There is a need to better understand the threshold for paediatric skull fracture. Historically, drop tests of cadaver heads have been used to estimate thresholds. However, societal and ethical considerations prevent tests with child cadavers. Therefore, researchers have attempted to estimate the threshold by scaling adult tolerance data. Recent work suggests that mass and material scaling of ad...
BACKGROUND Sphenoid sinus fungal balls (SSFB) are rare entities that can result in serious orbital and intracranial complications. There are few published reports of complications that result from SSFB. OBJECTIVE To review the incidence of skull base erosion and orbital or intracranial complications in patients who present with SSFB. METHODS A retrospective review was performed of all the p...
introduction: epidermoid tumors comprise 1% of intracranial tumors. although reported, intraosseous epidermoid tumors are even more rare. cystic lesions of the petrous apex are uncommon and surgically challenging; the most rare pathology is presumed to be epidermoid.rncase presentation: this is a case of a 61-year-old woman with a large skull-base tumor extending inferiorly from the c1-c2 artic...
The aim of this report is to present two cases of canalis basilaris medianus as identified on cone-beam computed tomography (CBCT) in the base of the skull. The CBCT data sets were sent for radiographic consultation. In both cases, multi-planar views revealed an osseous defect in the base of the skull in the clivus region, the sagittal view showed a unilateral, well-defined, non-corticated, tra...
This work develops a generalized linear skull fracture criterion, the skull fracture correlate, SFC, applicable to impacts by flat targets on the skull in any angle. The SFC is the averaged acceleration over the HIC15 time interval based on data obtained from Hybrid-III headform impact tests. For 15% or less probability of skull fracture the threshold is SFC < 124 g, with a 95% confidence band ...
