Otosclerosis\nis an abnormal growth of bone in the middle ear that causes hearing loss. It\ntypically begins in the early 20s, and is the leading cause of middle ear\nhearing loss in young adults. <\/p>\n\n\n\n
The exact cause of otosclerosis is not known, but evidence suggests a genetic link passed down from parent to child. Middle-aged Caucasian women are most at risk, and hormonal changes seem to be a contributing factor including pregnancy and menopause. This bone growth usually occurs around the stapes bone in the middle ear, preventing it from moving freely, essential to proper hearing. <\/p>\n\n\n\n
Gradually worsening hearing loss is\nthe primary symptom of otosclerosis. It may begin with an inability to hear\nlow-pitched sounds or whispers. Other symptoms may include vertigo or dizziness\nand tinnitus (ringing in the ears). <\/p>\n\n\n\n
The symptoms of otosclerosis are like those\nof other conditions, so a thorough examination by an otolaryngologist is essential\nin ruling out other problems and diagnosing the disease. A hearing test will\nusually show signs of conductive hearing loss in the lower frequency tones, a\nhallmark of otosclerosis. <\/p>\n\n\n\n
Mild cases of otosclerosis can be\ncorrected with a hearing aid designed to amplify sounds. Orally ingested sodium\nfluoride has been shown to slow the progression of the disease, and may be an\noption. <\/p>\n\n\n\n
In more advanced cases, a surgical\nprocedure known as a stapedectomy is often performed. In this surgery, part or\nall of the affected stapes bone is removed and replaced with a prosthetic\ndevice that enables the bones of the middle ear to resume movement, allowing\nsound waves to reach the inner ear, improving or restoring hearing. <\/p>\n\n\n\n
There are inherent risks in any\nsurgery, but left untreated, otosclerosis will only get worse. Speak to your\ndoctor about the best treatment options for your hearing loss. <\/p>\n\n\n
