SymptomsHearing loss (mild to worse) is the main symptom. Some people may also experience vertigo or dizziness, balance problems or tinnitus (ringing in the ears).
Otosclerosis tends to target one ear at first, but both ears are eventually affected.
CausesThe exact cause is not known. Risk factors include:
- Family history
- Females are more likely to develop than males
- People with osteogenesis imperfect (abnormal brittle bones)
- Caucasians (white people) are more likely to develop this condition
- Viral infections like measles
- Drinking nonfluoridated water
