![]() ![]() Vivien Williams: If hearing aids don't work for you, cochlear implants might. For the Mayo Clinic News Network, I'm Vivien Williams. Vivien Williams: For Aida to be able to hear the happy sounds of childhood. Matt Little: Just to be able to hear, - hear the sounds around her - that's what I'm looking forward to. Melissa DeJong, Au.D.: For me, it's what brings me to work every day. Vivien Williams: To people in that room, witnessing Aida hear for the first time was to witness a miracle. Aida's brother, parents, grandparents and cousins were all there the day audiologists at Mayo Clinic attached the outside piece behind Aida's ear and turned it on for the first time. Vivien Williams: Cochlear implants work for most people who have them, but there's always the chance they won't. to activate it, they'll just have the outer piece attached, and then it's just like, basically, from what I understand, like a Bluetooth headset, pretty much. Vivien Williams: The device sends a tiny current via the electrodes to the cochlea and then to the brain. And the electrodes are connected to a device that's underneath the skin in the scalp. Carlson: …slip a small group of electrodes or wires that are all kind of bundled together, and they follow the natural curvature of the cochlea. Baby Aida, like all patients who get cochlear implants, went through two steps. ![]() A cochlear implant bypasses the missing hair cells. The sound waves then move into the inner ear, or cochlea, where tiny hair cells turn them into electrical signals that are transmitted to the brain. The soundwaves cause the ear drum and middle ear bones to vibrate. The outer ear collects sound, which travels down the ear canal to the ear drum. Vivien Williams: Here are the basics on how hearing works. Carlson: There's a lot of different changes that happen in the inner ear that result in this hearing loss, but the end result is loss of inner ear hair cells for almost all these different conditions. Matthew Carlson is also on Aida's care team.ĭr. Matthew Carlson, M.D.: Cochlear implant surgery and cochlear implant technology has evolved very significantly over the last several decades. Vivien Williams: But, unlike these fish, Aida may benefit from technology to help her hear. Schimmenti: We share 70 percent of our genome with zebrafish, and the same genes that cause conditions in us, cause the same condition in fish. Schimmenti uses to learn about deafness similar to Aida's are tanks full of zebra fish.ĭr. Schimmenti: If you went and Googled this disorder, you'll see pictures of people who may have a white streak of hair, or they may have one blue eye and one brown eye…well, this the fish lab. Lisa Schimmenti says Waardenburg syndrome is a collection of symptoms caused by a change in a gene.ĭr. Lisa Schimmenti, M.D.: Aida has a condition called Waardenburg syndrome. Vivien Williams: Aida's mom and dad, Melinda and Matt Little, took her to Mayo Clinic, where a team of experts diagnosed Aida with a rare genetic condition. Melinda Little: When you first hear it, you kind of say, "That's not true,' or, 'What can we do to help it?" Vivien Williams: Baby Aida can't hear any of it. Vivien Williams: The happy sounds of childhood, a brother's giggle, a mother's loving coo or the joy of your own calls of contentment.
