Summary
This study details the macroscopic and microscopic anatomy of the oral modiolus, revealing its tortuous, cone-like shape. This 3-D anatomical information aids surgeons in oral commissure procedures.
Area of Science:
- Anatomy
- Oral Surgery
Background:
- The modiolus is a fibromuscular structure crucial for oral commissure function.
- Detailed 3-D anatomical data of the modiolus is limited.
Purpose of the Study:
- To provide comprehensive macroscopic and microscopic anatomical details of the modiolus.
- To elucidate the three-dimensional (3-D) shape of the modiolus.
Main Methods:
- Serial sectioning (15 micrometers) of fixed cadaveric tissue.
- Hematoxylin and eosin, and Massons' trichrome staining.
- Digital imaging and 3-D reconstruction for anatomical analysis.
Main Results:
- The modiolus is a tortuous, blunt cone extending vertically from buccal mucosa to skin dermis.
- Its base is situated adjacent to the oral mucosa.
Conclusions:
- The modiolus possesses significant clinical importance in oral commissure surgery.
- This study's histological and 3-D analysis offers valuable insights for surgeons.
- Improved understanding facilitates better esthetic and functional surgical outcomes.
