Abstrakt: Objective: The promontory of the middle ear was recently suggested to be an appropriate site for diagnosing otitis media (OM) in archaeological bones by endoscopic inspection. The present study scrutinized the underlying assumption that a bulgy, irregular promontorial surface represents a pathological condition.
Materials: We compared an allegedly healthy individual and an allegedly diseased individual in skeletal remains of two human individuals from the early Medieval period in Germany.
Methods: The specimens were studied using microscopic analyses of thin ground sections.
Results: The osseous architecture of the three-layered promontorial wall was the same in both specimens. Both the contour of the resorption front of the middle layer and the thickness of the overlying outer periosteal layer showed some variation, resulting in an either smooth or a bulgy promontorial surface, while signs of resorptive or proliferative changes at the periosteal surface were missing in both cases.
Conclusions: Our results suggest that an irregular promontorial surface represents normal variation in the development of the otic capsule rather than a pathological condition. We therefore conclude that the promontory is not an appropriate site for diagnosing OM in archaeological bone.
Significance: The study contributes to evidence-based diagnoses in paleo-otological studies. Our assumption is in line with clinical and experimental findings indicating that the otic capsule is protected against bone remodeling.
Limitations: Only two specimens were studied.
Suggestions for Further Research: SEM-studies to detect more subtle changes to the promontorial surface.
