Conclusion:
Every patient with severe or profound hearing loss must have a temporal bone high-resolution computed tomography (CT) scan. Stapedotomy is a simple, safe and low-cost procedure compared with cochlear implantation and can provide very good results. This can justify our decision to propose stapedotomy at the initial treatment in patients with very far-advanced otosclerosis. In cases of hearing failure after stapes surgery, cochlear implantation is an option.
Objective:
This study aimed to find the best first intention treatment of very far-advanced otosclerosis.
Materials And Methods:
This was a retrospective study and included 14 patients with non-measurable preoperative bone and air conduction thresholds and otosclerosis on temporal bone high-resolution CT scan. Stapes surgery followed by a well fitted hearing aid was the initial treatment in 11 patients and cochlear implantation in 7 patients, including 4 patients who had poor results after stapedotomy. Objective and subjective audiometric results were studied and compared between stapedotomy and cochlear implantation groups.
Results:
Objective and subjective results were statistically better in the cochlear implant group than in the stapedotomy group. However, four patients in the stapedotomy group had comparable results to the patients with cochlear implants.
