Physical and geometric constraints explain the labyrinth-like shape of the nasal cavity [PDF]

open access: yes, 2017
The nasal cavity is a vital component of the respiratory system that heats and humidifies inhaled air in all vertebrates. Despite this common function, the shapes of nasal cavities vary widely across animals. To understand this variability, we here connect nasal geometry to its function by theoretically studying the airflow and the associated scalar ...

Basaloid Squamous Cell Carcinoma in Nasal Cavity [PDF]

open access: yesClinical and Experimental Otorhinolaryngology, 2009
Basaloid squamous cell carcinoma (BSCC) is often founded in the head and neck region. However, BSCC in the sinonasal tract is rare. We report here on the case of a 58-yr-old woman who presented with nasal obstruction and epistaxis.

PHYSIOLOGIY OF NASAL CAVITY

open access: bronzeNippon Jibiinkoka Gakkai Kaiho, 1964
An attempt was made to explain the reason why the temperoture and humidity of the inspired air in the nasal cavity rise, by applying the theory of alternating contact between water and air.From these considerations it was concluded that the heat and the humidity of the air in the nasal cavity rise pattly due to the moisture of the exspired air ...

Patient specific numerical simulation of flow in the human upper airways for assessing the effect of nasal surgery [PDF]

open access: yesarXiv, 2017
The study is looking into the potential of using computational fluid dynamics (CFD) as a tool for predicting the outcome of surgery for alleviation of obstructive sleep apnea syndrome (OSAS). From pre- and post-operative computed tomography (CT) of an OSAS patient, the pre- and post-operative geometries of the patient's upper airways were generated ...

ONCOCYTOMA OF THE NASAL CAVITY

open access: yesJournal of Nepal Medical Association, 2003
Oncocytoma of the nasal cavity is an extremely rare condition with only a few cases reported in the literature. A case of oncocytoma of the nasal cavity in a 12 years old Nepali boy is presented along with a brief review of the relevant literature.

Effects of decongestion on nasal cavity air conditioning efficiency: a CFD cohort study [PDF]

open access: yesScientific Reports
Decongestion reduces blood flow in the nasal turbinates, enlarging the airway lumen. Although the enlarged airspace reduces the trans-nasal inspiratory pressure drop, symptoms of nasal obstruction may relate to nasal cavity air-conditioning.

A CASE OF SINO-NASAL MALIGNANT MELANOMA [PDF]

open access: yesTrakia Journal of Sciences, 2022
Mucosal melanomas are rare malignant neoplastic disease, that originates from melanocytes in mucosal tissue. It is a tumor mass of the nasal cavity or paranasal sinuses and most commonly originates from the nasal septum, nasal turbinates, or lateral ...

Clinical, anatomopathological and immunohistochemical findings of a transitional cell carcinoma from nasal cavity, frontal and ethmoidal sinus with meningoencephalic invasion in a dog [PDF]

open access: yesOpen Veterinary Journal, 2021
Background: Primary neoplasms of the nasal cavity and sinuses are uncommon in domestic animals, most of which are of epithelial origin, being adenocarcinoma the most common tumor diagnosed in this region.
