Open housing drives the expression of immune response genes in the nasal mucosa, but not the olfactory bulb. [PDF]

PLoS ONE, 2017
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 ...

Movement of cerebrospinal fluid tracer into brain parenchyma and outflow to nasal mucosa is reduced at 24 h but not 2 weeks post-stroke in mice

Fluids and Barriers of the CNS, 2023
Background Recent data indicates that cerebrospinal fluid (CSF) dynamics are disturbed after stroke. Our lab has previously shown that intracranial pressure rises dramatically 24 h after experimental stroke and that this reduces blood flow to ischaemic ...

Computed tomographic Assessment of Lateral Lamella of Cribiform Plate and Comparison of Depth of Olfactory Fossa

Journal of Nepal Medical Association, 2010
INTRODUCTION: Endoscopic sinus surgery is an upcoming branch in rhinological practice but with some major risks since it has to play around the skull base area. Lateral lamella of cribriform plate is the thinnest area of the skull base.

A computed tomography assessment of olfactory fossa depth in relation to Functional endoscopic sinus surgery in a South African population

Translational Research in Anatomy, 2022
Introduction: The olfactory fossa is a region of the anterior skull base vulnerable to injury during Functional endoscopic sinus surgery, being at the highest risk if deep or asymmetric.

Intracranial pressure elevation alters CSF clearance pathways

Fluids and Barriers of the CNS, 2020
Background Infusion testing is a common procedure to determine whether shunting will be beneficial in patients with normal pressure hydrocephalus. The method has a well-developed theoretical foundation and corresponding mathematical models that describe ...

EVALUATION OF THE DOSE DUE TO THE POSITION OF THE PROTECTION BLOCKS USED TO PROTECT THE EYES.

Brazilian Journal of Radiation Sciences, 2014
Several techniques have been proposed to perform the radiation treatment of medulloblastoma. However, each method presents limitations, and problems have occurred during irradiation due to the application of non-coplanar fields, such as the joint ...

Parainfectious vasculitis due to Pneumococcal meningitis following traumatic CSF rhinorrhoea resulting in cerebellar infarction

Asian Journal of Medical Sciences, 2020
Parainfectious vasculitis is a rare life threatening complication of Streptococcus pneumoniae (S.pneumoniae) meningitis. There is a 19% risk of developing meningitis in the patients with cerebrospinal fluid (CSF) rhinorrhoea.

The Route by Which Intranasally Delivered Stem Cells Enter the Central Nervous System

Cell Transplantation, 2018
Intranasal administration is a promising route of delivery of stem cells to the central nervous system (CNS). Reports on this mode of stem cell delivery have not yet focused on the route across the cribriform plate by which cells move from the nasal ...

The olfactory groove schwannoma attached to the cribriform plate: a case report. [PDF]

Brain Tumor Res Treat, 2015
The olfactory groove schwannoma is a quite rare tumor. We report a case of a 49-year-old woman with an olfactory groove schwannoma attached to the cribriform plate without olfactory dysfunction. She had no specific neurological symptoms other than a headache, and resection of the tumor showed it to be a schwannoma.

Assessment of ethmoid roof and olfactory fossa variations using Keros classification in a tertiary care hospital

The Egyptian Journal of Otolaryngology, 2022
Background Functional endoscopic sinus surgery is a common surgery done in otorhinolaryngology, but it is also riddled with complications. The most dangerous complication is the injury to the skull base leading to cerebrospinal fluid leak, meningitis or ...
