What is the major risk factor for developing hearing loss caused by otosclerosis?

The major risk factor for developing hearing loss caused by otosclerosis is family history and being female. Otosclerosis is a condition characterized by abnormal bone growth in the middle ear, which can cause conductive hearing loss. This condition has a hereditary component, meaning it can run in families. Additionally, it is more commonly diagnosed in females, particularly during their reproductive years, suggesting that hormonal factors may play a role in its development.

While age can be a contributing factor to many forms of hearing loss, otosclerosis specifically tends to affect younger adults. Exposure to loud noises is connected to noise-induced hearing loss, not specifically to otosclerosis. Chronic ear infections can lead to other types of hearing impairment but are not directly linked to the development of otosclerosis. Understanding these distinctions helps clarify why family history and female gender are strongly associated with this condition.
