The characteristics of the paranasal sinuses (maxillary, frontal, sphenoid and ethmoid sinuses) are information great relevance to Forensic Sciences, as their images can be used for human identification purposes. Due particularities, provide valuable identification, reducing risk errors during investigation by experts. Such structures visualized from several imaging exams. This study evaluates ...

The aims of this study are to determine the intra-observer and inter-observer agreement between the two radiologists when reporting the Waters view and 3 views series of the paranasal sinus radiographs. To also determine whether a single Waters view is adequate for diagnostic purpose of sinusitis. 90 sets of paranasal sinuses radiographs were reported by two radiologists independently. The resu...

Malignant lymphoma of the paranasal sinuses and nasal cavity is very rare and can mimic those of infectious, non-lymphomatous neoplastic and granulomatous process in their initial presentation, thus delaying its diagnosis. This report describes a case of unilateral frontal sinus B-cell lymphoma presenting as Pott's puffy tumour. Key features to differentiate the two conditions are discussed. A ...

Recognized since ancient times by Hippocrates, juvenile angiofibroma is an uncommon, benign and extremely vascular tumour that arises in the tissues within the sphenopalatine foramen. Rarely, it is found at other sites in the nasal cavity and paranasal sinuses. Juvenile angiofibroma accounts for less than 0.5 percent of all head and neck tumours. It develops almost exclusively in adolescent mal...

INTRODUCTION A patients with undiagnosed type II diabetes mellitus presented with infective rhinocerebral mucormycosis. INVESTIGATION RESULTS: Initial magnetic resonance imaging scans demonstrated an aggressive disease process involving the left orbit and paranasal sinuses. A repeated scan following treatment excluded intracranial spread or recurrence. Pus from the paranasal sinuses grew Rhizop...

A paranasal sinus mucocele is an epithelial-lined, mucus-containing sac that completely fills the and forms expandable cystic structure. It most commonly affects frontal ethmoidal sinuses, rarely maxillary sphenoid sinuses. Orbital displacement or external disfigurement resulting from expansion of ethmoid sinuses common; however, facial asymmetry caused by bone remodeling rare. We describe a ca...

The bovine paranasal sinuses are a group of complex cavernous air-filled spaces, lined by respiratory epithelium, the exact function of which is unclear. While lesions affecting these sinuses are occasionally reported in cattle, their microbial flora has not been defined. Furthermore, given that the various bacterial and viral pathogens causing bovine respiratory disease (BRD) persist within he...

INTRODUCTION The mucosal malignant melanoma (MM), represent a rare group of tumors (0.2%--8% of all MM), with predominant localization on the mucosal surface of head and neck region, where the localization on the mucosa of nasal cavity, paranasal sinuses and oral cavity are the most common. The mucosal MM within the nose and paranasal sinuses represent approximately 4% of all malignant tumors i...

The aim of this study was to (a) detect the prevalence of anatomical variations of nose and paranasal sinuses in Chronic Rhinosinusitis (CRS) on ‘Nasal Endoscopy’,and‘Computed Tomography’, (b) correlate between the two investigation modalities and (c) study association of anatomical variations of nose and paranasal sinuses in Chronic Rhinosinusitis. This Cross sectional study was carried out at...
