This study establishes normal nasal resistance values for children aged 4-16 using rhinometry. These findings provide crucial pediatric reference points for diagnosing nasal obstruction.
Area of Science:
- Otolaryngology
- Pediatric Medicine
- Respiratory Physiology
Background:
- Nasal airway patency assessment is crucial for diagnosing pediatric obstructive conditions.
- Existing normal nasal resistance data is limited for pediatric age groups.
- Objective rhinometric data is needed for children aged 4-16.
Abstract:
Rhinometry has provided a quantitative and objective means of assessing nasal airway patency. Previous investigators have established normal nasal resistances for adults and newborn infants. Less material and no such normal references are available for the pediatric ages. In this study, nasal airway resistance is assessed by anterior rhinometric technique in 498 children ranging from four to 16 years of age. Collected nasal resistance data are found to vary inversely with age and fall in an almost linear fashion between already established normals of infancy and adulthood. As far as we can determine, pediatric age specific nasal resistance data with calculated standard deviations and 95% confidence levels have not been previously reported. Such data provides initial age specific reference points enabling the rhinologist to more objectively evaluate concerns regarding nasal obstructive problems in children.
