Summary
Anatomical variations in the sphenopalatine foramen (SPF) region were studied in 61 cadavers. Findings highlight lateral nasal wall differences crucial for endoscopic surgery success.
Area of Science:
- Anatomy
- Surgical Anatomy
- Endoscopic Sinus Surgery
Background:
- The sphenopalatine foramen (SPF) is a critical anatomical landmark.
- Understanding its variations is essential for surgical procedures, particularly in managing severe epistaxis.
Purpose of the Study:
- To detail the anatomy of the sphenopalatine foramen (SPF) region.
- To identify and describe anatomical variations within the SPF region.
Main Methods:
- Prospective dissection of 61 cadavers (122 nasal fossae).
- Analysis of ethmoidal crest presence, SPF and accessory foramen location, and arterial branching.
- Evaluation of variations in relation to gender, race, and nasal symmetry.
Main Results:
- Ethmoidal crest present in 100% of cases, anterior to SPF in 98.4%.
- SPF most commonly located at the middle/superior meatus junction (86.9%).
- Accessory foramens found in 9.83% of cases; no significant differences by gender or race.
Conclusions:
- Significant anatomical variations exist in the lateral nasal wall.
- These variations, particularly concerning the SPF, must be considered for successful endoscopic surgical interventions for severe epistaxis.
