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...

Chronic Inflammatory Disease of Na- sal Cavity and Paranasal Sinuses

In this chapter, we examine the chronic inflammatory diseases of the nasal cavity and paranasal sinuses. First, we examine the basic characteristics of the various chronic inflammatory diseases of the nasal cavity and paranasal sinuses and chronic inflammatory diseases of the oral cavity. Further, we discuss the etiopathogenesis, diagnosis, differential diagnosis, and treatment options for the ...

Image Optimization and reduction of radiation dose in CT of the paranasal sinuses

Introduction: Since demand for computed tomography (CT) examinations is growing, patients are exposed more frequently to ionizing radiation. To reduce the dose delivered to patients in each scan, CT technologists can change the image acquisition parameters. However, this reduces image quality. Present study aimed to optimize and reduce radiation dose in a CT of the paranasal si...

The Role of Transforming Growth Factor Beta 1 (TGFβ1) in Nasal and Paranasal Sinuses Polyposis

  Background and Objectives: Nasal polyposis is a diseases resulting from complex pathogenetic mechanisms. Some studies showed that TGFβ1 had significant role in this pathogenesis. In this study, we investigated the roe of cytokines and mediators in polyp development. Material and Methods: In this case- control study, healthy nasal mucosal samples were obtained from 24 peopl...
