Summary
This study successfully decalcified and sectioned a mummy temporal bone, revealing signs of middle ear and mastoid infections. The novel technique aids paleopathology research on ancient ear conditions.
Area of Science:
- Paleopathology
- Otopathology
- Bioarchaeology
Background:
- Studying ancient diseases requires advanced techniques for preserving delicate biological samples.
- Temporal bones offer insights into health and disease in past populations.
Observation:
- A mummy temporal bone was processed using modified decalcification and serial sectioning.
- The bone's fragile state necessitated adaptations to standard histological methods.
Findings:
- The serial sections showed clear evidence of middle ear infection (otitis media) and mastoiditis that occurred during the individual's lifetime.
- This is the first reported successful processing of a mummy temporal bone using these methods.
Implications:
- The described technique is valuable for otopathological research on paleontological specimens.
- This method can enhance our understanding of ancient ear diseases and their prevalence.
