Factorial analysis of sagittal cephalometric measurements of the upper airways (original) (raw)

Revista Mexicana de Ortodoncia, 2019

Abstract

There are different cephalometric measurements to evaluate the dimensions of the upper airways using a lateral headfilm. It is unknown how many characteristics are possible to study from the available measurements and which are the most useful measurements for this purpose. Objective: To identify factors of measurement of the upper airways and determine their association to craniofacial dimensions. Material and methods: Cross-sectional study. We analyzed lateral headfilms and performed a principal factor analysis for upper airways measurements: N-S-Ba, BaS-PNS, AD1, AD2, PTV to Adenoid (DPTV) and Airway % (A%). Results: We analyzed 151 records, without previous orthodontic treatment or craniofacial syndrome. We identified two principal factors: Factor 1 (F1) includes AD1, AD2, DPTV and A%, and factor 2 (F2) includes Na-S-Ba and Ba-S-PNE. Conclusions: F1 was related to linear dimensions and F2 to structural characteristics.
