If your hearing loss is due to problems in your outer or middle ear, ask your hearing care professional about bone anchored devices. Specifically designed to bypass any problems in the ear canal or middle ear, these devices may offer you far clearer, more natural listening.
Conductive or mixed hearing loss
There are three main types of hearing loss; sensorineural hearing loss, conductive hearing loss and a combination of the two referred to as mixed hearing loss.
- Sensorineural hearing loss
means that there is a problem in the inner ear (cochlea) or auditory nerve.
- Conductive hearing loss
happens when an obstacle somewhere in the outer and/or middle ear stops airborne sound waves from reaching your inner ear.
- Mixed hearing loss
is a combination of sensorineural and conductive hearing loss
In cases of conductive hearing loss: By transmitting the sound directly to the inner ear via the skull bone – without it having to pass through the ear canal and middle ear – the Ponto system completely bypasses these obstacles.
In cases of mixed hearing loss: The Ponto system concentrates on compensating for the sensorineural hearing loss without having to first break through the ‘road block’ in the ear canal or middle ear. The result is clearer, more natural sound quality.
In cases of sensorineural hearing loss: A bone anchored hearing system will not be the best solution – unless you have eczema in your ear canal and cannot wear a conventional hearing aid.
If you are deaf in one ear then the Ponto system might also be a good solution, see single-sided deafness.
Infections, irritation & draining ears
Conductive hearing loss is often caused by chronic ear infections. These can be aggravated by conventional hearing aids as they physically block the ear canal, which increases the risk of irritation and infection. With a bone anchored device these problems can be reduced or avoided, as the ear canal is always open.
Malformations of the outer ear
Another common cause of conductive or mixed hearing loss is atresia, a malformation of the outer ear where the ear canal is either missing or very narrow.
