Summary
This study provides crucial anatomical reference distances for functional endoscopic sinus surgery. Surgeons can use these measurements to safely navigate the nasal cavity and ethmoid labyrinth, minimizing risks to vital structures.
Area of Science:
- Otorhinolaryngology
- Surgical Anatomy
- Endoscopic Sinus Surgery
Background:
- Functional endoscopic sinus surgery (FESS) is increasingly common worldwide.
- Precise anatomical knowledge of the nasal cavity and ethmoid labyrinth is critical for FESS safety.
- Avoiding complications requires understanding the spatial relationships of key structures.
Purpose of the Study:
- To establish reference distances for anatomical landmarks relevant to FESS.
- To aid endoscopic sinus surgeons in surgical planning and execution.
- To enhance patient safety by providing critical anatomical data.
Main Methods:
- A surgical anatomical study involving 50 cadavers.
- Measurements of specific anatomical landmarks from the anterior nasal spine.
- Utilized endoscopic visualization and a straight surgical guide for precise measurements.
Main Results:
- Key reference distances for critical anatomical landmarks were determined.
- Identified specific distances to vital structures like the optic nerve and internal carotid artery.
- Established spatial data for the lateral nasal wall relevant to FESS.
Conclusions:
- Surgeons must be aware of critical anatomical distances during FESS.
- Particular attention is needed for the optic nerve and internal carotid artery beyond 75 mm at the posterior rhinobasis.
- These anatomical references are vital for safe and effective endoscopic sinus surgery.
