To analyze the pneumatization pattern of the frontal recess using CT scans and to determine the prevalence of frontoethmoidal cells and their possible correlation with the development of sinusopathy.
By means of a retrospective, analytical and cross-sectional study, 300 CT scans of patients with clinical suspicion of chronic rhinosinusitis were examined, separately on the right and left sides, totaling a sample of 600 paranasal sinuses, with regard to the presence of frontal cells, the presence of blockage or veiling of the recess and frontal sinus.
Frontoethmoidal cells were present in 85.8% of cases; the most frequent cells were supra bulla cells, in 43.8%, and the least frequent were supraorbital ethmoid cells, in 11% of cases. There was a 35% prevalence of supra-Agger cells, 15.8% of supra-Agger frontal cells, 20.2% of supra bulla frontal cells and 12.3% of frontal septal cells. A significant relationship was found between the presence of supra-Agger frontal cells and supra bulla frontal cells and the development of sinusopathy.
The supra-Agger frontal cells and supra bulla frontal cells, when present in the frontal recess, predispose to the development of frontal sinusopathy. Therefore, preoperative tomographic analysis allows a three-dimensional anatomical understanding of the recess and frontal sinus based on determining the pneumatization pattern of this region.

通过CT扫描分析额隐窝的气化模式，确定筛窦气房的患病率及其与鼻窦疾病发生的可能相关性。
采用回顾性、分析性横断面研究，对300例临床怀疑患有慢性鼻窦炎患者的CT扫描进行检查，分别对左右两侧进行分析，共计600个鼻窦样本，观察额气房的存在情况、隐窝和额窦的阻塞或遮盖情况。
85.8%的病例存在筛窦气房；最常见的气房是泡上气房，占43.8%，最不常见的是眶上气房，占11%。上筛泡气房患病率为35%，上筛泡额气房为15.8%，泡上额气房为20.2%，额中隔气房为12.3%。发现上筛泡额气房和泡上额气房的存在与鼻窦疾病的发生之间存在显著关系。
额隐窝中存在上筛泡额气房和泡上额气房时，易引发额窦疾病。因此，术前断层扫描分析可基于该区域的气化模式，对隐窝和额窦进行三维解剖学理解。
