Passive smoking significantly impacts nasal mucociliary clearance (MCC), increasing clearance time. Both active and passive smoking impair nasal MCC compared to healthy individuals.
Area of Science:
- Otorhinolaryngology
- Environmental Health
- Respiratory Physiology
Background:
- Nasal mucociliary clearance (MCC) is a critical defense mechanism in the upper airways.
- Exposure to environmental tobacco smoke, including passive smoking, is a growing public health concern.
- Understanding the impact of passive smoking on nasal MCC is essential for otorhinolaryngology practice.
Purpose of the Study:
- To investigate the relationship between passive smoking and nasal mucociliary clearance (MCC).
- To compare nasal MCC in passive smokers, active smokers, and healthy controls.
Main Methods:
- A cross-sectional study was conducted with three groups: passive smokers, active smokers, and healthy controls.
- Nasal MCC time was assessed for all participants.
- Smoking history was collected through patient questionnaires.
Main Results:
- Passive smoking significantly increased nasal MCC time compared to healthy controls (12.6 ± 4.67 vs. 6.4 ± 1.55, P < .01).
- Active smoking also significantly increased nasal MCC time compared to healthy controls (23.59 ± 12.41 vs. 6.4 ± 1.55, P < .01).
- A statistically significant difference in MCC values was observed between passive smokers and active smokers (P < .01).
Conclusions:
- Passive smoking demonstrably affects nasal mucociliary clearance.
- Both active and passive smoking lead to prolonged nasal MCC times relative to healthy individuals.
- Findings highlight the detrimental effects of secondhand smoke on nasal physiological functions.

Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
