About the Procedure

Who can benefit from a cochlear implant?

Patients are evaluated on the benefit they would receive from a cochlear implant through a series of hearing tests and neurological scans. A case manager is assigned to each patient to work with them through this process.

Before we can offer advice on the suitability of a cochlear implant for someone, the following aspects need to be considered: age and health of the patient, formation and function of the inner ears and auditory nerve (some causes of deafness can result in abnormal bone growth inside the cochlea, and this could make the ear unsuitable for the cochlear implant operation). We also consider hearing levels in both ears, the benefit the patient gains from their hearing aids, and their current speech perception and communication skills.

A number of assessments are required in order to determine the suitability of each prospective candidate for the cochlear implant operation. The results of these tests also allow the clinicians to advise people on the benefit they may gain from the device. The normal battery of assessments includes:

• a CT scan
  
• MRI scan,
  
• several hearing tests (with and without hearing aids)

This data is collated, and before surgery goes ahead the case manager and patient discuss the benefits the patient may gain from a cochlear implant.

Having realistic expectations
In addition, it is essential that people and families considering a cochlear implant have realistic expectations of the device and outcomes for the patient. The implant does not return hearing to normal, and the sounds produced by a cochlear implant may not be the same as the patient remembers them. With time and practice, however, the new sounds should be recognizable. Before a patient or family decides to proceed with surgery, it is important that the limitations of the device are explained fully. The case manager will answer any queries and will arrange meetings with people and their families who have already had the operation and are willing to share their experiences.

It is also important to be aware of the impact of the cochlear implant on self and family. A clinic social worker is available to discuss the broad implications of the operation and the many adjustment issues with the prospective candidate. Many families take advantage of the opportunity to see the social worker to discuss personal and family expectations of the device and how these may affect their lifestyle.
