  • Title: Acoustic rhinometry in the evaluation of children with nasal or oral respiration.
    Author: Zavras AI, White GE, Rich A, Jackson AC.
    Journal: J Clin Pediatr Dent; 1994; 18(3):203-10. PubMed ID: 8054306.
    Abstract:
    The purpose of this study was to determine if there are any differences in the nasal geometry of children with nasal respiration or predominantly oral respiration (mouth breathing). The technique utilized was the acoustic reflection technique or acoustic rhinometry. Acoustic rhinometry is a non-invasive method, which can be easily applied to young children. Twenty children participated and both nostrils were evaluated. Statistically significant differences were found in the total nasal volumes between the two groups, with the mouth breathers presenting with reduced nasal volumes. No differences were observed in the nasal cross sectional areas.
