AIMS: The aims of this study were to examine the cephalometric and airway measurements on children with Sleep Related Breathing Disorders (SRBD) and without SRBD, and to investigate the impact of maxillary expansion on these measurements.
MATERIALS AND METHODS: This observational study utilized data from Boston University Orthodontics Department between 2016 and 2020. Lateral cephalograms, acoustic rhinometry and pharyngometry were obtained at two time points. SRBD was determined by a score of 0.33 or higher according to the Pediatric Sleep Questionnaire. Mann–Whitney U test and Spearman correlation analysis were used to analyze the data. Statistical significance was set at <0.05.
RESULTS: A total of 163 children (61 male, 102 female) were included in this study. Certain airway measurements (Ph Volume p=0.02, Rh air resistance p=0.05, Rh minimum resistance p=0.001) were significantly higher in SRBD group compared to non-SRBD group. In the SRBD group there was a significant negative correlation between Ph Min Distance and SNA (p=0.001), SND (p=0.05), mandibular arc (p=0.03), U1-SN (p=0.02), U1-Apo (p=0.03). Positive. correlations were observed between Ph Volume with L1-NB (p=0.05) and Rh Min Distance Left with Pog- NB (p=-0.5), mandibular arc p=0.05, L1-NB (p=0.01), L1-Apo (p=0.01). Rh Min Cross-sectional left was positive correlated with overbite (p=0.03) and Rh Min cross-sectional right with posterior face height (p=0.05). Certain airway measurements and cephalometric measurements were statistically different across expansion and non-expansion groups (RhVolumeRt p=0.003. RhMinCrossSectionalLft p=0.03, RhMindistanceRt p=0.03, RhAirResistanceRt p=0.05, ANB p=0.0058, S-N (mm) p=0.05, U1 - NA (mm) p=0.04, U-Incisor Protrusion p=0.01, nterincisal Angle p=0.01, Upper Lip - S Line p= 0.005, Upper Lip to E-Plane p=0.01
CONCLUSION: Airway measurements and cephalometric measurements differ significantly between SRBD and non-SRBD subjects. Significant correlations were observed between cephalometric measurements and airway measurements in the SRBD children. Maxillary expansion can be a treatment option for improving certain airway and cephalometric values among those with sleep-disordered breathing.
