How MED-EL Cochlear Implants Provide the Closest to Natural Hearing
What Is Closest to Natural Hearing?
Natural hearing uses the entire cochlea.[ft] So providing the best chance to fully benefit from CI technology means finding a cochlear implant that uses most of the cochlea. When you provide your patients with an implant individualized to fit their ear, preserve natural structures during implantation, and perform fitting to match tones to their natural places, you can provide your patients with the closest to natural hearing.
The Full Spectrum of Sounds
When more of the cochlea is covered by the electrode, each tone can be stimulated at its natural place. Mid-to-low tones can be heard and sound more natural when stimulated in the apical region as nature intended.[ft][ft][ft][ft] The result can be a more natural overall hearing experience for your patients.
Exceptional Sound Quality
More precise tonotopic pitch matching means your patients can have a better subjective hearing experience—especially when it comes to sound quality and music perception.[ft][ft][ft] This also makes combining acoustic and electric stimulation easier.[ft][ft]
Superior Hearing Performance
Preserving hearing structures, stimulating more of the cochlea, and more accurate pitch matching can lead to measurable benefits in objective hearing outcomes. This is especially true with speech understanding in noise and sound localization.[ft][ft][ft]
Best Benefit Quickly
Stimulating each tone closer to its natural place in the cochlea means less adaptation for your patients. Noticeable improvements and objective hearing benefits can be common in the first months of device usage.[ft][ft][ft]
Stimulating the Entire Cochlea
Including apical hearing structures and FineHearing to stimulate as nature intended
- Long electrodes can stimulate apical hearing structures located 1.5-2 turns in the cochlea
- FineHearing technology uses place and rate coding for improved sound quality
Your patients can hear the mid-to-low frequencies with fuller, more natural sound quality.
The Right Pitch at the Right Place
Matching pitches more precisely with individualized cochlear implants and anatomy-based fitting
- Anatomy-based electrode selection that fits the unique anatomy of each individual cochlea
- Fine-tune the place-pitch match through anatomy-based fitting
More informed decision-making for each individual patient and closer tonotopic match can improve pitch perception.
Hearing and Structure Preservation
Preserving hearing and hearing structures with flexible electrode arrays and precision surgery
- Flexible electrode arrays that can be atraumatically placed in the cochlea
- Precision surgery using tools for atraumatic, accurate cochlear implantation
- Electrodes proven to preserve residual low-frequency hearing
Your patients can experience better hearing performance, and the majority of patients can retain residual hearing.
Stimulating the Entire Cochlea as Nature Intended
Complete Cochlear Coverage
Inspired by nature, MED-EL’s cochlear implants aim to unlock the full potential of each ear by stimulating nearly the entire cochlea—up to 1.5 to 2 turns—to leave none of the spiral ganglion unused.
In fact, only MED-EL’s FLEX electrodes can reach beyond 1.5 turns.[ft][ft][ft][ft][ft][ft][ft] This provides access to the entire hearing range, so your patients can hear the mid-to-low frequencies below ~800Hz more naturally. Not only does stimulating more of the cochlea allow recipients to benefit from accessing the full spectrum of sounds, it also contributes to better speech perception.[ft]
Apical Stimulation With FineHearing
MED-EL’s unique FineHearing technology replicates natural hearing to provide superior perception of low frequencies. Just as natural hearing works in the cochlea’s second turn, FineHearing stimulates in the right place and at the right rate. This allows your patients to experience fuller, more natural sound quality.[ft][ft][ft][ft]
Cochlear implants with short electrode arrays can’t stimulate the apical region. When an electrode array is too short for the patient’s cochlea, this can lead to pitch confusion. As a result, a deep male voice may sound like Mickey Mouse—much higher than it should sound.[ft][ft]
The Right Pitch at the Right Place
Reducing pitch mismatch can improve hearing outcomes in the first weeks and months, helping your patients to adapt quicker to their cochlear implant.[ft][ft][ft] Patients with less tonotopic mismatch also tend to benefit more across the lifespan of cochlear implant usage when compared to peers with smaller degrees of mismatch.[ft] More precise pitch matching requires the right tools.
The Right Electrode for Each Cochlea Promotes Pitch Matching
Anatomy-based electrode selection, when an electrode array is selected based on the individual size of a cochlea, can provide pitch match closest to that cochlea’s specific natural tonotopic place-pitch map.[ft][ft][ft] That is why MED-EL offers the largest portfolio of soft, flexible arrays so surgeons can choose the ideal array for each ear. Standard preoperative imaging and OTOPLAN’s electrode visualization feature can help surgeons visualize how each electrode array would fit each patient’s unique cochlea.
Closest to Natural Pitch Perception With Patient-Specific Data
Even though our default frequency map is designed to follow the natural tonotopic map of the cochlea, not every electrode array ends up at the exact same location. Anatomy-based fitting lets you instantly calculate center frequencies based on the real post-op electrode location for individualized fitting of the frequency bands. When each electrode contact is correctly “fine-tuned” to the center frequency for its real pitch-place, you can provide your patients with more precise pitch matching.[ft][ft][ft][ft] This helps support the closest to natural pitch perception.
Hearing and Structure Preservation
Patients with residual hearing often fear losing what they still can hear without a device. We’ve listened to them and focused decades of research and development on producing the most atraumatic electrode arrays available that have been proven to preserve residual hearing for the majority of recipients.[ft][ft] This means patients can continue to enjoy their residual hearing and, in addition, gain the benefits from hearing with a MED-EL cochlear implant.
For surgeons, we provide precision surgery tools for cochlear implantation to help maximize structural preservation. Why? Because, along with electrode design, surgical factors such as insertion trajectory and speed also contribute to reaching optimal outcomes.[ft][ft][ft]
Soft, Flexible Electrode Arrays
MED-EL’s FLEX lateral wall electrode arrays have been shown to preserve inner ear structures and residual hearing for the majority of patients.[ft][ft] Not only can this provide better hearing performance, but this will also give these patients the opportunity to benefit from future therapies and technologies.
Our FLEX electrodes offer the ideal mix of mechanical flexibility and channel spacing. The flexibility gained by adding more space between contacts means the electrode arrays can be atraumatically inserted deeper into the cochlea with reduced insertion force. More spacing also helps to avoid overlapping stimulation channels or crosstalk.[ft][ft][ft]
Precision Cochlear Implantation
As the leading global innovator of hearing implants, we understand the need for precision tools to help you maximize structural preservation. That’s why we provide tools like OTODRIVE and OTOARM to enable slow, steady, and precise electrode array movement during implantation.*
These precision surgical tools were specifically designed to ensure that the electrode array is slowly placed within the cochlea. This approach can reduce the risk of trauma, help preserve remaining natural hearing, and improve overall hearing outcomes by optimizing implant placement.[ft][ft]
Electrodes Proven to Preserve Residual Hearing
Now the only cochlear implants on the market FDA-approved for hearing preservation, MED-EL’s FLEX electrode design allows the majority of recipients to retain some functional natural hearing post-implantation.[ft]
The preservation of residual low-frequency hearing was proven with the MED-EL FLEX electrode portfolio, including long electrodes such as FLEX28 and FLEXSOFT.[ft][ft] This means MED-EL FLEX electrode arrays provide the best opportunity to preserve residual hearing for your patients.
