入选标准
- •Adults, 18 years of age or older at the time of implantation
- •Conductive or mixed hearing loss, defined as:
- •Conductive hearing loss with pure-tone average (PTA) for bone conduction thresholds better than or equal to 25 dB at 500, 1000, 2000 and 3000 Hz
- •Mixed hearing loss with PTA for bone conduction thresholds better than or equal to 45dB at 500, 1000, 2000, and 3000 Hz
- •Air-bone gap greater than or equal to 30 dB at 500, 1000, 2000, and 3000 Hz
- •Ability to benefit from amplification as defined by a monosyllabic (CNC) word score of 30% correct or better
- •Bilateral BONEBRIDGE can be considered if the difference in PTA for bone conduction thresholds is 10 dB or less between the right and left ears
- •Prior experience with acoustic or bone conduction hearing aids, unless candidate is unable to wear amplification for medical reasons
- •Able to complete testing materials in English
- •CT scan indicating the patient's anatomy is adequate to enable placement of the implant
- •Ability to undergo general anesthesia
- •Appropriate motivation and expectation levels
- •Stated willingness to comply with all study procedures for the duration of the study
排除标准
- •Evidence that hearing loss is retrocochlear in origin
- •Skin or scalp condition precluding use of external audio processor
- •Suspected cognitive impairment or organic brain dysfunction
