To evaluate the anatomical variations in computed tomographic (CT) images of paranasal sinuses and to investigate association between them.
Retrospective study.
Tertiary care center in the southern part of India.
Radiological images of paranasal sinuses belonging to chronic rhinosinusitis patients managed between June 2016 and November 2018.
The studied characteristics in the CT images included the deviated nasal septum (DNS), concha bullosa (CB), Haller cell (HC), Onodi cell (OC), pneumatization of anterior clinoid process (ACP), pterygoid base (PB), superior turbinate, inferior turbinate, crista galli (CG), and nasal septum. The height of the lateral lamella of the cribriform plate, the sphenoid pneumatization pattern, and the optic nerve relationship with sphenoid sinus were studied separately. The associations between these factors, and with maxillary sinus opacifications were also investigated. A total of 151 adult patients' CT images were analyzed. The most common manifestations noted were DNS, CB and pneumatized PB, seen in 83.4%, 49% and 47% of the patients respectively. The rates of HC, OC, pneumatized septum, pneumatized CG, and pneumatized ACP were 39%, 23%, 27%, 43% and 27% in that order. Rates of most of these variations were within the range reported in the literature. Chi square test revealed that the OC was independently associated with pneumatized CG and pneumatized septum. The maxillary sinus opacification was related to DNS and CB, but not with protrusion of tooth root into the sinus. Most of the anatomical variations were comparable with the reports across the globe, however, the associations between these variations weren't common in our cohort.
评估鼻窦计算机断层扫描（CT）图像中的解剖变异，并研究它们之间的关联。
回顾性研究。
印度南部的三级医疗中心。
2016年6月至2018年11月期间接受治疗的慢性鼻窦炎患者的鼻窦放射影像。
CT图像中研究的特征包括鼻中隔偏曲（DNS）、泡状鼻甲（CB）、哈勒氏气房（HC）、蝶筛隐窝气房（OC）、前床突气化（ACP）、翼突基部气化（PB）、上鼻甲、下鼻甲、鸡冠（CG）和鼻中隔。分别研究筛板外侧板的高度、蝶窦气化模式以及视神经与蝶窦的关系。还研究了这些因素之间以及与上颌窦混浊之间的关联。共分析了151例成年患者的CT图像。最常见的表现为DNS、CB和气化的PB，分别见于83.4%、49%和47%的患者。HC、OC、气化鼻中隔、气化CG和气化ACP的发生率依次为39%、23%、27%、43%和27%。这些变异中大多数的发生率在文献报道的范围内。卡方检验显示，OC与气化CG和气化鼻中隔独立相关。上颌窦混浊与DNS和CB有关，但与牙根突入鼻窦无关。大多数解剖变异与全球报告相当，然而，这些变异之间的关联在我们的队列中并不常见。
