Far-advanced otosclerosis.

ABSTRACT

Profound deafness has received increasing attention in recent years, largely because of the availability of cochlear implants. Consequently, it is especially important for otolaryngologists to remember that a "blank" audiogram does not necessarily mean total or even profound deafness. Patients with far-advanced otosclerosis may have no measurable hearing with routine audiometric testing even in the presence of serviceable sensorineural hearing. Review of nine patients (10 ears) who underwent stapedectomy from 1980 to 1987 reveals that seven of the nine (78%), who had been unable to use a hearing aid preoperatively, obtained serviceable hearing with hearing aids following surgery. Otolaryngologists should depend on a good history and tuning fork examination to avoid being misled by the audiogram, and should not hesitate to offer stapes surgery to patients with far-advanced otosclerosis.
