摘要
Objectives: To evaluate the safety and efficacy of auricle reconstruction and active transcutaneous bone conduction implantation in patients with bilateral microtia-atresia. Design: Patients were chosen prospectively, with each being his/her own control. Setting: The setting was a tertiary referral center. Participants: Twelve 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 measures: Patient 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). Results: All 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. Conclusions: The surgical procedure involving auricle reconstruction and Bonebridge implantation was safe and effective for patients with bilateral microtia-atresia, solving both appearance and hearing problems.
