The nasal septum is a crucial supporting factor for the nasal cavity and may develop several anatomical variants including septal deviation, spur and pneumatization. These variants could be associated with a higher incidence of sinusitis due to structural and functional alterations. So, the aim of this study was to assess the prevalence of nasal septal deviation (NSD), nasal septal spur (NSS) and nasal septal pneumatization (NSP) among the Saudi adult population and their links with the incidence of sinusitis by using computed tomography (CT). A retrospective study was achieved over a twenty-two months period on 681 adult Saudi subjects (420 males and 261 females) aged 20 years or older, referred for coronal CT evaluation of the paranasal sinuses. NSD and NSS were significantly more prevalent in males than females (80.0% vs. 67.4% respectively for NSD, and 34.5% vs. 24.9% respectively for NSS), while there was no statistical difference in frequency of NSP regarding gender (=0.670). The incidence of sinusitis was significantly higher in presence of NSD and/or NSS (<0.001 for both). On the contrary, NSP was not associated with a significant increase in the prevalence of sinusitis (=0.131). In conclusion, NSD and NSS are more prevalent in males than females among the Saudi population with no statistical difference between both genders regarding the presence of septal pneumatization. Furthermore, sinusitis is more prevalent with the occurrence of NSD and NSS, and not related to the incidence of NSP.
鼻中隔是鼻腔的一个关键支撑结构，可能会出现多种解剖变异，包括鼻中隔偏曲、棘突和气化。由于结构和功能的改变，这些变异可能与鼻窦炎的发病率较高有关。因此，本研究的目的是通过计算机断层扫描（CT）评估沙特成年人群中鼻中隔偏曲（NSD）、鼻中隔棘突（NSS）和鼻中隔气化（NSP）的患病率及其与鼻窦炎发病率的关系。在22个月的时间里，对681名年龄在20岁及以上的沙特成年受试者（420名男性和261名女性）进行了一项回顾性研究，这些受试者因鼻窦冠状位CT评估而被转诊。NSD和NSS在男性中的患病率显著高于女性（NSD分别为80.0%和67.4%，NSS分别为34.5%和24.9%），而NSP的发生率在性别方面没有统计学差异（P = 0.670）。在存在NSD和/或NSS的情况下，鼻窦炎的发病率显著更高（两者均P < 0.001）。相反，NSP与鼻窦炎患病率的显著增加无关（P = 0.131）。总之，在沙特人群中，NSD和NSS在男性中比女性更普遍，在鼻中隔气化的存在方面，两性之间没有统计学差异。此外，鼻窦炎在NSD和NSS发生时更普遍，与NSP的发生率无关。
