Summary
Understanding the mandibular nerve
Area of Science:
- Anatomy
- Oral Surgery
- Radiology
Background:
- Knowledge of the mandibular nerve's intra-mandibular path is crucial for dental, stomatological, and maxillofacial surgery.
- Anatomical variations necessitate detailed understanding for surgical planning.
Purpose of the Study:
- To investigate the intra-mandibular course of the mandibular nerve using computed tomography.
- To provide precise anatomical data for surgical procedures involving the mandible.
Main Methods:
- Computed tomography scans of 14 mandibles were analyzed.
- Measurements were taken of the mandibular nerve's position relative to cortical layers and mandibular borders in vestibulo-lingual and vertical planes.
Main Results:
- The mandibular nerve courses near the vestibular and lingual cortical layers before exiting.
- In the crestal plane, the nerve is situated in the superior third of the mandible's inferior border.
Conclusions:
- Despite anatomical variability, a common path for the mandibular nerve exists.
- Pre-surgical imaging is essential for safe procedures near the mandibular nerve.
