Summary
Bony variations in the nasal cavity are common in patients with and without sinus disease. These anatomical differences are crucial for otolaryngologists performing functional endoscopic sinus surgery.
Area of Science:
- Anatomy
- Radiology
- Otolaryngology
Background:
- Nasal cavity variations are critical for otolaryngologists performing functional endoscopic sinus surgery (FESS).
- Understanding bony anatomy aids in surgical planning and patient outcomes.
Purpose of the Study:
- To provide detailed data on bony variations of the paranasal sinuses.
- To correlate these variations with sinus disease and guide FESS procedures.
Main Methods:
- High-resolution computed tomography (CT) scans of paranasal sinuses were analyzed.
- 82 adult patients without sinus pathology and 90 adult patients with sinus disease were included.
Main Results:
- Prevalence of paradoxical middle concha curvature, concha bullosa, deviated nasal septum, Haller's cell, and agger nasi cell were recorded.
- Pneumatization of crista galli, anterior clinoid process, nasal septum, and pterygoid recess were observed.
- No significant correlation found between age or sex and paranasal sinus variations.
Conclusions:
- Prevalence of certain bony variations differs between patients with and without sinus disease.
- CT-based anatomical data is vital for guiding otolaryngologists and radiologists in FESS.
- Accurate anatomical assessment improves surgical precision and patient care.
