PURPOSE The aim of this study was to investigate paranasal sinus pathoses detected on cone-beam computed tomography (CBCT) in an adult population. PATIENTS AND METHODS Three observers retrospectively inspected 353 consecutive CBCT scans obtained in a dentomaxillofacial radiology department for paranasal sinus pathoses. Descriptive statistics and chi-square tests were used to determine the pre...

Foreign bodies (FB) are a common occurrence in the realm of ENT practice. The most commonly involved sites are nasal cavities, ears, and pharynx. Foreign bodies are accompanied by site-related symptoms and do not pose much of a challenge to well-trained physicians. Foreign bodies may be introduced willingly by the patient or by accident. Paranasal sinus foreign bodies are rarely seen, and most ...

OBJECTIVES/HYPOTHESIS To describe surgical outcomes and radiographic features of olfactory groove meningiomas treated by excision through the subcranial approach. Special emphasis is placed on paranasal sinus and orbit involvement. STUDY DESIGN Retrospective review of a series of patients. METHODS Nineteen patients underwent excision of olfactory groove meningioma (OGM) via the transglabell...

OBJECTIVE To evaluate by computed tomographic scanning the paranasal mucosal changes of coal workers with and without pneumoconiosis. METHODS Examination of images and scores from paranasal computed tomographic scans. The study participants were 26 coal workers with pneumoconiosis, 29 coal workers without pneumoconiosis, and 20 controls. All were men. The extent and patterns of inflammatory p...

Homology of virtually all major components of facial anatomy is assessed in Archosauria in order to address the function of the antorbital cavity, an enigmatic structure that is diagnostic for the group. Proposed functions center on its being a housing for a gland, a muscle, or a paranasal air sinus. Homology is approached in the context of the Extant Phylogenetic Bracket method of reconstructi...

Previously, anatomists considered paranasal sinuses as a mysterious region of the human skull. Historically, paranasal sinuses were first identified by ancient Egyptians and later, by Greek physicians. After a long period of no remarkable improvement in the understanding of anatomy during the Middle Ages, anatomists of the Renaissance period-Leonardo da Vinci and Vesalius-made their own contrib...

Background: Chronic rhinosinusitis (CRS) refers to a group of disorders characterized by inflammation of the mucosa of the paranasal sinuses. Computed tomography (CT) scans used as the gold standard diagnostic modality of nose and paranasal sinus diseases. There has been a lot of studies regarding the anatomic variations leading to pathogenesis of paranasal sinus diseases. Considerable progress...

Iatrogenic foreign bodies of the paranasal sinuses are extremely rare and, as a rule, during medical procedures. In this clinical case, fracture needle for puncture maxillary sinus required surgical treatment.
