title: Dentofacial morphology and upper respiratory function in 8-10-year-old children.
abstract: OBJECTIVE
  The aim of this preliminary study was to assess the nature of associations between selected dentofacial morphological variables and respiratory mode as measured by percent nasality (%N) as part of an ongoing longitudinal study.
  
  
  METHODS
  Cross-sectional cohort study.
  
  
  METHODS
  The Pediatric Clinical Study Center, Children's Hospital, Columbus, OH. Ninety-eight normal children were tested.
  
  
  METHODS
  Normal variation in %N.
  
  
  METHODS
  Selected dentofacial morphological variables including total and lower anterior face heights, face width, and palatal arch width and %N were estimated.
  
  
  RESULTS
  Small associations between morphologic features and respiratory mode were found, but none were statistically significant.
  
  
  CONCLUSIONS
  No evidence exists for the classic association between 'mouth breathing' and the stereotype of the 'adenoid facies'.
