Cavernous sinus thrombosis not only presents with constitutional symptoms including fever, pain and swelling but also with specific findings such as proptosis, chemosis, periorbital swelling, and cranial nerve palsies. It is known to occur secondary to the spread of paranasal sinus infections in the nose, ethmoidal and sphenoidal sinuses. However, paranasal sinus infection of dental origin is r...

Osteomas of the paranasal sinuses are slow-growing, benign tumours most frequently found in the frontal sinus with an incidence that varies from 47% to 80% of the cases; there are often no symptoms and they are diagnosed by chance during an X-ray examination. When there are symptoms, they are usually headaches and ocular or neurological complications. The treatment of choice is surgery. A case ...

OBJECTIVES/HYPOTHESIS To examine the sinus-related sequelae of free flap reconstruction for complex orbitofacial defects. STUDY DESIGN Retrospective chart review. METHODS Demographic, clinical, and radiographic data on a series of 55 patients who had undergone free tissue transfer for orbitofacial reconstruction was retrospectively reviewed. Follow-up of ≥ 3 months was available for 49 pati...

We report a case of a 70-year-old man diagnosed with a respiratory epithelial adenomatoid hamartoma (REAH) of the nasal cavity after a past sinus surgery and associated with nasal polyposis. REAH is a recently described pathologic entity that can present with nasal obstruction, congestion, rhinorrhea, epistaxis, hyposmia, and headaches. It is a rare lesion of nasal and paranasal sinuses, but sh...

PURPOSE Mucoceles are cystic lesions, resulting from an obstruction in the paranasal sinuses and an accumulation of mucus, causing enlargement of the affected paranasal sinus. The signs and symptoms depend on the affected sinus. Treatment consists of surgical resection. The purpose of this study was to describe the clinical presentation of patients with mucocele, and also to describe the surgic...

BACKGROUND The paranasal sinuses and mastoid air cells vary considerably in size and shape from person to person. The main structures are pneumatic. In this study, we investigated the relationship between right and left sides and evaluated the volume changes according to age and sex. METHODS Of all patients attending the radiology department, 91 cases without paranasal sinuses and mastoid air...

The paranasal air sinuses and nasal cavities were studied along with other cephalic spaces (brain cavity, paratympanic sinuses) in certain dinosaurs via CT scanning and 3D visualization to document the anatomy and examine the contribution of the sinuses to the morphological organization of the head as a whole. Two representatives each of two dinosaur clades are compared: the theropod saurischia...

INTRODUCTION Mucoceles are mucus-filled, epithelial-lined sacs that slowly develop in the paranasal sinuses when sinus or concha bullosa drainage is obstructed by inflammatory processes, trauma, or prior surgery. They are extremely rare in children. Symptoms usually arise from the nasal obstruction or compression of neighboring structures. CASE PRESENTATION This case report describes a 5-year...

The relationship between paranasal sinus pneumatization and chronic rhinosinusitis (CRS) without cystic fibrosis is not well understood. Previous investigations have confirmed sinus hypoplasia in cystic fibrosis (CF) patients. This study compares paranasal sinus pneumatization of CRS patients to unaffected controls to determine if there is an analogous effect to that seen in CF. 591 sinus compu...

Background and Objectives: The frontal sinus is regarded as one of the human paranasal sinuses located in the frontal bone as a triangular-shaped cavity, which originates as separated space from the anterior ethmoid cells. Computed Tomography (CT) is a completely non-destructive technique that uses a high density of contrast to identify the air inside any bony sinus with soft tissue demarcated ...
