Fracture of the cranial bones following trauma is common. The fracture most commonly encountered in clinical practice is an undisplaced linear fracture of a skull bone or a depressed skull fracture. Compound elevated skull fracture, unlike depressed skull fracture is an extremely rare variety of post-traumatic cranial injury, seldom seen in modern clinical practice. Authors report one such rare...
AIM The paramedian forehead flap (PMFF) has been well described for nasal reconstruction. However, it has never been reported for use in the repair of high flow anterior skull base cerebral spinal fluid (CSF) leaks. MATERIAL AND METHODS The patient is a 55 yo African American male cocaine abuser who initially presented with a high flow anterior skull base CSF leak, extensive pneumocephalus, a...
BACKGROUND The impact of transnasal endoscopic approaches to the central skull is still increasing. Its use in small children (i.e., under the age of 5 years) is of questionable value. PATIENTS AND METHODS The present study is a description of a series of five children under the age of 5 years with lesions of the central skull base. RESULTS Three out of five required a combined external and...
complication of skull fracture, occurring almost exclusively in infants and children under the age of three (1, 2). It follows head trauma with accompanying skull fracture. Dural tear associated with skull fracture is the basic mechanism by which this condition occurs. Growing skull fracture is most commonly observed in the frontal and parietal regions, but it can occur anywhere in the skull (3...
the clivus is the surface of a portion of the occipital and sphenoid bones in the base of the skull. (1)it is surrounded by the neurovascular structures of the brainstem, as well as internal carotid arteries. tumors of the clivus can be benign (chordoma)or malignant (chondrosarcoma).(2) chordomas are rare, aggressive, slow-growing, invasive, and locally destructive tumors that arise from the no...
ollier’s syndrome, a variant of multiple enchondromatosis, is a rare disease with an estimated prevalence of 1/100,000, characterized by multiple enchondromas, asymmetrically involving small bones of the hands and feet, especially the proximal phalanges. intracranial enchondromas, such as those arising from the skull base are extremely rare. herein, we report a 25-year-old female, known case of...
The extended anterior subcranial approach, for craniofacial resection of carcinoma involving anterior midline skull base, involves an osteotomy of the fronto-naso-orbital external skeletal frame, so as to provide optimum anterior access to the orbital and sphenoethmoid planes, the nasal and paranasal cavities. A clear advantage is the avoidance of frontal lobe retraction, leading to early posto...
