Restore Conductive Hearing
Surgical expertise for otosclerosis and hearing loss involving the stapes bone.
How Otosclerosis Affects Hearing
Otosclerosis is caused by abnormal bone remodeling in the middle ear, most often involving the stapes, the smallest bone in the body. When the stapes becomes fixed, it cannot move normally, which interferes with the transmission of sound to the inner ear. This typically leads to gradually worsening conductive hearing loss that often begins in young adulthood.
Who is at Risk for Otosclerosis?
Otosclerosis often runs in families and is more common in women. It commonly develops during the 20s or 30s and may worsen during pregnancy. Both ears are affected in most cases, although the degree of hearing loss may differ between ears.
Common Symptoms
Gradually worsening hearing, often first noticed in one ear.
Tinnitus, including ringing or buzzing in the ear.
Improved hearing in noisy environments, known as paracusis Willisii.
Dizziness or balance problems may also occur in some patients.
How Otosclerosis is Diagnosed
Audiometry commonly shows conductive or mixed hearing loss. A Carhart notch on the audiogram can suggest otosclerosis, while tympanometry may show reduced middle ear compliance. CT imaging may be used when the diagnosis is uncertain.
Stapedectomy and Stapedotomy
Stapedectomy and stapedotomy are surgical procedures used to bypass or replace the fixed stapes and restore sound transmission. During surgery, the abnormal stapes is addressed and a small prosthesis is placed to allow sound to reach the inner ear. Surgery can be highly effective for appropriate patients.
Alternatives to Stapes Surgery
Hearing aids are another option for patients who prefer not to undergo surgery or who are not surgical candidates. As with any surgery, the potential benefits, risks, and limitations should be discussed with an ear specialist.
