title: Two-year follow-up with acoustic rhinometry in children.
abstract: BACKGROUND
  This is an explorative study of growth-related nasal geometry in healthy children.
  
  
  METHODS
  A total of 88 girls and boys between the ages of 4 and 16 years were followed over a period of 2 years by acoustic rhinometry. The registrations were correlated to height at each occasion.
  
  
  RESULTS
  Although both the minimal cross-sectional area and the nasal volume increased in all age groups over 7 years, large individual variations in nasal geometry led to a weak relationship with growth.
  
  
  CONCLUSIONS
  In the undecongested nasal cavity in children, correlation of nasal geometry makes sense for height but not for age.
