Abstract:
This article discusses the Envoy Esteem implantable hearing system, a completely implantable hearing device. The device is indicated for patients older than 18 years with stable moderate to severe sensorineural hearing loss and good speech discrimination. The device is placed through an intact canal wall tympanomastoidectomy with a wide facial recess approach. The implant is typically activated at 6 to 8 weeks postoperatively and usually requires several adjustments for optimal performance. The sound processor/battery lasts 4.5 to 9.0 years and can be replaced through a minor outpatient procedure.
