Double dehiscence (Superior semicircular canal and tegmen tympani) in the epicampaniform period (Arboli type).

PURPOSE

Although the superior semicircular canal dehiscence syndrome was described at the end of the 20th century, we want to check if it is a pathology that has existed since ancient times, through the anthropological study of bone remains.

METHODS

We have carried out an anthropological and radiological study (CT scan) of 8 skulls found in caves, as secondary burials of the Arbolí type epicampaniform culture (1800 - 1700 BC) on the Iberian Peninsula.

RESULTS

The 8 skulls (16 temporal bones) show a grade 4 degree of pneumatisation or hyperpneumatization. One of these skulls, belonging to a male subject of around 25-30 years of age, shows a double dehiscence (superior semicircular canal and tegmen tympani) on the right side, and a possible congenital muscular torticollis on the same side.

CONCLUSION

Superior semicircular canal dehiscence syndrome already existed in an inhabitant from 1800 - 1700 BC (Iberian Peninsula). This is the first case in which the association of both dehiscences (superior semicircular canal and tegmen tympani) has been demonstrated.
