Nasal airflow patterns in a patient with septal deviation and comparison with a healthy nasal cavity using computational fluid dynamics

open access: yesFrontiers in Mechanical Engineering, 2022
Background and objective: Causes for nasal airway obstruction (NAO) are many but septum deviation is the most prevalent etiology. A deviated septum affects the airflow dynamics in the human nasal cavity, which in turn affects the physiological functions ...

Rapid Maxillary Expansion Has a Beneficial Effect on the Ventilation in Children With Nasal Septal Deviation: A Computational Fluid Dynamics Study

open access: yesFrontiers in Pediatrics, 2022
Nasal septal deviation (NSD) is one of the most common nasal diseases. Different from common clinical examination methods, computational fluid dynamics (CFD) can provide visual flow information of the nasal cavity.

Nasality Changes With Age in Normal Korean-Speaking Adults [PDF]

open access: yesClinical and Experimental Otorhinolaryngology, 2019
Objectives This study was performed to investigate the effects of aging on nasality and the influence of age-related changes in nasal cavity volume and nasal patency on nasality. Methods A total of 180 healthy Korean-speaking adult volunteers, who had no

Factors influencing drug deposition in the nasal cavity upon delivery via nasal sprays

open access: yesJournal of Pharmaceutical Investigation, 2020
Background In nasal drug delivery system, nasal spray seems to be the most promising delivery method for both local and systemic diseases therapy. Nasal deposition behavior is the most basic and important process for nasal sprays, which is related to ...

Characterization of the Airflow within an Average Geometry of the Healthy Human Nasal Cavity

open access: yesScientific Reports, 2020
This study’s objective was the generation of a standardized geometry of the healthy nasal cavity. An average geometry of the healthy nasal cavity was generated using a statistical shape model based on 25 symptom-free subjects.

Friend or Foe: Interbacterial Competition in the Nasal Cavity

open access: yesJournal of Bacteriology, 2020
Like other microbes that live on or in the human body, the bacteria that inhabit the upper respiratory tract, in particular the nasal cavity, have evolved to survive in an environment that presents a number of physical and chemical challenges; these ...

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 ...
