Abstract: (9 Views)
Background: Obstruction of the upper airways may lead to dental and skeletal changes. Nasal septal deviation (NSD) and concha bullosa (CB) are associated with nasal airway obstruction. Mouth breathing is also linked to alterations in maxillary growth and palatal dimensions. This study aimed to compare palatal dimensions in Iranian individuals with and without NSD and CB using cone-beam computed tomography (CBCT).
Methods: This retrospective study analyzed 204 CBCT scans obtained with a large field of view. Scans were categorized into four groups based on the presence or absence of CB and NSD. The deviated septal curve angle (DSCA), palatal inter-alveolar length (PIL), palatal arch depth (PAD), and maxillopalatal arch angle (MPAA) were measured. Group comparisons were performed using one-way ANOVA, followed by post hoc pairwise tests.
Results: presence of CB was significantly associated with changes in mean PIL in both males and females (P=0.02). Only mean PIL showed significant sex differences, being longer in males than females (P=0.01). No significant differences in palatal dimensions were observed between individuals with and without NSD. The four groups differed significantly in mean PIL, MPAA, and DSCA (P<0.05).
Conclusion: CB may significantly alter palatal dimensions and could be associated with skeletal malocclusion. No significant differences in palatal depth and length were found between individuals with and without NSD.
