CT signs of pressure induced expansion of paranasal sinus structures

چکیده
Several articles have been written about hyper infl ated sinus structures. Never before, however, a complete overview of all possible pressure induced variations of sinus anatomy have been published. The aim of this study was to make an inventory of the most common CT signs of hyper infl ated paranasal sinus structures. During a period of 2 years all CT-scans of the paranasal sinuses made in an ENT-department were studied and the most typical shapes of hyper infl ated sinus structures were recorded.

Age Differences of Human Frontal Sinus Measurements using CT Scan
Background and Objectives: The frontal sinus is regarded as one of the human paranasal sinuses located in the frontal bone as a triangular-shaped cavity, which originates as separated space from the anterior ethmoid cells. Computed Tomography (CT) is a completely non-destructive technique that uses a high density of contrast to identify the air inside any bony sinus with soft tissue demarcated ...

The paranasal sinuses were prospectively evaluated by CT, clinical history, and physical examination in infants and children having cranial CT for indications unrelated to upper respiratory inflammation (URI). One hundred and one CT scans were studied, and sinus abnormalities were detected in 18% of patients older than 1 year and without signs or symptoms of URI. When signs and/or symptoms of r...

ABSTRACT: Brain abscess is a localized parenchymal infection of the brain , which may develop from three sources:(1)by direct extension of preexisting infection in the paranasal and mastoid sinus.(2) from cranial trauma,(3) by hematogenous spread. Brain abscess occurs more frequently in the young and in males. With more common utilization of anaerobic cultures,it has become apparent that a gr...
متن کاملParanasal sinus mucocele.
Mucocele of the paranasal sinuses is a distinct clinicopathologic entity in which there is obstruction of the sinus cavity outflow tract, resulting in expansion of the sinus walls. The histologic features are quite nonspecific, requiring clinical, radiologic, and pathologic correlation. Most of these lesions result from increased pressure in the sinus due to sinus outlet obstruction, usually as...
