Bridging Continents Through Sound
Earlier this year, Oticon Medical Marketing Manager and audiologist, Hilary McManus, had the opportunity to travel to Malawi with Hearing the Call, a nonprofit organization that focuses not on short-term relief, but on the long-term development of sustainable hearing healthcare in the communities it serves. Rather than providing one-time care and moving on, Hearing the Call collaborates with local professionals to build lasting systems through education, training, and access to resources.

This model of development over relief is backed by growing global health research. Short-term missions can sometimes unintentionally undermine local providers, disrupt continuity of care, and create dependency. Sustainable development, on the other hand, strengthens local infrastructure, empowers communities, and ensures that care continues long after international teams depart.1.2.3.4.
In Malawi, Hilary saw firsthand the vital role local providers play in ensuring that care is both sustainable and culturally responsive. These providers bring invaluable insights into their communities, enhancing the quality and relevance of the care delivered.

During three clinical days, Hilary’s group saw 174 patients, which included 113 traditional hearing aid fittings and eight Ponto™ fittings. They were also able to provide training to local audiologists and audiology students to ensure these patients receive top-tier follow-up care.
It was a whirlwind of activity, but what stood out most was the collaboration with dedicated Malawian clinicians and students, whose commitment to their patients and profession is nothing short of inspiring. Hilary’s group tried to see as many patients as possible while still providing excellent care. Even in this fast-paced environment, every individual on the team was able to not only teach, but learn from clinicians, students, and patients.
One of the audiologists on the trip asked everyone to think of one word to describe their time in Malawi and the first word that popped into Hilary’s mind was laughter. “Of course, we all worked hard giving those who attended the outreach clinics the best possible care,” Hilary shared. “But what I remember most are the moments of shared laughter between team members, with patients, and with my Malawian colleagues. It was the kind of laughter that supersedes language barriers, eases the weight of long days, and reminds you why you chose this profession in the first place.”
Despite the high prevalence of otitis media (an infection of the middle ear) and associated hearing loss, few Malawians have ever received a hearing device. Misconceptions about hearing loss and ear infections, combined with limited access to care with widespread use of home remedies, highlight critical gaps in hearing health literacy and service delivery. Bone anchored hearing systems like Ponto are uniquely suited to these communities, where conductive hearing loss and middle ear conditions are extremely common.
A Note from Yamikani Dumbo, Local Malawi Audiologist
Malawi faces significant challenges in addressing hearing loss due to limited resources. There is only one institution offering an Audiology degree, making it difficult for aspiring audiologists to access education and training. Consequently, the country lacks sufficient audiologists to provide essential services. Those who do qualify often seek job opportunities abroad, leaving Malawi with a severe shortage of skilled professionals.

Although four government hospitals offer audiology services, access to care remains insufficient due to limited equipment and resources. Furthermore, the absence of hearing aids at these hospitals limits the effectiveness of hearing loss diagnoses. This lack of services and essential tools deepens the problem, leaving many individuals without access to the care they need.
The state of audiology in Malawi is concerning and requires attention. There is a need to raise awareness through educating the public about the importance of ear health and the consequences of untreated hearing loss. Increasing accessibility in audiology education and training opportunities to increase the number of skilled professionals is needed to minimize challenges in accessing care. It is also essential to improve local audiology services by providing appropriate equipment and resources so they can offer comprehensive care.

There are two main types of systems. The first is considered passive; this uses desiccant, much like the packs that you find in vitamin bottles. These are typically called, “jar dryers” and contain the desiccant beads that can be “recharged” by putting them in the oven or microwave. You simply put the processor in the jar without a battery and close the lid. Jar dryers are great for travel, camping or when you do not want to use electricity.
The second type is an active dehumidifier. This type also has a desiccant pack or puck but adds in a fan to circulate air. These “box dryer” systems can also have a UV-C light that acts as a germicide. Box dryers more aggressively reduce moisture from your Ponto processor. Again, you can put your processor in the dryer without a battery and turn the dryer on. The box dryer will typically run through a cycle that lasts between 6-8 hours. You can feel comfortable using these types of drying systems every night and as your storage case overnight.
After my first medical mission trip to Guatemala in 2020, I came back to the states with a global pandemic starting and a constellation of symptoms that seemed to be getting worse that my doctor could not explain. It would not be until January of 2021 that I would learn a small brain tumor was responsible for my debilitating symptoms.
My work in the NICU involves caring for the most vulnerable of all patients. Some weigh only 600g! A mistake can be devastating. I need to be able to hear the orders from providers, the heartbeat and lung sounds of my patients, and communicate with parents efficiently.
I have to put surgical caps on to enter surgical suites, and the small size helps make this process a lot easier. I use the OpenSound Navigator™ feature a lot in the loud NICU especially when I am working the night shift. When I get tired, it is harder to sort out sounds, and this really helps during those times.
It took almost two months, but I remember one day actually forgetting that I had my Ponto 5 Mini on and that I was deaf on one side. Something had clicked. Earlier, I had told the organizer of the medical mission trips that I would not be able to go this year because I was not sure I could help anyone due to my hearing loss. After that day though, I called him up and said, “Sign me up, I’m ready.” I have now completed my second medical mission trip to Guatemala personally helping hundreds of patients—none of whom had a clue that I once struggled with hearing.

Bone conduction hearing devices are designed to treat
I’m scheduled to get bilateral Ponto 4s programmed for trial Wednesday. In the meantime, I love teaching people! I’m working with the company that set up our phone system to come up with a solution to resolve my difficulty with phone usage. I had quite the conversation explaining the bone anchored hearing system and the Bluetooth® direct connection capabilities of the new Ponto 4. The person I spoke to was fascinated, to say the least! I consider it a win-win: I’ve educated more people about hearing loss and the technology to aid those of us who have it, plus I resolved my phone issue.
The Ponto 4s are so small and lightweight that it feels as if they aren’t even attached. I do miss the ability to mute from the processor itself but using the Oticon ON™ app is no different than using the app with my hearing aid. The direct Bluetooth is absolutely wonderful, except I can only use it in private. As with the streamer, everyone else around me can hear sounds traveling through the processors. At least my coworkers are used to me being in my office with my door closed.
