Abstract

Objective

Investigation of the long-term performance and safety of Bonebridge in children and adolescents with congenital bilateral conductive hearing loss (BCHL) over 3 years post-implantation.

Methods

20 children and adolescents diagnosed with congenital BCHL underwent Bonebridge implantation over 36 months were enrolled. Preoperative and final follow-up pure-tone average (PTA) results were recorded, and whether postoperative complications occurred. All patients tested under two listening conditions: (1) unaided, (2) Bonebridge aided. The speech reception thresholds (SRTs), speech discrimination scores (SDSs) and sound field hearing thresholds (SFHTs) were measured. The mean absolute error (MAE) of sound source localization was calculated to assess the sound localization accuracy.

Results

The median age of 20 patients underwent Bonebridge implantation was 9 years old, and follow-up time was 55 months. There were no difference in PTA air conduction and bone conduction between preoperative with postoperative. The performance in SRTs, SDSs and SFHTs were significantly higher in the Bonebridge aided condition than that in the unaided. Concerning sound source localization, the accuracy of localization exhibited a sharp decline when using a single side Bonebridge. However, their sound localization abilities on the Bonebridge implantation same side remained unaffected. One patient had implant exposure, and completed the experiment with the exposed Bonebridge, then underwent a revision surgery. All other complications were resolved by conservative treatment.

Conclusion

The performance and safety of Bonebridge were established in children and adolescents with congenital BCHL over 3 years post-implantation.

期刊介绍： The international journal Auris Nasus Larynx provides the opportunity for rapid, carefully reviewed publications concerning the fundamental and clinical aspects of otorhinolaryngology and related fields. This includes otology, neurotology, bronchoesophagology, laryngology, rhinology, allergology, head and neck medicine and oncologic surgery, maxillofacial and plastic surgery, audiology, speech science. Original papers, short communications and original case reports can be submitted. Reviews on recent developments are invited regularly and Letters to the Editor commenting on papers or any aspect of Auris Nasus Larynx are welcomed. Founded in 1973 and previously published by the Society for Promotion of International Otorhinolaryngology, the journal is now the official English-language journal of the Oto-Rhino-Laryngological Society of Japan, Inc. The aim of its new international Editorial Board is to make Auris Nasus Larynx an international forum for high quality research and clinical sciences.
