Background. The frontal recess area represents a challenge to ENT surgeons due to its narrow confines and variable anatomy. Several types of cells have been described in this area. The agger nasi cells are the most constant ones. The frontal cells, originally classified by Kuhn into 4 types, have been reported in the literature to exist in 20%-41% of frontal recesses. Aim of the Study. To identify the prevalence of frontal recess cells and their relation to frontal sinus disease. Methods. Coronal and axial CT scans of paranasal sinuses of 70 patients admitted for functional endoscopic sinus surgery (FESS) were reviewed to identify the agger nasi, frontal cells, and frontal sinus disease. Data was collated for right and left sides separately. Results. Of the 140 sides reviewed, 126 (90%) had agger nasi and 110 (78.571%) had frontal cells. 37 frontal sinuses were free of mucosal disease, 48 were partly opacified, and 50 were totally opacified. There was no significant difference found in frontal sinus mucosal disease in presence or absence of frontal cells or agger nasi. Conclusions. The current study shows that frontal cells might be underreported in the literature, as the prevalence identified is noticeably higher than previous studies.
背景。额隐窝区域因其狭窄的范围和多变的解剖结构，给耳鼻喉科医生带来了挑战。该区域已被描述有几种类型的细胞。鼻丘气房是最恒定存在的。额气房最初由库恩分为4种类型，文献报道其在额隐窝中的存在率为20% - 41%。研究目的。确定额隐窝细胞的患病率及其与额窦疾病的关系。方法。回顾了70例因功能性鼻内镜鼻窦手术（FESS）入院患者的鼻窦冠状位和轴位CT扫描图像，以确定鼻丘气房、额气房和额窦疾病。数据分别按左右侧进行整理。结果。在140侧被检查的鼻窦中，126侧（90%）有鼻丘气房，110侧（78.571%）有额气房。37个额窦无黏膜病变，48个部分浑浊，50个完全浑浊。有无额气房或鼻丘气房的情况下，额窦黏膜疾病无显著差异。结论。当前研究表明，额气房在文献中的报道可能不足，因为本研究确定的患病率明显高于先前的研究。
