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 ...

INTRODUCTION Osteomas are slow- growing, benign tumors. They are the most common neoplasms of the paranasal sinuses. They are usually originates from the frontal and ethmoid sinus and much less frequently seen in the maxillary and sphenoid sinuses. Although the lamina papyracea is a part of ethmoid bone, a giant osteoma originated from the lamina papyracea is very uncommon. An osteoma of the pa...

Disorders of the paranasal sinuses, particularly the sphenoid sinus, can be associated with significant disorders of the optic and other cranial nerves. We examined 100 consecutive routine CT scans, 100 posterior fossa CT scans, and 100 MR scans to look for evidence of sinus disease, especially of the sphenoid sinus. The sphenoid sinus was abnormal in 7% of scans by all methods. Other sinuses w...

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...

OBJECTIVE To assess the frequency of nodal involvement and its prognostic value in malignant tumors of the paranasal sinuses, particularly in maxillary sinus squamous cell carcinoma. DESIGN Retrospective review. SETTING Tertiary cancer center. PATIENTS The medical records of 704 consecutive patients surgically treated for malignant tumors of the paranasal sinuses from January 1968 to Marc...

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...

Sinus infections are much less common today than they were in the preantibiotic era, but they still are overdiagnosed. Acute sinusitis, a relatively uncommon cause of headache, is the result of infection of one or more of the cranial sinuses. Acute sinusitis usually is characterized by purulent discharge in the nasal passages and a pain profile determined by the site of infection. Sinusitis is ...

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...
