Summary
The Envoy Esteem is a fully implantable hearing device for adults with sensorineural hearing loss. This system offers a long-lasting solution, with the sound processor replaceable via an outpatient procedure.
Area of Science:
- Otolaryngology
- Biomedical Engineering
- Neuroscience
Background:
- Sensorineural hearing loss affects millions, with traditional hearing aids not always suitable.
- Implantable hearing systems offer an alternative for specific patient profiles.
- The Envoy Esteem represents a fully implantable option for hearing restoration.
Purpose of the Study:
- To describe the Envoy Esteem, a completely implantable hearing system.
- To outline the indications, surgical approach, and management of this device.
Main Methods:
- Surgical placement via intact canal wall tympanomastoidectomy with a wide facial recess approach.
- Postoperative activation at 6-8 weeks, followed by adjustments for optimal performance.
- Assessment of device longevity and replacement procedures.
Main Results:
- The device is indicated for adults (18+ years) with stable moderate to severe sensorineural hearing loss and good speech discrimination.
- Surgical approach detailed, with typical activation and adjustment periods noted.
- Sound processor/battery lifespan of 4.5 to 9.0 years, replaceable in an outpatient setting.
Conclusions:
- The Envoy Esteem provides a fully implantable hearing solution for selected patients.
- The surgical technique and postoperative management are crucial for optimal outcomes.
- The device offers a durable and manageable long-term hearing restoration option.
