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 effect of the presence of CB and NSD on the dimensions of the hard palate using cone-beam 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 significant (p < 0.001) differences in the palatal dimensions of the study subjects. The PIL and MPA (p < 0.001) were significantly reduced (p < 0.001), whereas the PD was significantly increased (p < 0.001) in study subjects with NSD and CB. There was no significant change in the palatal dimensions between the unilateral and bilateral types of CB. Among the palatal dimensions, the PIL had the most significant association (R2 = 0.53) with SDA and CB. There was a significant 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 significant effect on the palatal dimensions and, therefore, they may be associated with skeletal malocclusion.

The palatal interalveolar length (PIL) is the distance between the mid-centres of the cervical portion of the available tooth, from one side to the other. If there was no tooth, then the mid-centre of the alveolar bone near the crest was considered the reference point. Palatal arch depth (PAD) is the length of the line from "P" (junction of the nasal septum and hard palate) to the interalveolar line. The maxillopalatal arch angle (MPAA) is the angle that is formed by the lines from "P" to both points of the mid-centre of the available tooth or the midpoint maxillary alveolar bone for patients missing teeth
