ObjectivesTo evaluate the safety and efficacy of auricle reconstruction and active transcutaneous bone-conduction implantation in patients with bilateral microtia-atresia.DesignPatients were chosen prospectively, with each being his/her own control.SettingThe setting was a tertiary referral center.ParticipantsTwelve patients, aged 6–18 years, with bilateral microtia-atresia suffering from bilateral conductive hearing loss. All had an upper bone conduction threshold limit of 45 dB HL at frequencies of 0.5–4 kHz.Main outcome measuresPatient satisfaction with the reconstructed auricle was rated as highly satisfactory, basically satisfactory, or unsatisfactory. Mean pure-tone thresholds and speech audiometry test results were compared among patients unaided, with a soft-band Bonebridge, and with an implanted Bonebridge. Subjective satisfaction was analyzed using three questionnaires: the Abbreviated Profile of Hearing Aid Benefit (APHAB), the Glasgow children's benefit inventory (GCBI), and the International Outcome Inventory for Hearing Aids (IOI-HA).ResultsAll patients who underwent auricle reconstruction expressed satisfaction with their appearance. The mean pure-tone thresholds of unaided patients and those with soft-band and implanted Bonebridge were 55.25 ± 3.43 dBHL, 31.37 ± 3.03 dBHL, and 21.25 ± 2.16 dBHL, respectively. The mean speech discrimination scores measured in a sound field with a presentation level of 65 dB SPL under these three conditions were 46.0 ± 0.11%, 80.0 ± 0.09%, and 94.0 ± 0.02%, respectively. Questionnaires demonstrated patients' benefits and satisfaction with this surgery.ConclusionsThe surgical procedure involving auricle reconstruction and Bonebridge implantation was safe and effective for patients with bilateral microtia-atresia, solving both appearance and hearing problems.
