Allison Lenear, AuD, lost her hearing due to repeated ear drum perforations. After multiple ear infections rendered her hearing aid for one ear ineffective, she decided to try Oticon Medical’s Sentio™ System. Here she shares her experience from the unique perspective as both a hearing care professional and a patient.

Early Experience with Hearing Loss Led to Early Advocacy

My hearing loss is the result of chronic ear drum perforations left after many Pressure Equalization (PE) tube placements. At the age of 15, after four failed tympanoplasties (two on each side), I was fitted with binaural hearing aids by my audiologist. He asked, “Aren’t you tired at the end of the day?” which I thought was just a teenager thing!

My hearing aids helped me hear and understand better in class, be more confident when working my afterschool job, and improved my ability to hear whispers backstage as a stage manager in my high school’s theater department. It was at that time I decided I wanted to be the person to help other people in my position accept their hearing loss and feel confident advocating for themselves. When classmates or strangers asked, “What are those things behind your ears?” I was never offended or embarrassed; it was an excellent way to start educating people around me that hearing aids are not only for older adults.

Accepting the Need to Move Beyond Traditional Hearing Aids

I graduated with my Doctor of Audiology degree from the University of Louisville in 2017 and started working as an audiologist at ENT of Athens, where I’d completed my fourth-year externship the previous year. I hadn’t had many ear infections as an adult, meaning there was no issue with traditional amplification. However, within the past two years, I started developing frequent bacterial and fungal infections, especially in the left ear. I wasn’t able to wear my hearing aid in that ear while being treated for the infection, making it difficult to hear and understand my patients. Each time I had an infection, it meant going about two weeks unaided on the affected side. It increased my stress, made the strain to hear and understand more difficult, and made me start avoiding things I love to do because it was so exhausting having to strain to hear. Because of this, I started thinking about a bone anchored solution.

Over the years, I’ve tried pretty much any new hearing aid that came out from all six major manufacturers but always ended up coming back to Oticon. I knew that for any sort of bone anchored device, especially when choosing to surgically implant it, I wanted the incredible sound quality, dependability, and reliability that I had come to rely on. So, when the Sentio™ System received FDA approval in the US, I knew I wanted to make the leap. It took some time to get it approved through the hospital, but on July 3, 2025, I became the first recipient in Athens, GA to receive the Sentio, courtesy of my physician and friend, Dr. Jacline Phillips.

My only concern before surgery was that I would be the first transcutaneous bone anchored hearing system recipient in the facility I had the surgery in! I was confident in my surgeon, who had performed many bone anchored hearing surgeries (percutaneous and other manufacturers’ transcutaneous devices), but the surgical team in the operating room was unfamiliar with them. Luckily, between Dr. Phillips and our Oticon Medical Territory Manager, Dr. Dianna Tingle, everything went off without a hitch.

Undergoing the Sentio Procedure and Processor Fitting

Dr. Phillips mentioned how much easier the Sentio was to implant versus competitors’ products. My incision was much smaller than I anticipated and lined up almost exactly with where my current tympanoplasty scars were located (behind my ear).

Recovery was extremely easy. I had surgery on Thursday and went back to work on Monday. Would I recommend that for everyone? Absolutely not! The only unforeseen issue was that I wear glasses and do not have contacts. So, when I wore my headset to perform hearing evaluations, the arm of my glasses pressed against my beautifully stitched incision and caused some discomfort. I was able to utilize the free accessory included with the Sentio, the EduMic, and connect it to my hearing aid on the right side to be able to hear patients while they were in the test booth, which eliminated pressure from the headset. I continued using that system for about a week after my stitches were removed. Since that time, I have had no pain or discomfort around the surgical site—it is almost like it never happened.

The two weeks leading up to my surgery, I had a fungal infection in the left ear and was unable to wear my hearing aid. I patiently waited two-and-a-half weeks before fitting the Sentio 1 Mini processor [Note: see video snippet below taken during Allison’s fitting session]. Since I was the first to receive a Sentio in our practice, Dr. Phillips, my colleagues, the office manager, and even Dianna came for the fitting. My colleague, who I consider “my” audiologist, was out of the country for vacation and FaceTime’d into the appointment as well!

Feeling Confident with the Sentio 1 Mini

Not having worn any type of amplification for the two weeks leading up to surgery (and more than two weeks after), it was really emotional and an enormous relief to be able to hear from my left side again. Initially, the sound quality was a little different with just my Sentio on, but when I put my right hearing aid in (a pink Oticon REAL™ 1 miniRITE-T with sparkly, swirly ear mold, of course), the sound quality was essentially exactly what I was used to with binaural air conduction amplification. I was able to localize sounds and hear again!

The day after my fitting, I went on a walk with a friend, who is an audiologist, and her linguist husband through our neighborhood. She and I were walking side by side and when I realized that, even though her husband was walking behind us, I could still hear and understand what he was saying… it was unbelievable. I was also able to hear cars and bikes coming from behind, which had been a safety concern of mine in the past when walking alone. Sentio has given me the freedom and the confidence to feel safe walking alone outside. It is absolutely lifechanging.

I love Made for iPhone® (MFi) streaming! I do miss binaural streaming, which isn’t a possibility as far as I am aware, since I am wearing two different devices now (Sentio plus hearing aid). If I need/want binaural streaming, I switch to my headphones, no biggie.

I used to be so worried about infections and making sure my left ear was dry, on top of being annoyed at having something in the left ear. So, most of the time, I would take my hearing aids out when I got home from work. My sweet husband never complained, even if I was complaining that I couldn’t hear due to taking out my own hearing aids, ha-ha! Now, when I am home, the Sentio 1 Mini processor stays on and the hearing aid in my right ear doesn’t bother me, so I am more present and need him to repeat things much less frequently.

My colleagues, after having to deal with me for a solid month of infection and healing, were incredibly relieved when I was fit. An unintended benefit, since I am more aware, is that I am much less jumpy/startled less often by people outside my peripheral vision or behind me. One of my other physicians used to think it was a fun game to sneak up behind me and surprise me—but no more, Dr. Mixson! You have been defeated by the incredible Sentio technology!

I have been pleasantly surprised by how well the processor stays firmly magnetized during walks outside in the southern heat, during Pilates, and in yoga—even when I am in crazy positions! I have only heard feedback once when in a yoga position where my arm was tucked right by my processor, but my friend next to me said she didn’t hear it at all.

I used to have a lot of anxiety and stress due to my frustration over being historically unable to understand speech in certain environments. In the short time we have been together, the Sentio System has been amazing. It makes me feel confident in those situations: being able to hear from which direction traffic noise is coming, my friends walking behind me, and in crowded restaurants—it has brought me a lot of peace. If I start to spiral at particular recommendations for Happy Hour, I must remind myself that I might not have been to that particular restaurant since I activated my Sentio, and so maybe I will do better this time. About 99 percent of the time, I am correct (some places just have terrible acoustics)!

Because the sound quality is quite different from my hearing aid, I used my audiology knowledge and figured out that, similar to cochlear implants, there may be some listening practice involved. Over a few weekends, when at home with my husband, I wore just my Sentio to let my brain adjust to the new sound. Since sound is being transmitted differently than I have experienced in the past, it’s just different! I waited two weeks after my initial fitting before making any adjustments to the settings, which is the same timeframe I request my hearing aid patients wait while trying to adjust to new sound. It has been one month (as of this writing) since my fitting and unsurprisingly, things now sound completely normal. Amazing what can happen when you follow your own advice!
