BAHA(Bone Anchored Hearing Aid) 시술 경험

Abstract

For auditory rehabilitation in patients with hearing loss, air conduction hearing aids are primarily considered. However, when applying to patients with congenital atresia or chronic ear infection, limitations are expected and conventional bone conduction hearing aids may be used in these cases. Nevertheless, since bone conduction hearing aids also were found to have a number of drawbacks such as poor sound quality, high battery consumption, poor aesthetics, and headache by the pressure from the device against the skull, the bone anchored hearing aid (BAHA) has been introduced as an effective means to overcome such limitations. Whereas traditional bone conductors are transcutaneous and they works by exerting pressure against the skull, BAHA works percutaneously. Three cases of BAHA insertion surgery are presented along with the indications and surgical methods of BAHA surgery.
