Auditory and speech performance in patients following transcutaneous Osia®2 system implantation

The aim of the study was to prospectively evaluate the clinical audiological outcomes as well as patient satisfaction following implantation with the Osia^®2 System.

This is a prospective clinical study was conducted at high volume academic center of patients who underwent implantation of the Cochlear Osia^®2 System. Audiological outcomes included pre- and post-operative assessments of pure-tone audiometry, speech discrimination scores, and self-reported hearing difficulties questionnaire.

The surgical procedure and subsequent healing process proceeded without complications. We observed statistically significant improvements in audibility and speech understanding with the test device, compared to pre-operative conditions. The average gain across frequencies from 0.25 to 6 kHz was 39.17 db. Speech discrimination scores also showed an increase in scores' average from 64 ± 8 pre-operatively to 100 ± 8 post-operatively (p < .001). Additionally, the number of hearing issues assessed by the APHAB scale in various acoustic environments showed a statically significant decrease postoperative. The Global Score improved from 68.2 ± 5.53 pre-operatively to 27.3 ± 4.26 post-operatively.

The Osia^®2 System proves to be a safe and effective alternative for hearing rehabilitation in patients with conductive hearing loss (CHL), mixed hearing loss (MHL), or single-sided deafness (SSD).
