Abstract：
Background: The pneumatization of the frontal sinus is variable between individuals, including monozygotic twins. The volumetric anatomic variants of the frontal sinus are classified into aplasia, hypoplasia, medium-sized, and hyperplasia. We aimed to study the frontal sinus morphology in Omani patients using computed tomography (CT) evaluations. Methods: Retrospectively, 1220 frontal sinus CT scans from 610 patients investigated at Sultan Qaboos University Hospital, Oman, from January 2019 to December 2020 were reviewed. The frontal sinus morphology was classified according to the classification proposed by Guerram et al. The Chi-square test was used to determine the influence of sex. Results: With regard to the unilateral occurrence, the most prevalent frontal sinus category observed was medium-sized (13.3%), followed by hyperplasia (7.9%), hypoplasia (5.4%), and aplasia (2%) categories. Similarly, in bilateral occurrence, the most common frontal sinus category observed was medium-sized (53%), followed by hyperplasia (13.1%), hypoplasia (3.4%) and aplasia (2%) categories. Right and left frontal sinus aplasia were observed in 2.1% and 1.8% of cases, respectively. In terms of sex influence, the left unilateral ( p<0.01) and the bilateral hypoplasia ( p<0.05) were significantly higher in females. On the other hand, the left unilateral ( p<0.01) and the bilateral hyperplasia ( p<0.05) were higher in males. Conclusions: The baseline data of frontal sinus category frequencies reported in the present study is helpful in the diagnostic evaluation of sinusitis in the clinical setting. The preoperative recognition of frontal sinus types, particularly frontal sinus aplasia in multiplanar CT scans, is crucial to avoid unexpected complications while performing endoscopic sinus surgery.
摘要：
背景：额窦的气化在个体之间是可变的，包括单卵双胞胎.额窦的体积解剖变异分为发育不全，发育不全,中型,和增生。我们旨在使用计算机断层扫描（CT）评估来研究阿曼患者的额窦形态。方法:回顾性,在苏丹卡布斯大学医院调查的610名患者的1220个额窦CT扫描，阿曼,从2019年1月到2020年12月进行了审查。额窦形态根据Guerram等人提出的分类进行分类。用卡方检验确定性别的影响。结果：关于单侧发生，观察到的最普遍的额窦类别是中型（13.3％），其次是增生(7.9%),发育不全(5.4%),和再生障碍(2%)类别。同样，在双侧发生时，观察到的最常见额窦类别是中型（53％），其次是增生(13.1%)，发育不全（3.4％）和发育不全（2％）类别。在2.1%和1.8%的病例中观察到右和左额窦发育不全,分别。就性别影响而言，女性左侧单侧（p<0.01）和双侧发育不全（p<0.05）明显高于女性。另一方面,男性左侧（p<0.01）和双侧增生（p<0.05）较高。结论：本研究报告的额窦类别频率的基线数据有助于在临床上对鼻窦炎的诊断评估。术前识别额窦类型,尤其是多平面CT扫描中额窦发育不全,是至关重要的，以避免意外的并发症，同时进行内窥镜鼻窦手术。
