“…Additionally, individuals with SSD can also be BCI candidates if traditional air conduction amplification or contralateral routing of sound (CROS) hearing aids are ineffective. [13][14][15][16][17] In this population, the sound signal is transmitted to the contralateral, functional cochlea, though it is noteworthy that this mechanism does not recreate binaural hearing.…”

“…13 Specifically in patients with MHL and a more severe SNHL, the percutaneous implant may be more appropriate to overcome the soft tissue attenuation, particularly in the high frequencies. 16,17 There are disadvantages to the percutaneous systems, which are largely consist of cosmetic concerns and skin complications around the implant, which can include skin overgrowth, chronic wound infection, implant extrusion, and loss due to trauma. Most of the literature on this subject has identified soft tissue reactions to the protruding titanium skin-piercing coupler to be the most common complication of a percutaneous BCI.…”

Bone Conduction Implants for Hearing Rehabilitation in Skull Base Tumor Patients

Bone conduction implants transfer sound to the inner ear through direct vibration of the skull. In patients with skull base tumors and infections, these devices can bypass a dysfunctional ear canal and/or middle ear. Though not all skull base surgery patients opt for bone conduction hearing rehabilitation, a variety of these devices have been developed and marketed over time. This article reviews the evolution and existing state of bone conduction technology.

“…Since the successful placement of the first implant was reported in 1977, more than 10,000 patients worldwide have received BCIs [1]. In addition, conventional bone conduction hearing aids, such as the soft Headband, are a gold standard for preoperative evaluation in young patients who cannot undergo implantation and are used as a good method for hearing rehabilitation in patients refusing surgery [4,5].…”

Background and Objectives: We aimed to measure the head dimensions on computed tomography (CT) images, to compare them to directly measured head dimensions, and to predict a new parameter of bone thickness for aiding bone conduction implant (BCI) placement. Subjects and Methods: We reviewed the facial and mandibular bone CT images of 406 patients. Their head sizes were analyzed using five parameters included in the 6th Size Korea project, and they were divided into age groups (ranging from the 10s to the 80s). We compared the head length, head width, sagittal arc, bitragion arc, and head circumference in the CT and Size Korea groups. We also added the parameter bone thickness for aiding BCI placement. Results: All the head size parameters measured using CT were significantly smaller than those measured directly, with head length showing the smallest difference at 7.85 mm. The differences in the other four parameters between the two groups according to patient age were not statistically significantly different. Bone thickness had the highest value of 4.89±0.93 mm in the 70s and the lowest value of 4.10±0.99 mm in the 10s. Bone thickness also significantly correlated with head width (p=0.038). Conclusions: Our findings suggested that the CT and direct measurements yielded consistent data. Moreover, CT enabled the measurement of bone sizes, including bone thickness, that are impossible to measure directly. CT measurements may complement direct measurements in the Size Korea data when used for developing bone conduction hearing devices (BCIs and headsets) for the Korean population.

Introduction The BAHA (bone-anchored hearing aid) Attract is a magnetic transcutaneous bone conduction device anchored into the temporal bone. The standard surgical technique for BAHA Attract is a multi-tools time-consuming process, which requires a large cutaneous incision. The objective of this study is to describe and test the feasibility of a minimally invasive pocket (MIP) technique for Magnet Bone Implant Hearing Aid (MBIHA) with a modified magnet of BAHA Attract without fixation and without any tissue reduction. We use a 3-cm vertical skin incision and a subperiosteal pocket. Method A study of 10 patients with conductive or mixed hearing loss who benefited from a MBIHA using the MIP technique is presented. The pure tone average (PTA) (dB) for air-conduction thresholds and the speech recognition threshold (SRT) (dB) in speech audiometry in quiet are calculated. The Entific Medical Systems (EMS) questionnaire and the postoperative clinical outcomes are realized. Results We found a significant improvement of 33.8 dB on average for the PTA and 44.8 dB for the SRT with MBIHA at 3 months, compared with unaided situation. No implant was removed or displaced after 2 years of follow-up. The skin condition remains intact in all the cases. Conclusion The minimally subperiosteal pocket surgical technique MIP without fixation and with tissue preservation for the MBIHA is safe, rapid and effective for patients with conductive or mixed hearing loss. It opens new perspectives of development and modify conventional concept in magnetic coupling of bone-conducted device.
