Understanding Otosclerosis

What is Otosclerosis?

Otosclerosis is a condition affecting the middle ear, where abnormal bone growth interferes with the normal function of the stapes bone, leading to hearing loss.

Key Facts

• Most common in adults between 20-40 years old
• Women are twice as likely to be affected
• Often runs in families
• Can affect one or both ears

Symptoms

Primary Symptoms

• Gradual hearing loss
• Difficulty hearing low-pitched sounds
• Better ability to hear when there's background noise
• Tinnitus (ringing in the ears)

Progressive Nature

• Symptoms typically develop slowly over several years
• Hearing loss may initially come and go
• Can eventually become permanent if untreated

Diagnosis

• Detailed medical history
• Physical examination of the ear
• Hearing tests (audiometry)
• Tympanometry to test eardrum movement

Treatment Options

Conservative Management

• Hearing aids
• Regular monitoring
• Calcium and vitamin D supplements (in some cases)

Surgical Treatment

• Stapedectomy/stapedotomy
  • Removal of affected bone
  • Replacement with prosthesis
  • Success rate of approximately 90%

Living with Otosclerosis

• Regular hearing check-ups
• Protection from loud noises
• Communication strategies
• Support groups and resources

When to See a Doctor

• Progressive hearing loss
• Persistent tinnitus
• Balance problems
• Family history of hearing loss

Prognosis

With proper treatment, most patients experience significant improvement in hearing and quality of life.
