Summary
This study details posterior maxillary anatomy for safer Le Fort I osteotomies. Understanding these anatomical landmarks helps surgeons avoid damaging the descending palatine vessels during surgery.
Area of Science:
- Anatomy
- Oral and Maxillofacial Surgery
- Surgical Anatomy
Background:
- Hemorrhage during maxillary osteotomies commonly occurs in the posterior maxilla.
- A thorough understanding of this region's anatomy is crucial for minimizing vascular complications.
Purpose of the Study:
- To investigate the detailed anatomy of the posterior maxilla.
- To establish safety guidelines for performing Le Fort I osteotomies.
Main Methods:
- Analysis of 30 dry human skulls using direct measurement and computerized imaging.
- Detailed measurements of key anatomical landmarks in the posterior maxilla.
Main Results:
- Identified synosteosis in 10% of the pterygomaxillary junctions.
- Provided precise measurements for the pterygomaxillary junction height, maxillary tuberosity distances, and the descending palatine canal.
- Determined the width of the pterygoid process and distances to the zygo-alveolar ridge and nasal spines.
Conclusions:
- The findings enhance understanding of posterior maxillary anatomy relevant to Le Fort I osteotomy.
- Established clinical safety guidelines to prevent injury to the descending palatine vessels.
