Abstract
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'.
