The hospital recently implanted a bone-anchored hearing aid (BAHA) in a 4-year-old, 9-month-old child. The child suffered from congenital atresia, severe middle ear malformation, poor hearing, slurred speech, and inability to communicate normally, which affected his learning. After the BAHA soft band test, the child was implanted with near-normal hearing. BAHA is a hearing aid that improves hearing through the only direct bone conduction method. Due to its superior performance and simple implantation, BAHA has provided hearing support to more than 100,000 patients around the world, making it an alternative to hearing aids, middle ear implants, and cochlear implants for restoring hearing to deaf patients. At present, the Department of Otorhinolaryngology-Head and Neck Surgery of our hospital is one of the few centers in China that can carry out the above hearing rehabilitation and surgery according to the patient’s hearing condition. It is reported that this child is the youngest person in China to be implanted with BAHA, which is indicated for patients with bilateral conductive or mixed deafness, unilateral conductive deafness or mixed deafness, unilateral sensorineural deafness, and conductive or mixed deafness with moderate mental retardation.
