“…Anatomically, it is the most anterior ethmoid cell pneumatizing laterally into the lacrimal bone. Our data indicate that the prevalence of the agger nasi cell may be as high as 93.9%, in line with studies conducted by other investigators [14][15][16]20] (from 86.7% [15] to nearly 100% [20] ). By using the agger nasi cell as an anatomical landmark (the agger nasi cell approach) [18] , the endoscopic frontal recess operation starts with opening of the anteroinferior wall of the agger nasi cell followed by removal of the medial, roof and posterior walls of the agger nasi cell.…”

“…2 a, c), the frontal recess could be reached anteriorly or inferiorly without obstructing cells above it by using different approaches [18,22] . Although Lee et al [14] reported that the prevalence of frontal cells was as high as 64%, 3 others found lower rates (25.5% [15] , 20.4% [13] and 44.7% in Koreans [16] ); our findings (39.6%) are generally in line with the latter 3 reports. Complex situations arose when the frontal cells had anterior blockages in the frontal sinus drainage pathway.…”

The purposes of this study were to determine the prevalence of frontal-ethmoidal cells and to evaluate variation in the superior attachment of the uncinate process in Chinese subjects. 202 normal Chinese subjects (404 sides) underwent spiral computed tomography and multiplanar reconstruction images were evaluated. Agger nasi cells showed a prevalence of 94.1%. Of all the frontal cells identified in 159 sides (39.6%) of frontal recesses, the prevalence of type I, type II and type III cells was 24.4, 7.0 and 8.2%, respectively. Suprabullar, frontal bullar and interfrontal septal cells were identified in 148 sides (36.6%), 36 sides (9.0%) and 25 subjects (12.4%), respectively. 244 uncinate processes (60.4%) had 1 superior attachment and the remainder (39.6%) had 2 superior attachments. The prevalence of terminal recesses was 89.1%. Our results characterized normal frontal recess pneumatization patterns in Chinese subjects. That, together with variation in the superior attachment of the uncinate process, emphasized the role of agger nasi cells and the uncinate process in endoscopic frontal sinus surgery.

“…Bent III et al 10 in their study correlated the presence of frontal cells in CT scan and intraoperatively -they found the incidence of type III or IV frontal cells to be between 1 and 2%. Cho et al 11 found frontal cell type I in 22.8%, type II in 14%, type III in 7.9%, and type IV in 0% in CT scan. The CT showed positive correlation with intraoperative findings (coefficient of correlation 0.88) in identification of frontal bullar cells.…”

To compare the anatomical and pathological features on computed tomography (CT) scan with intraoperative findings in cases of frontal sinus disease. This prospective study was conducted in a tertiary referral center, and a total of 30 patients who were refractory to conservative medical treatment undergoing endoscopic sinus surgery for frontal sinus disease were included in the study. Preoperative CT scans were done with axial and coronal cuts with a sagittal reconstruction to obtain a better idea about the frontal recess anatomy. The areas that were studied preoperatively on CT scan were frontal sinus pathology, pattern of sinus involvement, superior attachment of uncinate process, frontal sinus drainage pathway, agger nasi cell, frontal cell, frontal bullar cell, and supraorbital ethmoidal cell. A good correlation was obtained between the CT findings and intraoperative findings.

“…These cells drain into the one of the FR and are well defined in the coronal and axial scans [57]. The incidence rate in the literature is reported as 12.4 [56] and 14% [58].…”

“…On coronal images, the presence of bony septum between the ethmoid complex and the recess separates the frontal sinus from the SOEC [18]. These cells drain into the lateral aspect of the FR [57]. Because of the close relation between the SOEC and anterior ethmoidal artery, enlarging the SOEC could risk damage to the artery [59].…”

CBCT Imaging of Paranasal Sinuses and Variations

Paranasal Sinuses

View full text Add to dashboard Cite

Paranasal sinuses located in the bones surrounding the nasal cavity are called maxillary, ethmoid, frontal and sphenoid sinuses. In relation with their location, these sinuses contribute to the development of the facial structures, jaws and upper airway. During the developmental process of the paranasal sinuses, anatomic variations can occur in consequence of intra and extramural migration of the ethmoid air cells, overpneumatization or hypoplasia of the sinuses and bulging of the neurovascular structures to the sinuses. Some of these anatomic variations may affect the drainage pathways, pave the way for chronic infections and cause difficulties when performing paranasal sinuses surgery.Therefore, the aim of this chapter was to examine the paranasal sinus anatomic variations with cone beam computed tomography (CBCT).
