Summary
The human hyoid bone
Area of Science:
- Anatomy
- Biomechanics
- Anthropology
Background:
- The hyoid bone's position is conventionally described.
- Understanding its anatomical variations is crucial for biomechanical analysis.
Purpose of the Study:
- To investigate the anatomical variations in the human hyoid complex.
- To analyze the positional relationship of the hyoid bone to mandibular landmarks and musculature.
Main Methods:
- Dissection of forty human hyoid complexes.
- Measurement of bony landmarks and muscle parameters.
- Statistical analysis of collected data.
Main Results:
- The hyoid's long axis is parallel to the mandible in only 30% of cases.
- 30% exhibit an oblique ascending hyoid course (>20 degrees).
- 40% show the hyoid bone positioned higher, close to the mental symphysis.
Conclusions:
- Significant anatomical variations exist in the human hyoid complex.
- Observed variations, including sexual dimorphism, impact the hyoid's functional position.
- Clinical and normal assessments must consider these anatomical discrepancies.
