“…9 Onodi cells have been more recently divided into different types according to their pneumatization depth toward the SS and their relation to the optic nerve canal. 8,10,11 In addition, the anatomical definition of Onodi cell has been more clearly defined. The Onodi cell is limited to the most PE cell, which extends posteriorly to lie superolateral to the SS and, thus, in close proximity to the optic nerve and the internal carotid artery.…”

Background: The sphenoethmoidal cell and the sphenoid sinus (SS) show great similarity in endoscopy and imaging. Hence, it is important to accurately identify the sphenoethmoidal cell preoperatively to prevent injury of the nerve and artery during endoscopic surgery. The aim of the present study was to investigate a special type of sphenoethmoidal cell. Methods: A total of 365 inpatients whose paranasal sinus computed tomography (CT) was collected and reviewed from May 2018 to September 2019 were included. The anatomical imaging characteristics of the sphenoethmoidal cell were observed. Results: A special type of the sphenoethmoidal cell was found on 9 sides in 730 sides (1.3%), according to its extension to the SS. Unlike Onodi cell (49.6%) and Jinfeng cell (1.3%), this cell simultaneously extends toward the superolateral, lateral, and inferolateral regions of the SS and is simultaneously closely attached to the optic canal and the maxillary nerve. Presently, this cell is named as the whole lateral type of the sphenoethmoidal cell, and the SS is located at the medial or inferomedial of it. Conclusions: When evaluating the paranasal sinus CT preoperatively, attention must be paid to the possibility of the whole lateral type of sphenoethmoidal cell appearing, not just Onodi cell, extending into the SS.

Background Anatomical analysis of the sphenoid sinus is important because of its proximity to vital neurovascular structures. The aim of this study is investigating the anatomy of the SS and its surrounding structures in CBCT images. Methodology: In this retrospective cross-sectional study, 201 cone-beam computed tomography (CBCT) radiographs were analyzed. The analyzed images included the type of SS, protrusion of ICA and optic nerve and foramen rotundum, vidian canal type, the Onodi cell, pneumatization to surrounding bones, the ostium, the septum. The data were analyzed using chi-square and the t-test in SPSS 24 at a significance level of 0.05. Results The tilted septum had the highest frequency (46.3%). Ostium was bilateral in most images (56.2%). The protrusion of the ICA (54.7%) and optic nerve (62.2%) was smooth in most images. Foramen rotundum protrusion and Onodi cell prevalence were 25% and 22.9%, respectively. The postsellar type of sinus had the highest frequency (71.1%). Vidian canal Grade II had the highest frequency (40.3%). Greater wing pneumatization had the highest frequency (51.7%). No statistically significant relationship was found between the optic nerve protrusion and Onodi cell (P-value < 0.05). There was a significant relationship between the pneumatization of the pterygoid process and the protrusion of the vidian canal, and the foramen rotundum protrusion (p-value < 0.001). Conclusion CBCT imaging is very effective in the anatomical analysis of the SS and its surrounding structures. The postsellar type had the highest frequency.Vidian canal Grade II had the highest frequency; greater wing pneumatization was observed in more than half of the images; the most common type of septum was tilted; ostium was bilateral in most cases; the protrusion of the ICA and optic nerve was mostly smooth.
