BACKGROUND: The available referential measures defining the zygomatic bone morphology are adequate enough for full determination of the zygoma positioning, especially for trauma surgery, but osteometric analysis of the zygoma positioning based on tomographic examinations could be useful in peroperative and postoperative imaging. In this study, we propose referential measures, taking into account the morphology and the symmetry of the zygoma. In addition, the reliability and reproducibility are considered...

We report a rare case of entrapment of the basilar artery into the sphenoid bone caused by a longitudinal fracture of the clivus. Using high resolution three-dimensional flat panel angiography, we show preservation of the basilar artery perforators in spite of severe stenosis of the entrapped segment of the basilar artery. There were no obvious signs and symptoms of posterior fossa stroke clinically or radiographically as far as could be assessed under given clinical circumstances.

OBJECTIVE: To analyze the impact of maxillofacial injury on skull base. METHODS: A three-dimensional(3D)finite-element model of cranio-maxillofacial bone was established by CT scan data. A lead cylinder in base diameter of 3 cm was designed as an impactor. There regions(upper right maxilla, left infraorbital margin and left zygomatic body)subjected to an impact at the speed of 8.6 m/s(about 30 km/h)was simulated. Thirteen landmarks at the skull base were selected...

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, track-like low-attenuation osseous defect in the clivus. The appearance of the defect was highly reminiscent of a fracture of the clivus...

BACKGROUND: Vertebrobasilar artery entrapment due to a clivus fracture is very rare. The entrapped lesions were not radiographically depicted precisely as they were only identified by autopsy or completely occluded. Also, no changes in the features have been revealed clearly because radiological examinations were performed only in the acute stage. CASE DESCRIPTION: We report a case of traumatic entrapment of the vertebral artery depicted precisely by a 3 dimensional angiographic study in the subacute stage, presenting the serial changes in the morphological features and also a review of the published cases...

OBJECTIVES: Routine transnasal rhinological procedures are widely practiced and are considered as safe, in general. Skull base lesions occur in less than 1% of procedures and typically involve the anterior or middle cranial fossa, while clivus lesions have not been well documented. Here we present a series of three patients with iatrogenic transclival lesions after routine transnasal rhinological procedures. PATIENTS AND METHODS: Three patients with penetrating clivus injuries after routine transnasal rhinological procedures were identified...

Unlike basilar skull fractures, penetrating traumatic injuries to the clivus are uncommon. We present two novel and interesting cases of traumatic crossbow arrow injury and penetrating screwdriver injury to the clivus. A review of the literature describing methods to repair these injuries was performed. A careful, systematic approach is required when working up and treating these injuries, as airway preservation is critical. An adaptation to the previously described "gasket-seal" method for skull base repair was utilized to repair the traumatic cerebrospinal fluid (CSF) fistulas...

An 89-year-old male presented with cerebrospinal fluid (CSF) rhinorrhea associated with head trauma sustained as a pedestrian in a traffic accident. Computed tomography (CT) showed pneumocephalus and multiple cranial bone fractures, including the clivus. Although the CSF rhinorrhea was treated conservatively for a week, clinical symptoms did not improve and surgical repair was performed. Preoperative thin-sliced bone CT and steady-state magnetic resonance images revealed a bone defect at the middle clivus and a collection of CSF fluid from the clival fistula in the sphenoid sinus...

INTRODUCTION: Clivus is a central structure of the skull base located in the vicinity of the brainstem and vital brain vessels. Clival fractures are usually caused by a high-energy trauma. Cerebrospinal fluid leak is one of the most common complications. CASE REPORT: A middle-aged male sustained a mild head trauma, followed by a nasal cerebrospinal fluid leak. CT scan revealed the massive pneumocephalus and the fracture of the clivus in the posterior wall of the sphenoidal sinus...

BACKGROUND: Cranieovertebral junction lesions in the paediatric population are associated with a low survival rate, which has declined in recent years. Neurological disability is a major concern due to the high economical cost it represents. Paediatric patients are more susceptible to this lesion because of hyperextension capacity, flat articulation, and increased ligamentous laxity. Survival after these kinds of injuries has been more often reported in adults, but are limited in the paediatric population...

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 of a traffic accident in the car. His only complaint was a severe neckache...

Longitudinal clivus fractures are rare in children, with only 5 cases published in the English literature to date. Clivus fractures, particularly longitudinal type, are associated with high mortality and morbidity. We report a case of longitudinal clivus fracture in a teenager with survival and complete neurological recovery. Our case is the first pediatric case of longitudinal clivus fracture caused by frontal impact and the first described pediatric case associated with transient diabetes insipidus (DI).

The entity of pituitary (sellar or parasellar) lymphoma includes primary pituitary lymphoma (PPL) and secondary pituitary lymphoma (SPL). The latter has an involvement of systemic lymphoma. Both of these lymphomas are extremely rare. We describe a patient with SPL showing a good prognosis. A 78-year-old woman presented with diplopia, left ptosis, and back pain. Magnetic resonance (MR) imaging revealed a parasellar mass lesion extending to the upper clivus and another mass lesion with compression fracture of the Th3 vertebral body...

BACKGROUND: The transoral approach allows for an unobstructed anterior view of the craniovertebral junction from the lower clivus to C1 and C2. It can be applied to a heterogeneous spectrum of pathological lesions involving this area including craniovertebral junction malformations, atlanto-axial synovial cysts, pseudoarthrosis following odontoid fractures, selected cases of retro-odontoid pannus, and vertical translocation in rheumatoid patients. METHODS: Microsurgical strategy is dictated by the nature and site of the target lesion...

Clivus fracture (CF), which is usually reported to accompany with head trauma, has high mortality rates. Early diagnosis of CF is rare because of high mortality rates and inadequate urgent radiologic techniques; however, diagnosis rates are increasing with computed tomography images obtained in high resolution and thin sections. In this article, radiologic and clinical features of 2 patients who were detected to have longitudinal CF after head trauma are presented and accompanying pathologies and its importance for prognosis are discussed under the light of literature data composed of a small number of reports...
