Abstract:Speech performance is nearly normal in both quiet and noise conditions. The surgery did not affect the tissues that are important for the later ear reconstruction.
“…Frenzel et al [11] published a mean functional gain of 45.5 dB in seven patients. This same group recently published a case of a 6-year-old implanted patient with normal hearing thresholds after implantation of VSB [12]. Our experience supports the published data [7].…”
The mean functional gain obtained for all patients evaluated was 62 dB at 0.5 kHz, 60 dB at 1 kHz, 48.3 dB at 2 kHz, and 50.8 dB at 4 kHz. The mean functional gain for all frequencies evaluated was 55.1 dB.

“…Ultimately, preventing soft tissue problems seen with Baha 1 at the soft tissue implant interface may require a fully implantable hearing device such as the Vibrant Soundbridge 1 or Sophono Otomag 1 device or an intraoral bone-conduction device recently reported by Popelka et al [16,17].…”
“…We have implanted the device in infants who are 12 to 15 months of age. This allows reasonable stimulation of both cochleae separately to achieve more natural maturation of the auditory pathways before the age of 2 (25,26) With the incision line 15 to 20 mm posterior to the anticipated position of the auricle, followed by a subperiosteal preparation toward the atretic plane, the conservation of delicate tissues for plastic reconstruction is not problematic (9).…”
Active middle ear implants allow early and selective stimulation of the auditory pathway in children with congenital conductive hearing loss and are expected to lead to the normal development of the binaural hearing functions. To date, it is the only option if the stimulation is to be started at the age of 12 to 18 months. This was implemented into a new flowchart for aural atresia-microtia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
