Computed tomography scans of paranasal sinuses before functional endoscopic sinus surgery

Computed tomography scan of rhinosinusitis, current practice, and requirements for endoscopic surgery of paranasal sinuses.

OBJECTIVE To evaluate the current practice in requesting and performing paranasal sinuses CT scan for patients scheduled for endoscopic sinus surgery, and to describe the current hospitals practice in performing these scans. METHODS This cross-sectional questionnaire study was conducted in the King Hussein Medical Center, Amman, Jordan between April and May 2010. Three forms were designed to ...

Comparison of Olfactory Function before and After Endoscopic Sinus Surgery

Introduction: Olfactory loss in patients with chronic rhinosinusitis has been measured by different methods. However, the results have been variable, and it is not clear whether endoscopic sinus surgery significantly improves olfactory function. This study was performed to evaluate the influence of endoscopic sinus surgery on olfactory function in patients with chronic rhinosinusitis.  Material...

A systematic approach to the interpretation of computed tomography scans prior to endoscopic sinus surgery.

Computed tomography (CT) provides an excellent map for the sinus surgeon as well as providing information about the extent of disease and the presence of bony destruction. Surgeons need to be aware of the anatomical configuration of the sinuses and the presence of any structural changes such as a dehiscent lamina papyracea, asymmetric skull base, low level of posterior skull base or an Onodi ce...

Anatomic Reference for Computed Tomography of the Paranasal Sinuses and Their Openings in the Rayini Goat

Objective-  to provide a reference anatomy of the paranasal sinuses of the goat by using computed tomographic modality. Design- Experimented study.   Animals- Five male Rayini goats.   Procedures- CT images were acquired from the head region perpendicular to the hard palate. CT windows were adjusted as necessary to  obtain the optimal image for the paranasal sinuses. The images were studie...
