Functional morphology of the pterygoid hamulus
Summary
The pterygoid hamulus (PH), a poorly described skull base structure, exhibits variable morphology and biomechanical loading. This study provides detailed anatomical data to understand its function and potential for irritation.
Area of Science:
- Anatomy
- Biomechanics
- Histology
Background:
- The pterygoid hamulus (PH) is an under-described structure at the skull base.
- Its biomechanical situation is peculiar and not well understood.
Purpose of the Study:
- To gather morphological data on the pterygoid hamulus (PH) for functional interpretation.
- To investigate the PH's relationship with surrounding muscles.
Main Methods:
- Examination of 93 adult and 24 child skulls, plus 20 heads.
- Morphometric measurements using a sliding gauge.
- Histological examination of methyl methacrylate-embedded sections.
Main Results:
- The PH is a variable structure, classifiable into basic types.
- Average measurements: length 7.2 mm, sagittal breadth 1.4 mm, transverse breadth 2.3 mm.
- Histology reveals differential cortical thickness and collagen fiber angles, suggesting specific loading patterns.
Conclusions:
- The PH's structure supports medio-dorsal loading on its body and lateral/caudal pulling on its head.
- Its exposed position and associated bursa/sliding layer indicate potential for irritation.
