“…However, there was no statistical relationship between races and sphenoid types (Hindi et al). Due to these data in males we found some differences in the prevelance of the sphenoid sinus types of Brazilians, Egypt, Indian populations and Turkish population with our healthy female and male population (Kayalioglu et al;Hamid et al;Budu et al, 2013;Mamatha et al;Yamashita et al;Vidya & Raichurkar). Our result of the least sphenoid sinus type which was conchal type was in concordance with literature (Kayalioglu et al; Sareen et al; Hamid et al; Mamatha et al; Hindi et al; Vidya & Raichurkar).…”

“…It is bordered at the many serious structures like cavernous sinus laterally, the eithmoidal air cells, anterior cranial fossa and optic nerve anteriorly, the clivus posteriorly, the hypophysis fossa and planum sphenoidale superiorly, choana inferiorly, internal carotid artery medially (Mamatha et al;Seddinghi et al, 2014;Sevinc et al;Farımaz et al, 2018). Sphenoid sinus shows difference in size, shape and degree of pneumatization (Yamashita et al, 2014). Variations in septation, shape, and dimensions have a serious effect on surgical planning of the skull base (Wiebracth & Zimmer).…”

The aim of this study was to identify sphenoid sinus dimensions; and distance between columella nasal and sphenoid sinus; and columella nasal and hypophysis in healthy adult subjects using magnetic resonance imaging (MRI) and to evaluate differences between genders and age groups. The MRI results of 300 healthy subjects (192 females; 108 males) aged 18-68 years were studied. The midsagittal and axial images were used for shape of the sphenoid sinus, and the distance measurements of its related adjacent structures on MRI. The mean values of the distance between columella nasal; and columella nasal and hypophysis; and sinus sphenoidalis width were 65.73±5.22 mm, 87.05±4.79 mm and 37.67±8.40 mm in females respectively, whereas the same values were 71.79±5.06 mm, 94.52±6.07 mm and 41.95±9.32 mm in males, respectively. The means of all measurements were lower in healthy female subjects than in healthy males.Additionally, the classification of sphenoid sinus types were determined to be postsellar type (131), sellar type (46), presellar type (14) and conchal type (1) in females, respectively. The same measurement were determined as postsellar type (82), sellar type (23) and presellar type (3) in males, respectively. Differences between sexes and age related changes were observed in the variations of the size, location and shape of sphenoid sinus were observed The observations presented in this report have defined anatomic parameters that need to be taken into consideration for reference data to determine gender discrepancies, age related changes and helpful for radiologists and clinicians to plan safe surgical approach and avoid surgical risks.

Sella turcica is a saddle-shaped depression located in the middle cranial fossa on the upper surface of the sphenoid bone. It is enclosed by the pituitary fossa in which the pituitary gland is lodged, tuberculum sellae on the front and dorsum sellae in the rear. [1][2][3][4] Two anterior and two posterior clinoid processes form a protrusion on the pituitary fossa, and these are the structures that protect the pituitary gland in the sella turcica. The extensions of the sphenoid bone's ala minor to the anterior and medial form the anterior clinoid processes.The endings of the dorsum sellae form the posterior clinoid processes. [1,4,5] Sella turcica is a bony structure that is closely related with the pituitary gland, and is of both anatomical and clinical importance. The sellar and parasellar regions are anatomically complex structures where neoplastic, infectious, inflammatory, developmental and vascular pathologies may develop. [2,6] Research on sella turcica focuses not only on its dimensions, but also on its morphology. Sella morphology is important in both evaluating treatment outcomes AbstractObjectives: Morphometry of sella turcica should be known to evaluate pathological sella turcica. The aim of this study was to measure the size and describe the morphology of sella turcica in a Turkish population.Methods: This study included 101 individuals aged 17 to 70 years who went under CT scan. Sella length, sella width, sella height anterior, sella height median, sella height posterior, sella area, sella depth and sella anteroposterior (AP) diameter were measured.Results: Sella length was measured as 9.18±1.91 mm, sella width 10.41±1.74 mm, sella height anterior 8.09±1.65 mm, sella height median 7.71±1.24 mm, sella height posterior 7.48±1.34 mm, sella area 69.15±17.45 mm 2 , sella depth 7.87± 1.37 mm and antero-posterior sella diameter as 11.48±1.82 mm. When these sizes were compared between males and females, only sella length and width differed significantly. When compared by decades, there was a statistically significant difference only in the sella area parameter. Conclusion:Sella turcica dimensions of the Turkish population obtained by CT in this study can be used in estimating pituitary gland size and in determining any pathology in the sellar and parasellar regions. In addition, these results may help clinicians who encounter pathologically large sella areas in easily distinguishing it. Therefore, knowing the normal anatomy and variations of sella turcica is important for neurologists and neurosurgeons who deal with the pathologies of this area.

“…To maintain the accuracy of the research, we divided all patients by gender into 3 age groups: 20-40 years old, 41-60 years old, and over 60 years old, similar to Seizo Yamashita's research [19]. However some authors, for example, B. Anusha et al, 2015, [20] included patients starting from 18 years old into the research scope, and Davudi et al [21] as well as Heiwaidi et al [22] expanded their researches starting from 16 years aged patients.…”

For the period of 2019, magnetic resonance imaging of the head of patients aged 20–71 years was performed. The majority of males have mezocran the shape of the skull, in contrast to females. There was no universal type of pneumatization for both sexes. In young men, the sellar type prevails, but at the age of 60, this type is 2 times less common and there are no protrusions of the channels of the optic nerves and internal carotid arteries. However, only the protrusion of the internal carotid artery channel is more common in women over 60 years of age than in men. In men, there were no cases of canal protrusion, and 49% of young women had a depression in the wall of the sphenoid sinus. In men under the age of 60, the protrusion of the optic nerve channels and internal carotid arteries occurs in approximately the same way as in women over 80 years of age. Due to the variability of the anatomical configuration of the sphenoid sinuses, the impact on access to the cell through the nose can be serious. The surgeon must be aware of these results before surgery in order to reach the cell safely and effectively.
