By: Oticon Medical
Date: 13 September 2018

The latest reliability data shows how Neuro ZTi offers outstanding reliability – with an impressive Cumulative Survival Percentage (CSP)* of 99.96% at three years1. With this new data, patients considering the Neuro cochlear implant system can confidently cross reliability off their list of concerns.

The new Cumulative Survival Percentage (CSP) rating firmly places the Neuro Zti among the most reliable cochlear implants in the industry1,2,3,4.


Implants with up to five years reporting

Neuro ZTI reliability

The high reliability of the Neuro Zti builds on the strong Oticon Medical tradition of implant design with an extreme focus on detail. This is reflected in the CSP ratings of previous implants. For example, the Oticon Medical Digisonic SP Classic has a CSP of 97.16% after thirteen years while the EVO variant achieves an impressive 98.69% after six years.


Tested, tested and tested again

These figures reflect the utmost importance we have always given to reliability. Our development team works tirelessly to make sure that our implants deliver today, tomorrow and for many years to come. This means carrying out a wide array of tests – from the pillow test that simulates turning over in bed, to the electrode array 15mm stretch test and the impact test.

You can see how these tests are carried out in our reliability video.

At Oticon Medical, we understand that choosing a cochlear implant is about more than just the highest level of sound quality. Your patients need to feel secure that their implant is not going to let them down. These recently released reliability figures confirm that you can have full peace of mind with the Neuro Zti.
