“…It is known that bilateral symmetry of hearing implantable devices is directly related to cosmetic appearance. 5 Considering it, our results suggest that the use of the method proposed in this study employing the guide‐marker could improve cosmetic appearance of bilateral percutaneous BAHS users and therefore their effectiveness in daily life.…”

“…It is known that symmetry is an important goal in achieving successful in bilateral implantation of hearing devices, since it is directly related to the cosmetic appearance and patient's satisfaction with the device. 5 Zawawi et al 6 carried out a prospective cohort study of 100 consecutive new candidates to BAHS and found that the main reason for surgery refusal was cosmetic and social acceptance, even in those patients with satisfactory preoperative audiometric improvements with the device. Other study 7 also showed that up to 19% of patients implanted with BAHS consider that the device is less appealing socially and, one subject, reported that would not choose to have BAHS again due to his unsatisfaction with cosmetic appearance, although he was very satisfied overall with the device.…”

“…Hallwachs et al 5 proposed a method with the use of a mirror template to improve the bilateral symmetry in cochlear implant (CI) surgery. They found improved symmetry perceived by the patients, and high patient and family satisfaction regarding aesthetics, although they did not employ an objective tool to precisely investigate the bilateral symmetry.…”

ObjectivesTo investigate the use of a novel technique to estimate the symmetrical placement of percutaneous bone‐anchored hearing systems (BAHS) with a guide‐marker in patients undergoing bilateral surgery with this device.Study DesignProspective cohort study.MethodsA guide‐marker and anatomical landmarks were used to estimate the implant placement and transferred to the contralateral ear in 12 subjects eligible for bilateral BAHS surgery. To investigate the bilateral symmetry, preoperative tri‐dimensional (3D) computed tomography (CT) image reconstruction was used to compare the distances between the mandibular condyle and implant placement estimation (mandible‐implant distance) in both the right and left ears of the subjects.ResultsThe guide‐marker could be used to estimate the bilateral implant placement in all subjects included in this study, simply and easily, including one subject with craniofacial malformation. The mean mandible‐implant distances were 5.37 and 5.38 cm, in the right and left ears of the subjects, respectively, and no differences were observed between them, thereby indicating optimal bilateral symmetry.ConclusionThe use of the guide‐marker proved to be an effective tool to provide symmetrical placement of bilateral BAHS. We propose a novel method employing a simple guide‐marker and tracing based on symmetrical anatomical landmarks to achieve precise placement and optimal symmetry and which may be easily adopted in the surgical routine of BAHS.Level of Evidence3.
