Introduction: The transcutaneous bone conduction auditory implant Bonebridge is a new semi-implantable
device indicated for conductive and/or mixed hearing loss (C/MHL), or single sided deafness (SSD).
Objective: To evaluate the surgical outcomes, auditory benefits, quality of life and patient satisfaction scores in
conductive, mixed hearing loss and single sided deafness, in patients implanted with the Bonebridge system.
Methods: Prospective study on patients with C/MHL, or SSD. The auditory outcomes, quality of life outcomes,
and satisfaction scores with the device will be assessed.
Results: 24 patients have been implanted, including 12 males and 12 females. Fifteen of those cases were
placed in the sinodural angle and 9 in the retrosigmoid region. Twelve patients received the device for C/MHL
and 12 for SSD. C/MHL patients showed a statistical significant (p< 0.04) mean gains of 25.8 and 26 dB in PTA
at 1 and 3 months after surgery, respectively. SSD patients also showed a significant (p< 0.03) mean gains of
60.2 and 77.1 dB at 1 and 3 months after surgery, respectively. Positive indicators were obtained in general
satisfaction with the device, as well as significant improvement (p< 0.05) in the speech perception, sound
localization and quality of sound, compared to their pre-op status. Benefits in their general health and quality of
life were reported too.
Conclusions: The active transcutaneous active bone conduction auditory implant gives significant auditory gain
to patients with C/MHL and SSD. Patients report high satisfaction with the implant with improvements in their
auditory gains, general health and quality of life.
