Ventilation of the Paranasal Sinuses Studied With Dynamic Emission Computer Tomography

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...

Disorders of the Paranasal Sinuses

Inflammation of the equine paranasal sinuses is a relatively uncommon disease that may be caused by primary bacterial or mycotic infections (Mason 1975a), or can be secondary to dental disease (van der Velden & Verzijlenberg 1984, Scott 1987, Tremaine & Dixon 2001a), facial trauma, sinus cysts, progressive ethmoid hematoma or sinonasal neoplasia (Mansmann & Wheat 1973, Gibbs & Lane 1987, Tremai...

Mucoceles of the paranasal sinuses.

Actinomycosis of the paranasal sinuses.

Actinomycosis is a chronic suppurating granulomatous disorder specific to soft tissue. It is produced by Actinomyces Israelii, gram positive anaerobic bacteria that are very difficult to culture, and a commensal saprophyte of the oral cavity (tonsillar crypts, saliva and gingival dental sulci) and the gastro-intestinal tract; it becomes a pathogen in the face of erosions of the oropharyngeal mu...

Assessing the prevalence of paranasal sinuses anatomical variants in patients with sinusitis using Cone Beam Computer Tomography

BACKGROUND AND AIMS To asses, by using the Cone Beam CT (CBCT) reformatted images, the presence of anatomical variants of the sinonasal cavities and to determine the correlation of these variations with the onset of maxillary sinus inflammations. METHOD The study is a retrospective one and consists of the investigation of 130 patients with CBCT imaging, patients that were referred to the Maxi...
