Objectives:
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.
Design:
Cross-sectional cohort study.
Setting And Sample Population:
The Pediatric Clinical Study Center, Children's Hospital, Columbus, OH. Ninety-eight normal children were tested.
Experimental Variable:
Normal variation in %N.
Outcome Measure:
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.
Conclusion:
No evidence exists for the classic association between 'mouth breathing' and the stereotype of the 'adenoid facies'.
