Summary
Coronal computed tomography (CT) scans are crucial for assessing patients before functional endoscopic sinus surgery (FESS). Accurate correlation of radiological and surgical anatomy improves FESS precision and patient safety.
Area of Science:
- Radiology
- Otolaryngology
- Surgical Anatomy
Background:
- Coronal computed tomography (CT) plays a vital role in preoperative assessment for functional endoscopic sinus surgery (FESS).
- Understanding the anatomical framework is essential for safe and precise surgical navigation.
- Radiological imaging aids in correlating anatomical structures relevant to FESS.
Purpose of the Study:
- To review the conceptual anatomical framework underpinning functional endoscopic sinus surgery (FESS).
- To highlight the importance of coronal CT in preoperative planning for FESS.
- To enhance the understanding of radiological-surgical anatomy correlation for FESS.
Main Methods:
- This is a pictorial essay.
- Review of anatomical concepts relevant to FESS.
- Emphasis on coronal CT findings and their surgical implications.
Main Results:
- Coronal CT provides a detailed map of sinonasal anatomy crucial for FESS.
- Accurate radiological-surgical correlation enhances surgical precision.
- Familiarity with anatomical variations seen on CT aids in avoiding intraoperative complications.
Conclusions:
- Coronal CT is indispensable for the preoperative assessment of patients undergoing FESS.
- A thorough understanding of sinonasal anatomy visualized by CT improves surgical outcomes.
- This review provides a foundational anatomical basis for performing FESS effectively and safely.
