Characterization of sphenoid sinuses for Sudanese population using computed tomography

Area of Science:

• Anatomy
• Radiology
• Otorhinolaryngology

Background:

• The sphenoid sinus is a complex anatomical structure.
• Understanding its variations is vital for safe surgical interventions.

Purpose of the Study:

• To characterize the anatomical features of the sphenoid sinus in a Sudanese population.
• To provide essential anatomical data for clinical surgical practice.

Main Methods:

• Computed tomography (CT) scans of 100 Sudanese subjects were analyzed.
• Seven horizontal and vertical measurements of the sphenoid sinus were evaluated.
• Presence of Onodi cells and pneumatization patterns were documented.

Main Results:

• Onodi cells were observed in 13% of subjects (10% sellar, 3% pre-sellar).
• Sellar pneumatization occurred in 85% of cases, with 15% pre-sellar.
• Detailed mean measurements for sinus dimensions (depth, width, wall distances) were recorded, with noted gender differences.

Conclusions:

• The study establishes normative anatomical data for the sphenoid sinus in Sudanese individuals.
• These findings are significant for improving surgical outcomes and reducing complications in the region.
