background and objective: chronic rhinosinusitis (crs) is one of the most common chronic diseases. in the past decades, there has been an increase in fungal infections of sinuses and fungal rhinosinusitis (frs) has been diagnosed more frequently. knowing the fungal flora and its prevalence in crs patients will allow a better understanding of this disease, permitting a correct diagnosis, treatme...

Selective brain cooling is a system in a human that protects the brain from hyperthermia. Cool venous blood from head skin and upper respiratory tract drains into intracranial dural sinuses. In that region, cool blood in the dural sinuses decreases the temperature of the cerebrospinal fluid. Cerebrospinal fluid provides brain cooling. All cortical arteries to the brain pass the cerebrospinal fl...

BACKGROUND AND PURPOSE The dural venous sinuses in neonates differ from those in adults or older children in that the caliber of venous sinuses is smaller and there is skull molding. The aim of this retrospective study is to evaluate the presence of flow gaps in venous sinuses in neonates on 2D time-of-flight (TOF) MR venography (MRV). METHODS Fifty-one neonates underwent coronal 2D TOF MRV. ...

Dilated venous channels traversing the sella and connecting the two cavernous sinuses were seen on contrast-enhanced MR images in four patients with angiographically proved carotid fistulas. The anatomy and variations of these so-called intercavernous sinuses are discussed and are demonstrated in Latex-injected anatomic specimens. Direct visualization of the intercavernous sinuses on contrast-e...

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...

introduction the maxillary sinuses are the first sinuses form in the embryonic period and begin to be pneumatized from 4 th year of life. sinusitis is a common disease in children and its on–time diagnosis and treatment is very important to prevent relevant side effects. unfortunately, in some medical centers waters' radiography is routinely prescribed for the diagnosis of sinusitis, regardless...

The current work aimed to analyse the anatomical findings of the nasal and paranasal sinuses of the donkey by gross anatomical observation of the skull and cadaver head, cross-sections, sagittal sections and computed tomography (CT) imaging. Seven adult donkeys and ten skulls were used in this study. The donkey head had six pairs of sinuses, three paranasal; the frontal, maxillary, and sphenopa...
