Summary
The agger nasi cell approach provides effective access to the frontal recess for endoscopic sinus surgery. This method aids in identifying the frontal ostium and leads to successful sinus healing.
Area of Science:
- Otolaryngology
- Endoscopic Sinus Surgery
- Anatomy
Background:
- Frontal recess access is crucial for endoscopic frontal sinus surgery.
- Identifying anatomical landmarks like the agger nasi cell and uncinate process is key.
Purpose of the Study:
- To evaluate the efficacy of the agger nasi cell and uncinate process identification for accessing the frontal recess.
- To assess the success rate of endoscopic frontal sinus surgery using these anatomical landmarks.
Main Methods:
- Computed tomographic (CT) scans were used to identify the frontal ostium via agger nasi cell or uncinate process approach.
- Study included 47 patients (85 sides) undergoing endoscopic frontal sinus surgery.
Main Results:
- The frontal ostium was successfully identified in 100% of cases.
- Sinus healing rates were 84% (agger nasi cell approach) and 81% (uncinate process approach) at 9-month follow-up.
Conclusions:
- The agger nasi cell approach offers reliable access to the frontal recess and frontal ostium.
- This technique allows direct endoscopic visualization, facilitating successful surgical outcomes.
