| Summary: | Objectives: To investigate the surgical and audiological
outcome of Bonebridge (BB) at tertiary centres in Malaysia.
Study Design: Prospective, intra-subject repeated
measurements of which each subject is his/her own control,
from year 2012 to 2016 at two tertiary referral centres.
Methods: Twenty patients with hearing loss who fulfilled
criteria for BB and showed good response to bone
conduction hearing aid trial were included. Implantations of
BB were carried out under general anaesthesia with preoperative computed tomography (CT) planning.
Complications were monitored up to six months
postoperatively. Subjects’ audiometric thresholds for air
conduction, bone conduction and sound field at frequencies
of 250Hz to 8kHz were assessed preoperatively and at six
months postoperatively. Subjects’ satisfaction was
evaluated at 6 months post operatively with Hearing Device
Satisfaction Scale (HDSS) questionnaire.
Results: There was no major complication reported. Mean
aided sound field thresholds showed significant
improvement for more than 30dB from 500 to 4000kHz
(p<0.05). There was no significant change in mean unaided
air conduction and bone conduction thresholds pre and post
operatively from 500 to 4000kHz, with a difference of less
than 5dB (p>0.05). All the patients were very satisfied (>80%)
with the implant, attributing to the promising functional
outcome and acceptable cosmetic appearance.
Conclusions: BB implantation surgery is safe and is
effective in restoring hearing deficits among patients aged
five and above with conductive or mixed hearing loss and
single-sided hearing loss |
