Otosclerosis is a common cause of conductive hearing loss. With a partial hearing loss:
A. Stapedectomy is the procedure of choice.
B. Hearing aids usually restore some hearing.
C. The client is usually unable to hear bass tones.
D. Air conduction is more effective than bone conduction.
Correct Answer: B. Hearing aids usually restore some hearing.
With a partial hearing loss that auditory ossicles have not yet become fixed; as long as vibrations occur, a hearing aid may be beneficial. Hearing aids are devices designed to improve audition up to 40 to 60 dB with good results. They require individualized fittings and venting plans and can be very expensive. The overall results are very good.
Option A: Performing a stapedectomy serves as a way to re-establish sound transmission through an ossicular chain that has likely been stiffened through the disease process known as otosclerosis, which has caused a conductive hearing loss.
Option C: Hearing can be effectively restored via cochlear implantation, but global neurologic status, in addition to family care and speech therapy, are paramount to maximize the benefits of this surgery.
Option D: Chronic or refractory, inoperable, conductive hearing loss can be treated with bone-conduction hearing aids or via a BAHA, a bone-implanted conduction aid, with excellent results.
