“…A survival analysis will be conducted based on surgical questionnaires to map out potential complications that may arise, the associated time course and frequency of occurrence. Other measures to be compared to the literature will be patient satisfaction, benefit and quality of life [ 4 , 7 , 18 ], soundfield hearing thresholds [ 2 , 4 , 11 ] and speech perception [ 2 , 4 , 11 ]. Changes in surgical practice that have occurred over time will be considered in the review to determine the impact that these may have had on performance.…”

BackgroundThe Vibrant Soundbridge middle ear implant and the Bonebridge bone conducting hearing device are hearing implants that use radio frequency transmission to send information from the sound processor to the internal transducer. This reduces the risk of skin problems and infection but requires a more involved surgical procedure than competitor skin penetrating devices. It is not known whether more complex surgery will lead to additional complications. There is little information available on the reliability of these systems and adverse medical or surgical events. The primary research question is to determine the reliability and complication rate for the Vibrant Soundbridge and Bonebridge. The secondary research question explores changes in quality of life following implantation of the devices. The tertiary research question looks at effectiveness via changes in auditory performance.MethodThe study was designed based on a combination of a literature search, two clinician focus groups and expert review.A multi-centre longitudinal observational study was designed. There are three study groups, two will have been implanted prior to the start of the study and one group, the prospective group, will be implanted after initiation of the study. Outcomes are surgical questionnaires, measures of quality of life, user satisfaction and speech perception tests in quiet and in noise.ConclusionThis is the first multi-centre study to look at these interventions and includes follow up over time to understand effectiveness, reliability, quality of life and complications.

“…Atas et al (24) presented quality-of-life questionnaire results on the same group of patients, with the subjects reporting statistically significant satisfaction with their AMEI. Mojallal et al (25) compared postoperative audiological data of patients with bone conduction devices to those implanted with the AMEI at the RW, and found that the AMEI-RW treatment delivered better results when the preoperative BC thresholds were closer to the range of 35 to 50 dB HL.…”

Objective:To report on the safety and efficacy of an investigational active middle ear implant (AMEI) in Japan, and to compare results to preoperative results with a hearing aid.Design:Prospective study conducted in Japan in which 23 Japanese-speaking adults suffering from conductive or mixed hearing loss received a VIBRANT SOUNDBRIDGE with implantation at the round window. Postoperative thresholds, speech perception results (word recognition scores, speech reception thresholds, signal-to-noise ratio [SNR]), and quality of life questionnaires at 20 weeks were compared with preoperative results with all patients receiving the same, best available hearing aid (HA).Results:Statistically significant improvements in postoperative AMEI-aided thresholds (1, 2, 4, and 8 kHz) and on the speech reception thresholds and word recognition scores tests, compared with preoperative HA-aided results, were observed. On the SNR, the subjects’ mean values showed statistically significant improvement, with −5.7 dB SNR for the AMEI-aided mean and −2.1 dB SNR for the preoperative HA-assisted mean. The APHAB quality of life questionnaire also showed statistically significant improvement with the AMEI.Conclusion:Results with the AMEI applied to the round window exceeded those of the best available hearing aid in speech perception as well as quality of life questionnaires. There were minimal adverse events or changes to patients’ residual hearing.

“…32,33 Treatment with round window vibroplasty leads to better hearing performance than treatment with a bone-anchored hearing device, if the bone conduction puretone average (0.5-4 kHz) is poorer than 35 dB HL. 34 A Jahrsdoerfer score of 4 or higher is recommended to consider a patient for implantation of an active middle ear implant and at least the round window should be accessible. 2 There have been successful implantations reported 35 for patients with Jahrsdoerfer score 3.…”

Surgical and Technical Modalities for Hearing Restoration in Ear Malformations

Malformations of the external and middle ear often go along with an aesthetic and functional handicap. Independent of additional aesthetic procedures, a successful functional hearing restoration leads to a tremendous gain in quality of life for affected patients. The introduction of implantable hearing systems (bone conduction and middle ear devices) offers new therapeutic options in this field. We focus on functional rehabilitation of patients with malformations, either by surgical reconstruction or the use of different implantable hearing devices, depending on the disease itself and the severity of malformation as well as hearing impairment. Patients with an open ear canal and minor malformations are good candidates for surgical hearing restoration of middle ear structures with passive titanium or autologous implants. In cases with complete fibrous or bony atresia of the ear canal, the most promising functional outcome and gain in quality of life can be expected with an active middle ear implant or a bone conduction device combined with a surgical aesthetic rehabilitation in a single or multi-step procedure. Although the surgical procedure for bone conduction devices is straightforward and safe, more sophisticated operations for active middle ear implants (e.g., Vibrant Soundbridge, MED-EL, Innsbruck, Austria) provide an improved speech discrimination in noise and the ability of sound localization compared with bone conduction devices where the stimulation reaches both cochleae.
