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 ...

Metastasizing esthesioneuroblastoma in a dog [PDF]

, 2014
A 7-year-old Afghan hound presented with a history of disorientation, loss of vision, and seizures. Magnetic resonance imaging helped identify a mass at the level of the main olfactory bulb that compressed and displaced adjacent tissues in the cribriform

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 ...

Optimum imaging and diagnosis of cerebrospinal fluid rhinorrhoea [PDF]

, 2000
Imaging is an important component in the investigation of unilateral watery rhinorrhoea suspicious of cerebrospinal fluid (CSF). Whilst the demonstration of the presence of beta 2 transferrin confirms that CSF is present it may prove difficult to ...

Resolution of Pulmonary Inflammation and Obstruction Following Repair of Cerebrospinal Fluid Leak: A Case Report and Review of the Literature. [PDF]

Case Rep Pulmonol
Objectives Cerebrospinal fluid (CSF) rhinorrhea involves drainage of CSF through the nasal cavity due to disruption of the skull base, and pneumonitis secondary to CSF aspiration is a lesser‐known complication reported. We present the case of a patient whose pulmonary symptoms and function improved after surgical CSF leak repair. Methods This is a case

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.

Computed tomography assessment of the ethmoid roof: a relevant region at risk in endoscopic sinus surgery [PDF]

, 2008
OBJECTIVE: To evaluate the olfactory fossae depth according to the Keros' classification and determine the incidence and degree of asymmetry in the height and contour of the ethmoid roof.

Biphenotypic Sinonasal Sarcoma-Case Report and Review of Clinicopathological Features and Diagnostic Modalities. [PDF]

, 2019
Background Biphenotypic sinonasal sarcoma is a recently described malignancy showing dual differentiation with both myogenic and neural elements. Due to its histologic similarities to other sinonasal malignancies, it is a diagnostic challenge.

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.
