Tracer studies indicate that cerebrospinal fluid (CSF) transport can occur through the cribriform plate into the nasal submucosa, where it is absorbed by cervical lymphatics. We tested the hypothesis that sealing the cribriform plate extracranially would impair the ability of the CSF pressure-regulating systems to compensate for volume infusions. Sheep were challenged with constant flow or cons...

To increase an awareness of the developmental anatomy of the nasal cavity as it applies to the radiologic work-up of choanal atresia and frontoethmoidal cephaloceles, we report two cases that demonstrate potentially serious imaging pitfalls. Two neonates with nasopharyngeal obstruction were imaged with CT and MR. Both patients had surgically proved bilateral bony choanal atresia. In addition to...

OBJECTIVES/HYPOTHESIS A dural arteriovenous fistula (DAVF) with cortical venous reflux (CVR) is a dangerous neurovascular entity. A DAVF at the cribriform plate is typically silent until its inevitable presentation with intracranial hemorrhage. CASE SUMMARY A 67-year-old male presented with severe epistaxis. Following unsuccessful conventional measures and a surgical exploration, a catheter a...

The authors describe a case of cerebrospinal fluid rhinorrhea due to a congenital defect in cribriform plate, an anomaly that has not been described hitherto. It was successfully treated surgically.

Nasal mucosa and olfactory bulb are separated by the cribriform plate which is perforated by olfactory nerves. We have previously demonstrated that the cribriform plate is permissive for T cells and monocytes and that viruses can enter the bulb upon intranasal injection by axonal transportation. Therefore, we hypothesized that nasal mucosa and olfactory bulb are equipped to deal with constant i...

We report a rare case of nasal glial heterotopia in an adult. After the surgery, frontal lobe cerebral hemorrhage developed. A 58-year-old man had unilateral nasal obstruction that progressed for one year. He had been treated for hypertension, chronic heart failure, and cerebral infarction with aspirin and warfarin. A computed tomography scan showed that the tumor occupied the right nasal cavit...

Free and informed consent was obtained from the child’s mother, and the Research Ethics Committee has approved the present study publication. Computed tomography (CT) demonstrated metopic suture diastasis characterizing hypertelorism, and an empty sella turcica occupied by a cystic image. Magthrough the foramen cecum over the cribriform plate of the ethmoid. The second group includes basal ence...
