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

Objective: 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.

Conclusions: 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.
