Objective:
This study was performed to determine the dimensions of the sella turcica (ST) in relation to sex, age groups, and sphenoid sinus (SS) pneumatization patterns in a cohort of Iraqi individuals.
Methods:
This cross-sectional study analyzed computed tomography images of 99 individuals (53 men, 46 women) aged 24 to 59 years to measure ST dimensions, including length, width, height, depth, and surface area. SS pneumatization was classified by sex and age. We also examined the relationship between ST size and SS pneumatization patterns.
Results:
Women exhibited a significantly greater mean ST depth (9.37 mm) than men (8.19 mm). The ST diameter was significantly larger in the middle-aged group (13.1 mm) than in the young adult group (11.83 mm). The ST area showed a highly significant difference between sexes. The sellar pneumatization pattern was the most common, whereas the conchal pattern had the lowest prevalence. A significant correlation was observed between ST size and SS pneumatization.
Conclusion:
The ST depth and diameter showed statistically significant differences across sex and age groups, respectively. The variability in SS pneumatization patterns underscores the importance of considering pneumatization types during surgical planning to minimize the risk of iatrogenic injury and improve treatment outcomes.

01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
