Traumatic injuries of the abducens nerve as a consequence of facial and/or head trauma occur with or without associated cervical or skull base fracture. This is the first report on unilateral avulsion of the abducens nerve in a 29-year-old man with severe right facial trauma. In addition, he exhibited mild left facial palsy, and moderate left hearing disturbance. Magnetic resonance imaging (MRI...

It can be challenging to create a safe airway in maxilla facial fracture and some skull surgeries. In this case study, the patient experienced jaw fractures that disturbed the dental occlusion and associated fracture of the base of the skull. Neither nasal nor oral intubation was possible based on the side effects of tracheotomy; therefore, submental intubation was applied successfully. The pro...

BACKGROUND Clivus is a bony surface in the posterior cranial fossa, serving as the support of the brainstem and thus neighboring important structures because of its location. Skull base fractures that cannot be shown by conventional radiography can be clearly imaged by high-resolution bone window computed tomography. CASE REPORT A 44 years-old male referred to the emergency department because...

introduction: skull-based osteomyelitis is bony infection which generally originates from inadequately treated chronic infection, adjoining tissue infection or after trauma.case: 11 month female child had a trivial fall while standing near a bucket. the child developed fracture of right clavicle and left orbital swelling which was inadequately treated. this resulted in in spread of infection to...

Complications of basilar skull fracture, such as carotid cavernous fistulae, meningitis, cerebrospinal fluid rhinorrhoea and otorrhoea, pneumatocele, and various cranial nerve disturbances, are well known (Gurdjian and Webster, 1958). In -addition, unilateral thrombosis of the internal carotid artery, both with and without basilar skull fracture, has frequently been reported after closed head a...

localization of brain lesions and prevention of damage to vital structures are important in operation of brain pathologies. despite development of many techniques including angiography, mri, sonography, and frame base stereotaxy, a more accurate localizing technique is still needed (1, 2). a step forward to achieve this goal is to develop a navigation system. in this manuscript, we explained so...

introduction: skull base meningiomas constitute a large proportion of the meningiomas, which are the most common benign brain tumors. the treatment of skull base meningiomas is specially challenging and controversial due to the proximity of these tumors to the vital brain structures. radiosurgery is now emerging as an efficient alternative treatment modality which involves the ablation of tumor...
