Although a variety of theories have been proposed about functions of the paranasal sinuses, not one is clear today. Nonetheless, paranasal sinus-related diseases are associated with a high rate of morbidities. Therefore, it is essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool displaying anatomic variations and diseases....

BACKGROUND & OBJECTIVE Radiation usually results in paranasal sinusitis in nasopharyngeal carcinoma (NPC) patients, which influences patients' quality of life. This study was to explore the occurrence and influencing factors of paranasal sinusitis in NPC patients before and after radiotherapy. METHODS Clinical data of 381 NPC patients, treated in Cancer Center of Sun Yat-sen University from J...

The paranasal sinus system of horses is complex, comprising six pairs of sinuses. Disease processes that can develop in the sinuses include ethmoid hematomas, cysts, neoplasia, and bacterial and fungal infections. Horses that develop paranasal sinus disease vary widely in age. A significant number of clinical conditions involving the paranasal sinuses require a combination of diagnostic tests t...

INTRODUCTION Anatomic variations of the paranasal sinuses are very common. The paranasal sinus anatomy should be carefully examined prior to performing endoscopic sinus surgery in terms of both existent pathologies and anatomic variations. The anatomy of the paranasal sinuses and its variations have gained importance, along with advances in coronal paranasal sinus computed tomography and extens...

Paranasal sinus anatomical anomalies with unknown etiology are common. Paranasal sinus–related diseases are associated with so high rate of morbidities, it becomes essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool in displaying its anatomy, any anatomic variations and diseases. As paranasal sinus development is a comple...

Objective. To investigate the clinical features of paranasal sinus osteomas and to estimate the growth rate of these tumors in a large series of patients. Design. Case series with chart review. Setting. University hospital, tertiary referral center. Subjects and Methods. The authors retrospectively reviewed the paranasal sinus tomography scans that were taken between January 1997 and April 2008...

BACKGROUND The association between diabetes and paranasal sinus disease has not been thoroughly investigated. METHODS We cross-sectionally investigated the association between diabetes and the presence of paranasal sinus disease, which was confirmed by a head MRI scan in 1350 adults who underwent a health screening program focusing on brain diseases and metabolic syndrome. Logistic regression...

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...
