The effect of the nasal cycle on mucociliary clearance

Clinical Otolaryngology and Allied Sciences, 1999
The nasal cycle is a well-recognised physiological phenomenon where each side of the nose alternates through phases of congestion and decongestion. Although many physiological properties of the nose alternate with the nasal cycle whether this has any effect on the nasal mucociliary clearance is less clear.

The effect of COVID-19 on nasal mucociliary clearance

Acta Oto-Laryngologica, 2022
The impacts of coronavirus disease-2019 (COVID-19) on nasal mucociliary clearance (MCC) have shown conflicting results.The aim of this study was to determine whether COVID-19 infections affect nasal mucociliary activity using the saccharin test to measure nasal MCC time.This prospective comparative investigation included 25 patients with COVID-19 ...

Primary Ciliary Dyskinesia and Nasal Mucociliary Clearance

Respiration, 2009
In this study, nasal mucociliary clearance is investigated in patients with primary ciliary dyskinesia, patients with other respiratory tract infections and healthy persons. Mucociliary clearance is established with a drop of albumen labelled with 99m-Tc.

Nasal mucociliary clearance in total laryngectomized patients

European Archives of Oto-Rhino-Laryngology, 2006
We measured the nasal mucociliary activity in total laryngectomy patients, and to compare among themselves, smokers, diabetics and normal population besides that to investigate the short and long term effects of total laryngectomy on nasal mucosa. The study includes 39 patients who had total laryngectomy between the January 1998-August 2005 and 36 ...

Nasal mucociliary clearance and hearing loss in pseudoexfoliation syndrome

European Archives of Oto-Rhino-Laryngology, 2021
To evaluate nasal mucociliary clearance (NMC) and hearing loss in patients with pseudoexfoliation (PEX) syndrome.The study included 36 patients with PEX syndrome as the study group, and 39 healthy individuals as the control group. The duration of NMC was measured using the saccharine test.

Nasal Mucociliary Clearance Under Various Conditions

Acta Oto-Laryngologica, 1983
We applied the tagged-particle method or the saccharin method or both to the nasal mucociliary clearance. There was no effect of ageing on the transport time of saccharin in control subjects of ages under 60, and 70% of control subjects of ages more than 60 had the same transport time as that obtained in younger control subjects.

The effect of vidian neurectomy on nasal mucociliary clearance

The Journal of Laryngology & Otology, 1988
AbstractThe physiological factors controlling mucociliary transport are largely unknown. Nasal mucociliary clearance was measuredusing the saccharin test in seven patients who had previously undergone vidian neurectomy for vasomotor rhinitis. Persistent denervation was suggested by impaired tear secretion.

Nasal mucociliary clearance after radiation therapy

The Laryngoscope, 1995
AbstractIrradiation has been demonstrated to cause decreased mucociliary clearance in animal models. We sought to verify this effect clinically by using the saccharin transport test to evaluate nasal mucociliary clearance in 9 patients previously treated with radiation therapy to the nasal cavity.

Nasal mucociliary clearance in man.

Ciba Foundation symposium, 1978
Nasal mucociliary clearance was measured in healthy young human subjects and tracheal clearance in the experimental animal under a wide variety of conditions. There is a broad range of clearance rates whether at standard ambient conditions (23 degrees C, 50% relative humidity) or in the face of a number of environmental variables.

Impaired Nasal Mucociliary Clearance in Long-Distance Runners

International Journal of Sports Medicine, 1995
For years physicians have observed a high incidence of upper respiratory tract infections (URTI) after strenuous exercise. Mucosal surfaces represent a first-line-of-defense against infections, and pollutants or organisms entrapped in respiratory secretions are cleared by mucociliary transport. Little is known about this mechanism during exercise.
