Popis: Objective The active transcutaneous bone conduction implant Bonebridge®, is indicated for patients affected by bilateral conductive/mixed hearing loss or unilateral sensorineural hearing loss, showing hearing outcomes similar to other percutaneous bone conduction implants, but with a lower rate of complications. The aim of this study was to analyse the hearing outcomes in a series of 26 patients affected by conductive or mixed hearing loss and treated with Bonebridge®. Methods 26 of 30 patients implanted with Bonebridge® between October 2012 and May 2017, were included in the study. We compared the air conduction thresholds at the frequencies 500, 1000, 2000, 3000, 4000 Hz, the SRT 50% and the percentage of correct answers at an intensity of 50 dB with and without the implant. Results “Pure tone average” with the implant was 34.91 dB showing an average gain of 33.46 dB. Average SRT 50% with the implant was 34.33 dB, whereas before the surgery no patient achieved 50% of correct answers at a sound intensity of 50 dB. The percentage of correct answers at 50 dB changed from 11% without the implant to 85% with it. We only observed one complication consisting of an extrusion of the implant in a patient with a history of 2 previous rhytidectomies. Conclusions The hearing outcomes obtained in our study are similar to those published in the literature. Bonebridge® represents an excellent alternative in the treatment of conductive or mixed hearing loss, and with a lower rate of complications.
