“…This may imply mouth breathing following NSD which would be followed by an increase in the depth of the palate bone, deepening the palate and then increasing the volume of the oropharynx, which is located in the middle of the pharyngeal airway between the PNS and the epiglottis. In the study of Saati et al [ 28 ], it was concluded that men’s throat volumes were significantly larger; and NSD had affected the vertical growth pattern of the face [ 28 ]. It was also concluded that the oropharynx was more developed in people diagnosed with NSD compared to individuals without NSD [ 28 ].…”

It was also concluded that the oropharynx was more developed in people diagnosed with NSD compared to individuals without NSD [ 28 ].

“…Patients with nasal obstruction due to NSD might suffer from maxillary width constriction as well as class II malocclusion with increased anterior facial height, bimaxillary retrusion, and increased overjet [ 34 ]. There is no study on the association between the NSD and nasopharynx volume; and there are only 2 recent studies on the associations between NSD and oropharynx, but not nasopharynx, airway volume [ 27 , 28 ]. For being able to fully discuss the findings, more studies are needed.…”

Background Nasal septum deviation (NSD) can cause serious anatomical and clinical complications. It can change the breathing pattern and thus alter the anatomy of the airway structures. Despite its importance, the association between NSD with the nasopharynx volume (NPV) has not been assessed before. Therefore, we aimed to investigate it for the first time. Methods Archival CBCTs of 202 patients older than 17 years and without any history of trauma or pathology of the nasopharynx and without any orthodontic/orthognathic treatments were evaluated (129 women, 73 men, mean age: 36.24 ± 14.61 years). All included CBCTs must have been taken with a 12 × 8 field of view and fully covered the nasopharynx areas. The extent of NSD (°) and NPV (mm3) were measured. NSDs were categorized as mild (NSD ˂ 9°), moderate (9 ≤ NSD ≤ 15°), and severe (NSD ˃ 15°). Associations between sex, age, NSD, and nasopharynx volume were assessed using independent-samples t test, chi-square, one-way ANOVA, Tamhane post hoc test, Pearson and point-biserial correlation coefficients, and multiple linear regressions (α = 0.05). Results Mean NSDs were 11.27 ± 4.69° (range 1–19.5), 11.58 ± 4.63°, and 10.70 ± 4.76° in the sample, females, and males, respectively (P > 0.05). Of females, 27.9%, 40.3%, and 31.8% had mild, moderate, and severe NSDs. These were 35.6%, 39.7%, and 24.7% in males (P > 0.05). Mean NPVs were 4.88 ± 1.49, 4.80 ± 1.43, and 5.04 ± 1.60 mm3 in the sample, females, and males, respectively (P > 0.05). Mean NPVs were 6.41 ± 1.21, 4.87 ± 0.73, and 3.30 ± 0.65 mm3 in mild, moderate, and severe NSD groups (all P values = 0.000). Mean ages were 27.06 ± 6.49, 29.80 ± 9.64, and 54.73 ± 8.45 years in mild, moderate, and severe NSD groups (severe group being older than the other two groups, P = 0.000). NSD was strongly, negatively correlated with NPV (R = − 0.793, P = 0.000). Sex was not correlated with NPV or NSD (P ≥ 0.189). Age was negatively and positively correlated with NPV and NSD, respectively (P = 0.000). Modeling NSD (β = −0.776, P = 0.000) as a predictor for NPV rendered age effect insignificant (P > 0.05). Conclusions It was found, for the first time, that the more deviated the nasal septum, the smaller the nasopharynx volume. Aging might increase NSD and through it, reduce the nasopharynx volume. Sex might not affect NSD or NPV.

The purpose of this study was to assess the impact of two-jaw orthognathic surgery on the 3D airway volume in patients with skeletal Class III patterns. The study included 27 adult patients with dental Class III malocclusion and mandibular prognathism who underwent two-jaw orthognathic surgery. The changes in airway volume were evaluated using computed tomography simulation and segmentation was carried out using 3D Slicer. Results showed that the average upper airway volume increased by 1979.1 mm3, the oropharyngeal airway volume increased by 336.4 mm3, and the hypopharyngeal airway volume decreased by 1087.5 mm3. Despite this decrease, the overall airway volume still increased by an average of 1228.1 mm3. The findings suggest that two-jaw orthognathic surgery has a positive impact on the overall airway volume in patients with skeletal Class III patterns.
