Abstract
Objectives. To study the dynamic behaviour of the nasal mucosa in neonates.Method. Although the nasal cycle has been described in adults,1 studies regarding the nasal cycle physiology in neonates are scarce. Acoustic rhinometry (RHIN 2000 miniprobe) was carried out in ten neonates over periods ranging from 165 to 255 min at 15‐min intervals. Inclusion criteria were babies with no upper airway symptoms and no abnormality on anterior rhinoscopy. All examinations were carried out by the same examiner under similar conditions. The minimum cross sectional area (MCA10–40) and volume of nasal cavity (Vol10–40) were analysed for correlation using the Pearson's correlation coefficient.Results. Correlation (alternating pattern) between the right and left sides was found to be significant in one baby.Conclusions. Ninety percent of the neonates we examined did not demonstrate a nasal cycle. We demonstrated an alternating pattern in one baby. Neonates probably do not have a nasal cycle as demonstrated in adults.Reference. 1 Fisher E.W., Scadding G.K. & Lund V.J.
