Abstract

Introduction

Nasal septal deviation (NSD) is a common anatomical variation influencing nasal function and maxillary development. This study aims to evaluate the correlation between NSD and maxillary dimensions in a South Indian population using cone-beam computed tomography (CBCT). Additionally, it examines NSD severity and its effect on maxillary dimensions and malocclusion.

Methods

The retrospective cross-sectional study analysed CBCT data from patients with NSD aged above 18 years and of South Indian descent, collected between 2022 and 2024, who satisfied the inclusion and exclusion criteria. NSD severity was classified based on the Septal Deviation Angle (SDA) as mild (0–9°), moderate (10–15°), and severe (> 15°). Maxillary parameters such as: palatal width (MPW), length (ML), palatal arch depth (PAD), intermolar width (MIMW), interpremolar width (MPMW) were measured. The association between NSD and maxillary parameters was analysed using the Pearson correlation coefficient. The analysis of variance (ANOVA) was employed to examine the transverse maxillary parameters among three groups with different severity levels.

Results

A total of 140 CBCTs scans were analysed based on the inclusion and exclusion criteria. A weak positive correlation was observed between SDA and PAD (P = 0.038), DSW-PAD (P = 0.040) and DSW-MPW (P = 0.030). MPW was significantly reduced in moderate NSD patients compared to mild NSD (P = 0.048). Class II malocclusion was most prevalent across all NSD severities (mild: 20%, moderate: 25%, severe: 15%).

Conclusion

The nasal septal deviation is associated with increased palatal depth and reduced palatal width, particularly in moderate NSD cases.

南印度成年人鼻中隔偏曲与上颌尺寸的关系：一项回顾性观察锥束计算机断层扫描研究

导言：鼻中隔偏曲（NSD）是影响鼻功能和上颌骨发育的常见解剖变异。本研究旨在使用锥形束计算机断层扫描（CBCT）评估南印度人群中鼻中隔偏曲与上颌骨尺寸之间的相关性。这项回顾性横断面研究分析了 2022 年至 2024 年期间收集的符合纳入和排除标准的 18 岁以上南印度裔 NSD 患者的 CBCT 数据。根据鼻中隔偏离角（SDA）将 NSD 严重程度分为轻度（0-9°）、中度（10-15°）和重度（15°）。测量的上颌参数包括：腭宽（MPW）、腭长（ML）、腭弓深度（PAD）、磨牙间宽（MIMW）、磨牙间宽（MPMW）。使用皮尔逊相关系数分析了 NSD 与上颌参数之间的关系。结果根据纳入和排除标准，共分析了 140 张 CBCT 扫描图像。SDA与PAD（P = 0.038）、DSW-PAD（P = 0.040）和DSW-MPW（P = 0.030）之间呈弱正相关。与轻度 NSD 相比，中度 NSD 患者的 MPW 明显降低（P = 0.048）。结论鼻中隔偏曲与腭深增加和腭宽减少有关，尤其是在中度 NSD 患者中。
