Summary
Sphenoid sinus variations are common. A new classification of sphenoid sinus pneumatization in a Turkish population reveals postsellar as the most frequent type, aiding surgical planning.
Area of Science:
- Anatomy
- Radiology
- Otolaryngology
Background:
- Sphenoid sinus variations are diverse and frequent.
- Detailed anatomical knowledge is crucial for sphenoid sinus surgeries, like pituitary surgery.
Purpose of the Study:
- To propose a new detailed classification for sphenoid sinus pneumatization.
- To evaluate the incidence of different pneumatization types in a Turkish population using this classification.
Main Methods:
- A novel classification system for sphenoid sinus pneumatization was developed.
- Cone-beam computed tomography (CBCT) scans of 128 patients were analyzed according to the new classification.
Main Results:
- Posteroanterior pneumatization showed high incidence of postsellar (57.8%) and sellar (35.9%) types.
- Lateral pneumatization was most commonly of the lateral body type on both sides (44.1% right, 42.5% left).
- Anterior pneumatization was observed in 28.9% on the right and 23.4% on the left.
Conclusions:
- A new classification for sphenoid sinus pneumatization was proposed based on 3D CBCT analysis.
- Understanding these variations is vital as they can impact surgical approaches and planning.
- Paranasal sinus variations necessitate careful consideration due to their surgical significance and proximity to vital structures.
