Frequency-specific hearing studies are important for predicting hearing results and the prognosis after stapes surgery, to prepare for the rehabilitation of frequency-specific hearing in patients with otosclerosis. To evaluate outcomes of stapes surgery of Chinese otosclerosis patients with different degrees of hearing loss. We conducted a retrospective analysis of 213 otosclerosis patients who underwent stapes surgery in our hospital. Pre- and post-operative audiometric evaluation using conventional audiometry. The post-op ABG was less than 20 dB in 94.52% of all cases after surgery. There was no statistical significance of the post-op ABG among different groups at all frequencies except extremely severe group ( < .05). There was a significant improvement of both AC and BC thresholds in post-op period and the most significant improvement was found in severe group. There were no serious post-op complications and no re-operations during the follow-up period. Stapes surgery is a suitable treatment option for otosclerosis with mild to extremely severe HL. The mild to moderate hearing loss groups had the most significant improvement of AC thresholds in the low frequency region, and the severe to extremely severe groups appeared in the high frequency region.

Purpose: There are challenges in understanding the biomechanics of the human middle ear, and established methods for studying this system show significant limitations. In this study, we evaluate a novel dynamic imaging technique based on synchrotron X-ray microtomography designed to assess the biomechanical properties of the human middle ear by comparing it to laser-Doppler vibrometry (LDV).
Methods: We examined three fresh-frozen temporal bones (TB), two donated by white males and one by a Black female, using dynamic synchrotron-based X-ray microtomography for 256 and 512 Hz, stimulated at 110 dB and 120 dB sound pressure level (SPL).

Otosclerosis leads to stapes fixation and consequent conductive hearing loss. Surgery is the mainstay of treatment, and it can be achieved through small fenestra stapedotomy or stapedectomy. Despite the first being favored by most, evidence supporting its superiority over the latter remains inconclusive.

Objectives: Although various stapedotomy and stapedectomy techniques exist, anchoring the piston can be challenging. We present a novel surgical approach for treating congenital stapes malformations with an atypical facial nerve trajectory.
Methods: This is a case of a 7-year-old boy presenting with bilateral conductive hearing loss.
