Otosclerosis is an abnormal\ngrowth of bone in the middle ear that causes hearing loss. It typically begins\nin the early 20s, and is the leading cause of middle ear hearing loss in young\nadults. <\/p>\n\n\n\n
The exact cause of\notosclerosis is not known, but evidence suggests a genetic link passed down\nfrom parent to child. Middle-aged Caucasian women are most at risk, and\npregnancy seems to be a contributing factor, perhaps due to hormonal changes a\nwoman is undergoing at the time. This bone growth usually occurs around the\nstapes bone in the middle ear, preventing it from moving freely, essential to\nproper hearing. <\/p>\n\n\n\n
Gradually worsening hearing\nloss is the primary symptom of otosclerosis. It may begin with an inability to\nhear low-pitched sounds or whispers. Other symptoms may include vertigo or\ndizziness and tinnitus (ringing in the ears). <\/p>\n\n\n\n
The symptoms of otosclerosis\nare like those of other conditions, so a thorough examination by an\notolaryngologist is essential in ruling out other problems and diagnosing the\ndisease. A hearing test will usually show signs of conductive hearing loss in\nthe lower frequency tones, a hallmark of otosclerosis. <\/p>\n\n\n\n
Mild cases of otosclerosis can\nbe corrected with a hearing aid designed to amplify sounds. Orally ingested\nsodium fluoride has been shown to slow the progression of the disease, and may\nbe an option. <\/p>\n\n\n\n
In more advanced cases, a\nsurgical procedure known as a stapedectomy is often performed. In this surgery,\npart or all of the affected stapes bone is removed and replaced with a\nprosthetic device that enables the bones of the middle ear to resume movement,\nallowing sound waves to reach the inner ear, improving or restoring hearing. <\/p>\n\n\n\n
There are inherent risks in\nany surgery, but left untreated, otosclerosis will only get worse. Speak to\nyour doctor about the best treatment options for your hearing loss. <\/p>\n\n\n
