OBJECTIVE: To evaluate the long-term safety, efficacy, and satisfaction of Bonebridge implantation in children under 12 years.
METHODS: This retrospective study followed 34 patients (aged 5.4-11.8 years) who underwent Bonebridge implantation between 2016 and 2020, with a median follow-up of 55 months. Audiological outcomes, including pure-tone audiometry (PTA), speech reception thresholds (SRTs), speech discrimination scores (SDSs), and sound field hearing thresholds (SFHTs) were assessed. Adverse events and patient-reported satisfaction (HDSS) were recorded.
RESULTS: Bonebridge significantly improved speech perception (SRT: -6.20 dB in unilateral; -0.18 dB in bilateral) and SFHT (mean improvement: 20.80 dB unilateral; 29.07 dB bilateral). SDS for monosyllables, disyllables, and sentences showed substantial gains in aided conditions. Adverse events were mild to moderate, except for one serious device failure resolved with revision surgery. Sound localization accuracy decreased in patients with bilateral hearing loss who used a unilateral Bonebridge due to unilateral auditory stimulation. Patient satisfaction was high, with bilateral hearing loss reporting longer daily usage.
CONCLUSION: Bonebridge is a safe and effective intervention for young children under 12 years with conductive hearing loss, enhancing auditory access and quality of life.
