BACKGROUND AND PURPOSE There is a wide range of normal variation is sphenoid sinus development, especially in the size of the lateral recesses. The purpose of this study was to determine imaging characteristics that may help differentiate between opacification of a developmentally asymmetric lateral recess and a true expansile lesion of the sphenoid sinus. METHODS Coronal CT was performed in ...

BACKGROUND Sphenoid sinus is the most inaccessible paranasal sinus, enclosed within the sphenoid bone and intimately related to numerous vital neural and vascular structures. Anatomic variation of the sphenoid sinus is well documented and may complicate surgery in such a place. OBJECTIVE To outline the surgically risky anatomic variants of the sphenoid sinus as well as the variable relationsh...

Abstract Introduction The use of endoscopic sinus surgery in the field otorhinolaryngology is due to many reasons such as better visualization, complex anatomy skull base and relations between vital vascular nervous elements, crucial preoperative knowledge about detailed area, computed tomography that a useful tool for them plan safest route surgery. foramen rotundum (FR) inherent bony structur...

Cerebral arteriography performed in two children for cerebral pathology incidentally revealed prominent arterial supply to pharyngeal tonsillar tissue arising directly from the internal carotid arteries bilaterally. Embryologic considerations seem to indicate developmental origins of this vessel from early emanations of the first fetal aortic arch. Clinical implications revolve around the possi...
