“…When comparing median total EC count in CRSwNP patients compared to CRSsNP patients, no significant difference was observed for both, sagittal EC count (16. 5 No significant correlation between Lund-Mackay-Score and axial, or sagittal cell count, or the product of it was observed (sagittal r = 0.051, P = .723; axial r = −0.018, P = .901; product r 2 = 0.030, P = .838).…”

Objectives/Hypothesis: Studies analyzing the association between the total number of ethmoid cells (EC) and chronic rhinosinusitis (CRS) are missing. Our aim was to analyze the total number of EC in patients with and without CRS.Study Design: Retrospective case-control study.Methods: A total of 50 computed tomography (CT) scans of patients with CRS, 14 CT scans of patients with odontogenic CRS, and 50 CT scans of healthy controls were retrospectively analyzed. The number of EC has been determined for each side separately.Results: In total 228 sides have been analyzed. The bilateral total EC count in both planes was more than 2 cells higher, when comparing CRS patients to healthy controls or odontogenic CRS patients (P < .01). No difference was observed, when comparing healthy and odontogenic CRS patients. Conclusion:The number of EC on CT of CRS patients is significantly higher than in both, the healthy and the odontogenic CRS control group. Cell count could contribute to the pathogenesis of CRS.

“…In terms of the medial group, Wang et al [2] have studied the anatomy of the intersinus spetal cell (ISSC, i.e., FSC) and its impact on endoscopic surgery. For the posterior group, a few studies addressed the anatomy of the SOEC [13, 14] and studies on SBFCs have mainly focused on its clinical significance [4, 5] However, a detailed comparison of the anatomical structure and clinical significance of the SBFC and SOEC has not been reported to date.…”

“…It is associated with many factors such as microbial dysbiosis, genetic factors, anatomical variations, and allergy [1]. Anatomical variations, particularly the complex frontal recess, are a known risk factor of CRS and have been a major research topic [2][3][4][5] (IFAC) published in 2016 [6] emphasized not only the location and number of the cells but also the influence of the cells on the frontal sinus drainage pathway. This system provides surgeons with an accurate nomenclature for cells based on their positions and helps surgeons have a better understanding of the frontal sinus.…”

Introduction: The anterosuperior portion of the bulla lamella can extend into the frontal sinus and form the supra bulla frontal cell (SBFC) and supraorbital ethmoid cell (SOEC). This can affect the frontal drainage pathway and make surgery more challenging. Objectives: The aim of the study was to compare the anatomical characteristics of SBFC and SOEC in Chinese chronic rhinosinusitis (CRS) patients and explore the relationship between the cells and frontal sinusitis (FS). The surgical skills in dealing with these cells were also studied. Methods: We prospectively identified SBFC and SOEC in 114 patients with CRS by computed tomography (CT). The sides of the patients were divided into groups A (with FS) and B (without FS). CT scans were analyzed to distinguish the SBFC, SOEC, and the drainage pathway. Statistical analysis was conducted to determine whether the cells were associated with the occurrence of FS. Results: The prevalence of frontal cells was as follows: SBFC: 9.65%, SOEC: 21.93%. There was an association between the presence of SBFC and FS (p < 0.05). The anterior drainage pathway was present in patients with SBFC and SOEC, anterolateral pathway in those with SBFC/SOEC coexisting with the frontal septal cell, and anteromedial pathway in those with SBFC/SOEC coexisting with the supra agger frontal cell. Conclusions: There was an association between the presence of SBFC and the occurrence of FS. Extension of the anterosuperior portion of the bulla lamella into the frontal sinus obstructed the drainage pathway posteriorly. Understanding the anatomy may help surgeons thoroughly dissect the bulla lamella.

“…This can be correlated with the results of the present study as a significant association was observed between left-sided maxillary sinusitis and ethmoid sinusitis and RH with a p-value of 0.03, and 0.05 respectively. Research shows that very few studies are done related to this topic in which both the sinus-mucosal infection and anatomical variants of the sinonasal region are correlated with RH [16][17][18][19] . Some authors have investigated the prevalence of frontal cells and only a few studies are done in which the association of these cells with RH was observed [20][21][22] .…”

Background: Variable anatomy, hallmark of sinonasal region is the reason for the etiology of sinonasal symptoms such as rhinogenic headache. This study aimed to investigate the incidence of anatomical variations of the nasal cavity and paranasal sinuses in sinusitis patients with complaint of rhinogenic headache on computed tomography of paranasal sinuses, and the correlation of these variants with a rhinogenic headache. Methods:A prospective cross-sectional study (n=50) of 18-60 years having sinusitis with rhinogenic headache was steered at the Department of Radiology in the PNS Shifa Hospital of Karachi, Pakistan, between June-December 2021. After obtaining written informed consent, all subjects were investigated for various anatomical variants of the sinonasal region detected on computed tomographic scans of paranasal sinuses and were correlated with a rhinogenic headache. The Chi-square test and Pearson correlation were applied for statistical analysis and the level of significance was set at p≤ 0.05. Results:The most common anatomical variant of sinonasal region detected was agger nasi cells 32(64%) (Right: ρ/r -0.24, p =0.09; Left: ρ/r -0.28, p = 0.04), followed by deviated nasal septum 28(56%) (ρ/r 0.04, p= 0.75), concha bullosa 23(46%) (ρ/r 0.07, p=0.59), deviated nasal septum with bony spur (ρ/r 0.07, p=0.62) and other variants. The overall, study found male (68%) predominance. Significant association existed between rhinogenic headache and some of the anatomical variants along with sinus mucosal thickening (p<0.05). Conclusion:The significant association (p<0.05) was found between rhinogenic headache and different anatomical variants like agger nasi cells, left-sided agger nasi cells, right-sided Haller's cells, left-sided maxillary and ethmoid sinusitis.
