“…Furthermore, there are also significant differences among different types of the sphenoethmoidal cells. Liu et al 4 have detailed the difference between ISEC and Onodi cell (Table 1). In addition, the simultaneous extension of PEs toward the superolateral and inferolateral regions of the SS on the same side forms the Onodi cell and the ISEC, respectively, which may be related to the number of most PE cells (Figure 3D).…”

“…4 Furthermore, when the 2 most PE cells expand into the SS on the same side, the Onodi cell and ISEC, respectively, are formed by extending toward the superolateral and inferolateral regions of the SS. 4 Therefore, the sphenoethmoidal cell contains not only the Onodi cell but also the ISEC. To further elucidate the anatomical variation in sphenoethmoidal cells, we investigated the extension of the PE toward the SS.…”

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.

“…In patients with chronic nasal obstruction, because the nasal structure varies greatly among different individuals, 25 , 26 it is necessary to individually evaluate the abnormal nasal structure according to different patients. When a patient has many structural abnormities at the same time, how can the structure of surgical intervention be chosen?…”

Septoplasty is widely used in the treatment of structural nasal obstructions, and it also has a good effect and a high degree of postoperative satisfaction. However, there a large number of structures demonstrate abnormalities related to structural nasal obstruction, including the external nose, maxilla, nasal cavity and paranasal sinus. Nasal septum deviation is only one signs of structural nasal obstruction and does not represent all possible structural abnormalities of the nasal cavity and its surrounding structure. Septoplasty is only performed to correct deviations of the nasal septum, which in many cases is obviously insufficient in restoring the symmetry of the nasal structure. Therefore, septoplasty alone is not suitable for the treatment of most structural nasal obstructions. Nasal ventilation expansion surgery, which typically covers more abnormal structural correction procedures than septoplasty, should be used when describing the treatment of structural nasal obstruction.

“…1 The ethmoid sinus includes the infraorbital ethmoid, Haller, ethmoid maxillary sinus, retromaxillary posterior ethmoid cell, and Onodi cell. 2 However, there have been no reports on a single cell that is pneumatized in the supraethmoidal and supraorbital regions and extends to the anterior wall of the sphenoid sinus. We present a patient with this unique sinus anatomical variation found on preoperative computed tomography (CT) and confirmed this finding in the operation.…”
