Abstract:

The objective of this study is to evaluate stapes surgery in patients with otosclerosis and “profound” hearing loss. This means they meet hearing threshold criteria for cochlear implantation (CI). We performed a retrospective study and patient questionnaire. The results from 33 patients (35 ears) were recorded (mean age: 63.6, range: 40-85). The primary outcome measure was hearing thresholds recorded before and after surgery at 0.5, 1, 2, 3, and 4 kHz. Hearing thresholds at 2 and 4 kHz were also analyzed. Glasgow Benefit Inventory (GBI) was used in 21 patients to assess life quality changes. Hearing thresholds improved in 80% of ears (mean improvement, 26.3 dB), were unchanged in 11.4%, and worsened in 8.6%. Mean GBI score was +20.7. Hearing aid use decreased in 23.8% and ceased in 28.6%. One patient subsequently underwent CI. For patients with profound otosclerosis, stapes surgery provides a quantitative improvement in hearing thresholds and improvement in quality of life, with reduced reliance on hearing aids. This avoids CI, auditory rehabilitation, and a change in quality and tonality of sound
