- Abstract
Objectives: The Bonebridge system is indicated for the treatment of patients with conductive or mixed hearing loss, whose BC (Bone Conduction) thresholds are not higher than 45 dB HL for 500, 1000, 2000, 4000 Hz in the ear to be implanted. The aim of this study is to measure self-assessed quality of life in adult patients implanted with the Bonebridge system. The secondary objective is to confirm the device's effectiveness in hearing in a population suffering from mixed or conductive hearing loss. Material and methods: The adult patients with mixed or conductive hearing loss were implanted unilaterally with the Bonebridge system in the World Hearing Center in Kajetany. The Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire was used to measure patient-reported quality of life before intervention and at 3 and 6 months after activation of the device. At the same timeframes, puretone audiometry and speech audiometry in quiet and in noise were performed. Results: Hearing-specific quality of life increased significantly after intervention and remained stable up to 6 months. The mean functional gain after 6 months of device use was 28 dB. Both word recognition in quiet and speech reception threshold in noise were significantly better after 6 months compared to before surgery. Outcomes of aided speech understanding were independent of initial boneconduction thresholds and equally high. Conclusions: Our results show a significant improvement in quality of life with the Bonebridge up to 6 months after activation. Furthermore, the Bonebridge provides significant audiological benefit for patients suffering from mixed and conductive hearing loss in both speech understanding in quiet and in noise. Together with a very low rate and minor nature of adverse events, it is a good solution for hearing rehabilitation in patients with mixed or conductive hearing loss up to a bone conduction threshold of 45 dB HL.
