The purpose of this study was to investigate the sphenoidal sinus septation in a select South African population, and document the relation of the number and location of the septa to the structures intimately related to the sinus. The intersinus and intrasinus septa of the sinus, the number and attachmen...
Objetivo: Aportar valores teóricos promedio de referencias anatómicas en tomografía computada con el fin de optimizar los abordajes transesfenoidales a la base de cráneo.
Materiales y Métodos: Se desarrolló un diseño descriptivo, prospectivo, transversal y observacional de cien estudios de tomogra...
Introdução: fístula liquórica rinogênica é uma comunicação do espaço subaracnóideo com a fossa nasal ou seios paranasais, decorrentes a um defeito anatômico da dura-máter, osso e mucosa. As fístulas liquóricas nasais espontâneas são eventos raros, cerca de 3%, com possíveis complicaçõe...
SUMMARY: The morphology of the sphenoid air sinuses is variable amongst populations. The variation in terms of the morphology of this air sinus is particularly important in cranial base surgery. This study aimed to illustrate the three dimensional (3D) morphology of the sphenoid air sinus across ages 1 t...
Abstract Introduction: The medial maxillary sinus roof is a ridge formed by the superior margin of the maxillary sinus antrostomy. The posterior wall of the maxillary sinus is always included in operative fields. Objective: To perform a radiologic study assessing the utility of the medial maxillary sin...
Abstract Introduction: The sphenoid sinus is an important structure in ventral skull base surgeries that is surrounded by several vital anatomical structures including the internal carotid arteries, optic nerve and cranial nerves inside the cavernous sinus. In addition, the foramen rotundum is a small c...
Abstract Introduction: When an expanded endonasal transsphenoidal surgical approach is performed, intrasphenoid septations must be completely resected. If these structures are close to the internal carotid artery (ICA), then their manipulation might cause vascular injury. Objective: The objective of th...
ABSTRACT Objective To evaluate the intercarotid distance (ICD) of patients with pituitary macroadenoma and compare to heatlhy controls. Method We retrospectively reviewed contrast-enhanced MRI images from twenty consecutive patients diagnosed with non-functioning pituitary macroadenoma, measured the ...

There are a number of variations regarding morphometric anatomy and degree of pneumatization of the sphenoid sinus. In our study, we planned to examine and show the differences of pneumatization of the sphenoid sinus particularly to guide the neurosurgeon during transsphenoidal surgery. Sagittal T1-weigh...
