Abstract

Introduction: Nasal septal deviation (NSD) and concha bullosa (CB) are associated with airway obstruction in mouth breathers. Mouth breathing is associated with alterations in maxillary growth and palatal architecture. The aim of our study was to determine the efect of the presence of CB and NSD on the dimensions of the hard palate using conebeam computed tomography (CBCT). Materials and methods: A retrospective study was conducted using CBCT scans of 200 study subjects. The study subjects were divided into four groups based on the presence of CB and NSD. Septal deviation angle (SDA), palatal interalveolar length (PIL), palatal depth (PD) and maxillopalatal arch angle (MPAA) were measured in the study groups. Results: The presence of NSD and CB was associated with signifcant (p<0.001) diferences in the palatal dimensions of the study subjects. The PIL and MPA (p<0.001) were signifcantly reduced (p<0.001), whereas the PD was signif‑ cantly increased (p<0.001) in study subjects with NSD and CB. There was no signifcant change in the palatal dimen‑ sions between the unilateral and bilateral types of CB. Among the palatal dimensions, the PIL had the most signifcant association (R2=0.53) with SDA and CB. There was a signifcant correlation between the palatal dimensions and SDA when CB was present along with NSD. Conclusion: Based on the results of this study, it can be concluded that the presence of NSD and CB have a signif‑ cant efect on the palatal dimensions and, therefore, they may be associated with skeletal malocclusion.
