Not long ago, we came across a child who had been unable to hear outside sounds due to a congenital microtia at work. The child’s parents anxiously ran to many hospitals, but because the child was born without an external ear canal, he could not wear a conventional in-ear hearing aid. Until recently, with the introduction and application of a bone anchored hearing device in China, this child’s deaf fate was changed. Bone anchored hearing devices do not require the transmission of sound from the external ear canal, but rather the transmission of acoustic vibrations through the skull, which directly stimulates the nerve structures that sense sound, thus creating the sense of hearing. This technology has been used abroad for 30 years and has more than 100,000 users worldwide. Bone anchored hearing devices are not only suitable for patients with small ear deformities, but also for patients with chronic otitis media, various conductive deafness, and some elderly deafness and neurological deafness with total deafness in one ear.
