Summary
Computed tomography (CT) scans provide reliable measurements for endoscopic sinus surgery. These measurements accurately reflect the distance to the anterior skull base, ensuring safe surgical access.
Area of Science:
- Otolaryngology
- Neurosurgery
- Medical Imaging
Background:
- Nasal endoscopic surgery treats paranasal sinus and skull base diseases.
- Accurate anatomical references are crucial for surgical safety.
Purpose of the Study:
- To measure and compare the distance from the maxillary sinus posterior wall to the anterior skull base.
- To establish imaging-based anatomical references for sinus and skull base surgery.
Main Methods:
- Measurements were taken from the maxillary sinus posterior wall (point A) to the anterior sphenoid wall (point B) in 51 cadavers.
- Data collected via dissection and computed tomography (CT) scans.
Main Results:
- Measurements in both CT scans and dissections exceeded 1.5 cm in all cadavers.
- CT measurements showed a positive correlation with dissection measurements, indicating reliability.
Conclusions:
- CT measurements serve as a dependable tool for safe and effective endoscopic sinus and skull base surgery.
- CT imaging accurately guides dissection to the anterior skull base.
