Age and gender effects on nasal respiratory function in normal subjects
1Dental Medicine Research Office, School of Dental Medicine, University of Pittsburgh, Pennsylvania.
Summary
This study establishes normative nasorespiratory data for individuals aged 5-73, revealing age and gender impacts on nasal airflow and breathing patterns. These findings aid in diagnosing breathing disorders and defining normality.
Area of Science:
- Otolaryngology
- Respiratory Physiology
- Craniofacial Biology
Background:
- Understanding normal nasorespiratory function is crucial for diagnosing breathing impairments.
- Establishing normative data is essential for differentiating between normal and abnormal breathing patterns.
- Age and gender can influence nasorespiratory characteristics.
Purpose of the Study:
- To determine normative values for nasal resistance, nasal cross-sectional area, and respiratory mode in healthy individuals.
- To investigate the effects of age and gender on these nasorespiratory parameters.
- To provide data that aids in clinical diagnosis and treatment decisions for various craniofacial conditions.
Main Methods:
- Posterior rhinomanometry was used to directly measure nasal resistance.
- The SNORT technique was employed to determine respiratory mode during quiet breathing.
- Nasal cross-sectional area was estimated using the hydrokinetic equation.
Main Results:
- Significant effects of age were observed across all measured nasorespiratory variables.
- Gender differences were significant for respiratory mode.
- Weak correlations were found between respiratory mode and nasal resistance.
Conclusions:
- The study provides valuable normative data for nasorespiratory characteristics in a wide age range.
- Findings highlight the influence of age and gender on nasal airflow and breathing patterns.
- The data can assist clinicians in diagnostic and treatment planning for individuals with normal and abnormal craniofacial morphology.
