Abstract:
With the expanding use of the functional endoscopic sinus surgery (FESS), proper understanding of the sphenoid sinus anatomy has become increasingly important. Knowledge of the size and extent of pneumatization of sphenoid sinus is an important to avoid any complications during surgery.
This descriptive study was conducted in Sudan - Khartoum to study the anatomical variations of sphenoid sinus among Sudanese using ct scan. 70 images of ct for para nasal sinus (35males and 35females) were evaluated in both axial and coronal plane; their ages were ranged from 18 to 58 years old. Data were compared statistically using spss programe with relation to age and gender of the patients.
The result of the study showed that the type for most of participants was sellar (73.58%) in both right and left sinuses, (36.42%) of them were presellar, while (0%) of them were conchal for both sinuses. It also showed that the pneumatization in sinus is independent on age and gender
