OTOSCLEROSIS

Otosclerosis is an ear condition wherein the bone tissues in the middle ear harden due to abnormal calcium deposition around the stapes and oval window. This results in the patient gradual onset hearing loss with or without tinnitus. In the early stages of otosclerosis, the hearing loss is conductive and can be overcome with hearing aids. However, as the conductive loss worsens, the patient will need surgery. Some advanced cases of otosclerosis have calcium deposition within the cochlear which cause sensorineural hearing loss. These advanced cases will need a cochlear implant to be able to hear again.

Otosclerosis has a hereditary component. It classically affects females more than males, with hearing loss worsening with each progressive pregnancy. Certain ethnic groups have a higher incidence of otosclerosis.

TREATMENT

  • Hearing aids
  • Stapedotomy surgery
  • Cochlear implant surgery (for advanced otosclerosis)

PREVENTION

Unfortunately, otosclerosis cannot be prevented. However, timely check-ups and keeping a look out for noticeable symptoms especially if you have a family history of it can help you detect the condition early and start treatment.
