Nasal breathing is the major pattern of air intake. Changes in breathing pattern alter the posture of the head, jaws and tongue that could change pressure on the jaw and teeth and affect their growth.
This study aimed to investigate the relationship between septal deviations (SD) per se and in combination with concha bullosa (CB) on maxilla; particularly the depth of palatal arch.
This descriptive-comparative study was performed on 116 cone-beam computed tomography (CBCT) images. The images were categorized into four groups (n=29) as follows; group 1: SD+CB, group 2: only SD, group 3: neither SD nor CB, and group 4: only CB. In coronal images, deviated septal length (DSL), angle of deviated septal curve (DSCA), palatal arch depth (PAD), palatal interalveolar length (PIL), PAD/PIL ratio, septal vertical length (SVL), maxillopalatal arch angle (MPAA), interjugum distance (IJD), and jugum angle (JA) were measured. The data were statistically analyzed with Tukey's HSD and Chi-square tests.
There were statistically significant differences in DSL and DSCA (p= 0.0001) among the four groups. The study groups were not statistically different regarding the IJD, JA, MPAA, PAD/PIL, PAD, PIL, and SVL. However, in group 1, PAD/PIL were significantly correlated with DSCA and DSL (p= 0.037, and p= 0.043, respectively).
Based on the findings of this study, simultaneous occurrence of SD and CB influenced the depth and curve of the palatal bone. The PAD/PIL ratio was negatively correlated with the DSCA angle. This correlation was associated with a decrease in PAD, indicating that concurrent occurrence of SD and CB remarkably affected the palatal base of maxilla.
鼻腔呼吸是主要的空气吸入方式。呼吸模式的改变会改变头部、颌骨和舌头的姿势，进而可能改变颌骨和牙齿上的压力并影响其生长。
本研究旨在调查鼻中隔偏曲（SD）本身以及与泡状鼻甲（CB）合并存在时与上颌骨的关系；特别是腭弓深度。
本描述性比较研究对116张锥束计算机断层扫描（CBCT）图像进行。图像被分为四组（每组n = 29）如下：第1组：SD + CB；第2组：仅SD；第3组：既无SD也无CB；第4组：仅CB。在冠状位图像上，测量偏曲鼻中隔长度（DSL）、偏曲鼻中隔曲线角度（DSCA）、腭弓深度（PAD）、腭牙槽间长度（PIL）、PAD/PIL比值、鼻中隔垂直长度（SVL）、上颌腭弓角度（MPAA）、颧颌间距（IJD）和颧颌角（JA）。数据采用Tukey's HSD检验和卡方检验进行统计学分析。
四组之间DSL和DSCA存在统计学显著差异（p = 0.0001）。研究组在IJD、JA、MPAA、PAD/PIL、PAD、PIL和SVL方面无统计学差异。然而，在第1组中，PAD/PIL与DSCA和DSL显著相关（分别为p = 0.037和p = 0.043）。
基于本研究结果，SD和CB同时存在会影响腭骨的深度和曲线。PAD/PIL比值与DSCA角度呈负相关。这种相关性与PAD的降低有关，表明SD和CB同时存在显著影响上颌骨的腭基部。
