Superior semicircular canal dehiscence or SSCD

The cochlea is a part of the ear where sound waves travel through the hair cells and are converted into digital signals and then sent to the brain.

This cochlea is surrounded by the ear bone (malleus), a very strong bone - the hardest and most dense bone in the body - which provides a very good sound insulation. In that bone are two 'windows' looking out at the middle ear through which the sound waves enter.

When that insulating bone around the cochlea in one place is very thin, or even absent (dehiscent), this can have a very big impact on the acoustics of the ear. Such a dehiscence is called a 'third window'.

Usually it is about the bone above one of the semicircular-shaped channels of the equilibrium system (superior semicircular canal dehiscence or SSCD).

A 'third window' can cause autophony (the loud and unpleasant hearing of one's own voice), balance disorders, tinnitus, hearing loss, seeing the changing of the environment, hearing your own footsteps, hearing your own eyes moving, seeing objects moving to the rhythm of sounds,.

The combination of a 'third window' with an excitation of the central stress network can lead to the emergence of a number of other complaints.

How can Third Window Conditions be treated?

The third window can be closed with a surgical intervention.

Non-invasively, the acoustics of the ear can be adjusted by patching.

Neuromodulation can have a positive influence on the negative effects dehiscence has on the central network. A qEEG can help us determine which neuromodulation technique could have the most effect.
