Bone anchored hearing aid o Anotia no ear describes a rare, congenital deformity, that involves the complete absence of the pinna, the outer projected portion of the ear, and narrowing or absence of the ear canal,o A bone-anchored hearing aid is an implantable device that allows the listener to hear by bone conduction without the inconvenience of a traditional bone conduction hearing aid. Its more comfortable, and the sound quality is better, partly because the device stays in place.o Unlike a middle ear implant, which requires a normally functioning middle ear, this type of hearing aid is typically used by listeners who have conductive or mixed hearing loss. Bone conduction hearing aids have traditionally been used by people bom without ear canals or with small, misshapen ears that cant support conventional hearing aids, or by people who have chronic middle ear disease thats aggravated by wearing a hearing aid or earmold in the ear canal for example, people with draining ears.
