Resumen:
Background: The diagnosis of the respiratory pattern and the analysis of airway dimension using lateral cephalometric radiographs include the study of the adenoid region, free air space of the nasopharynx and oropharynx, soft
palate and posterior part of the tongue. The objective of this study is to identify the airways cephalometric norms
from a sample of Caucasian children, in relation to gender, age and type of malocclusion.
Material and Methods: A total of 480 patients of both sexes were included in the study, the age ranged between
6-12 years. The radiographic records were analyzed using the Nemoceph® 11.3.0 software and the diagnosis of
skeletal class was performed using the Steiner analysis. The cephalometric measurements used for the study were
PNS-AD1, AD1-Ba, PNS-Ba, Ptm-Ba, PNS-H and the upper and lower airways according to McNamara analysis.
The comparative analysis was performed using only upper and lower airways variables.
Results: The mean values for each variable in the total sample were 23.2 mm (PNS-Ad1), 24.7 mm (Ad1-Ba), 47.6
mm (PNS-Ba), 45.7 mm (Ptm-Ba), 30.0 mm (PNS-H), 9.3 mm (upper airway) and 11.5 mm (lower airway). According to gender, all variables were greater...
