Evidence of otitis media and mastoiditis in a Medieval Islamic skeleton from Spain and possible implications for ancient surgical treatment of the condition.

OBJECTIVE

To evaluate lesions on a cranium from the Iberian Peninsula and assess its medico-historical and paleopathological significance.

MATERIALS: The skeletal remains of a juvenile individual found in a Medieval Islamic grave (10th -16th century) in Eastern Spain.

METHODS

Macroscopic examination of the left and right temporal bones, binocular microscopy, X-ray, and Scanning Electron Microscopy - Energy Dispersive X-ray Spectroscopy (SEM-EDS) were performed.

RESULTS

A sub-oval perforation superior to the right mastoid process and pathological changes on the right temporal bone were identified. SEM-EDS confirmed the presence of copper in the surrounding area of the perforation.

CONCLUSIONS

The observed pathological changes are most likely compatible with otitis media and subsequent mastoiditis. The sub-oval perforation could be interpreted either as an abscess or as evidence of a surgical procedure (mastoidectomy) or a combination of both; and the Cu traces may be the result of an associated object or, possibly, the application of a plaster with copper acetate used as medical treatment.

SIGNIFICANCE: This case contributes to the paleopathological record and the interpretation of similar cases, and also helps in the understanding of medical care and treatment in Medieval Islam.

LIMITATIONS: The lack of similar pre-modern cases of surgical intervention limits comparability to clinical cases. Suggestion for further research: Exploration into indicators of health care in past populations.
