region of the sella turcica (ST) are usually associated with severe blunt head trauma and may produce many complications. The true incidence is difficult to assess since there have been only about 30 cases reported in the literature. METHODS: A total of 470 computed tomography (CT) sections--with optimum bone window images of skull bone--of 1600 head trauma patients who were admitted between 1979 and 1992, inclusive, to the Neurosurgery Department of Gazi University Medical School were analyzed retrospectively. RESULTS: There were a total of 17 patients with a fracture of the ST, constituting an incidence of 3.6%, and there was a preponderance of children. CONCLUSIONS: Computed tomography was very helpful in assessing the extent of ST fractures. In our cases, these fractures were not associated with a high complication or death rate, although a cerebrospinal fluid fistula was present in 53%.

Head trauma and leucocytosis.

A prospective analysis of 153 cases of head trauma was conducted with respect to their white blood cell counts. A white blood cell count exceeding 20 x 10(6)/l is associated with a poor clinical grade on admission and with a 96% mortality as opposed to that of a 23% mortality for those with slightly lower or slightly above normal white blood cell count. The sensitivity for this level is a mortality of 96% while the specificity is 77%.

Co-incidence of Guillain-Barré syndrome and spinal cord compression in non-Hodgkin lymphoma.

Extradural, radicular and spinal cord compressions are severe neurological complications of lymphomas. Less frequently, involvement of the peripheral nervous system, polymyositis, myasthenia gravis and Guillain-Barré syndrome (GBS) occur. We report a patient with GBS along with a lymphoma of the spinal extradural space where at the beginning the features of GBS outweighed the symptomatology of the extradural spinal mass.

Autogenous bone grafts in cervical vertebrectomy and fusion practice for injuries.

Among the patients with a cervical injury admitted to our clinic between 1980 and 1988, 18 cases underwent a ventral fusion operation (Cloward) and 8 of them needed additional vertebrectomy. The injury in all of these cases was due to falls and presented with major compression fractures. In each case the vertebral body was resected and replaced by a "T" shaped iliac bone graft. The graft was fixated by a screw or wire when necessary, than the patients were immobilized by a bed rest for 2 weeks duration. During the follow-up period, cervical alignment was found to be stable in all patients. The radiological characteristics of the lesions, intraoperative surgical modifications for specific aspects of the lesion, other technical availabilities and the results are discussed.

Observation of 95 patients with extradural hematoma and review of the literature.

The authors review the cases of 95 patients with extradural hematoma managed at Gazi Hospital in the last 4 years. The common factors in craniocerebral traumas, the time interval between admittance and trauma, the interval between admittance and operation, and the location of hematomas are determined. The arterial origins demonstrated at operation in extradural hematomas are described. The interactions between all these factors and mortality are discussed. Availability of computed tomography scanning accounts for the present mortality rate of 9.4% when compared with the mortality rate of 33% for conventional diagnostic facilities.
