Chronic rhinosinusitis (CRS) is a syndrome with multifactorial aetiology. Amongst which, anatomical variations studied by computed tomography of paranasal sinuses (CT PNS) had a high incidence which varied between 64.0% and 99.8%. Due to such high incidence, this study is undertaken to assess the various anatomical variations and their significant association in CRS.
A prospective observational study was conducted in 70 CRS patients and were subjected to CT PNS. CT PNS is studied to know the various anatomical variations & other CT findings causing CRS and then findings noted down, tabulated and statistical analysis done.
All 70 CRS patients evaluated by CT PNS had one or more anatomical variations along with other findings like fungal sinusitis in 6 patients, dentigerous cyst and inverted papilloma in 1 case each. The anatomical variations observed in our study were septal deviation(62.8%), concha bullosa(52.8%), agger nasi(51.4%), pneumatized crista galli(47.1%), hyperpneumatized bulla(40%), suprabullar cells(37%), septal spur(34.3%), paradoxically curved middle turbinate(34.2%), supra orbital cells(32.8%), haller cells(31.4%), septal pneumatization(17.1%), pneumatized uncinate(13%), interfrontal septal pneumatization(13%), maxillary septations(10%), maxillary sinus hypoplasia(7.1%), frontal hypoplasia(5.7%), uncinate attached to lamina papyracea(40%), uncinate to middle turbinate(11%), uncinate to skull base(7.9%), free uncinate(41%), frontal cells type 1;2;3;4 (36%);(30%);(20%);(38.5%), onodi cells(27.1%), pneumatized anterior clinoid process(18.5%), lateral recess(15.7%), sphenoid septations attached to optic nerve(10%) and carotid(2.8%), pneumatized superior turbinate(1.4%), Sellar; Pre sellar; Post sellar sphenoid(42.8%);(5.7%);(51.4%). In our study only anatomical variations around the maxillary & Frontal sinus showed significant association with CRS.
Anatomical variations around the anterior group of sinuses have a significant association with CRS.
慢性鼻 - 鼻窦炎（CRS）是一种病因多因素的综合征。其中，经鼻窦计算机断层扫描（CT PNS）研究的解剖变异发生率很高，在64.0%至99.8%之间。由于如此高的发生率，本研究旨在评估CRS中各种解剖变异及其显著关联。
对70例CRS患者进行前瞻性观察研究，并对其进行CT PNS检查。通过研究CT PNS来了解导致CRS的各种解剖变异及其他CT表现，然后记录结果、列表并进行统计分析。
所有70例经CT PNS评估的CRS患者都有一个或多个解剖变异，以及其他表现，如6例患者有真菌性鼻窦炎，1例患者有含牙囊肿和内翻性乳头状瘤。在我们的研究中观察到的解剖变异有鼻中隔偏曲（62.8%）、泡状鼻甲（52.8%）、鼻丘气房（51.4%）、气化鸡冠（47.1%）、过度气化的筛泡（40%）、筛泡上细胞（37%）、鼻中隔棘突（34.3%）、反常弯曲的中鼻甲（34.2%）、眶上气房（3
