“…At this time, line 6 is very important because the surgeon must completely remove the bottom part of the lesion, line 3, and the horizontal distance from the sphenoid ostium to the posterior wall of sphenoid sinus. If sphenoid sinus ostium is located superior to the level of the lowest point of sella, the surgeon must be very careful [10][11][12] because the instruments are advanced into the sinus. Once the sphenoidal sinus is entered into, the anatomic structures of the sphenoidal sinus posterior wall will be the unique landmarks that can guide the surgeon to the surgical target [13] too deep to explore and also that can possibly hurt the pituitary.…”

The objective this study was to measure the changes of sphenoid sinusin the Chinese in AsiausingCT sagittal thin-slice reconstruction images, and to clarify the three-dimensional anatomical features of sphenoid sinus with its surrounding structures, relevant to the performing of the endoscopic sphenoidotomy. The sagittal reconstruction images were obtained from 178 CT images of 89 cases of normal adult participants (54 males and 35 females) with sphenoid sinus. We took the high-resolution axial CT images, from all the subjects, of the thickness by 0.625 mm, and reconstructed 1-mm-thick gapless sagittal CT images to measure the distance of all the sellar and pre-sellar types on the three-dimensional reconstructable sagittal plane under the bone window (4,000 at its width, and 400 at its level) in the CT images. The length of mean vertical line from the center of sphenoid ostium to the roof of sphenoid sinus of Non Onodi cell type is 10.6 ± 1.5 mm, and of Onodi cell type is 3.3 ± 1.5 mm. The length of vertical line from the center of sphenoid ostium to the lowest level of the bottom of sphenoid sinus is 12 mm ± 3.7 mm. The length of mean horizontal line from the sphenoid ostium to the posterior wall of sphenoid sinus is 18 ± 1.5 mm or 28 ± 2.5 mm. The mean horizontal line from the lowest point of the sella to the anterior wall of sphenoid sinus is 17.5 ± 1.3 mm in length. The mean horizontal distance from anterior wall to posterior wall of sphenoid sinus of Non Onodi cell type lining skull base is 10.1 ± 1.0 mm, and of Onodi cell type, is 5.2 ± 4.3 mm. The longest horizontal distance from the anterior wall to the posterior wall of sphenoid sinus is 22.0 ± 7.7 mm. The present study provides atomical information about sphenoid sinus of the Chinese in Asia with some surgical distance measured between the sphenoid ostium and the surrounding structures, which is essential to avoid the complications during surgery.

“…However, operations related to the sphenoid sinus have become considerably easier, because of the improvements in optical aids such as endoscopes and operating microscopes. 1 Location of the natural ostium of the sphenoid sinus is important in a variety of sinus surgical applications. These include assessments of a variety of inflammatory lesions such as mucocele and fungal infections, as well as tissue biopsy of a tumor within the sphenoid sinus using an endoscope or a microscope.…”

“…A p value < 0.05 was accepted as statistically significant. referred to the superior turbinate as a reliable anatomical landmark of the sphenoid sinus and its natural ostium [2,13,15,16,18]. Most reports state that the natural ostium of the sphenoid sinus is positioned medial to the superior turbinate [2,16].…”

“…Millar and Orlandi [15] reported that the natural ostium of the sphenoid sinus was medial to the superior turbinate in all of their 47 cadaveric specimens. Min et al [16] and Bolger et al [2] suggested that the superior meatus and superior turbinate were reliable landmarks for the sphenoid sinus in the transsphenoidal approach. In our study, the trans-superior meatal approach was performed in 154 patients with sellar lesions.…”
