About
Otosclerosis is an inherited disorder affecting the middle ear, where abnormal bone growth around the stapes bone (one of the three ossicles) leads to its fixation. This fixation impairs the stapes’ ability to vibrate, resulting in conductive hearing loss. The exact cause is unknown, but genetic factors play a significant role, and the condition often worsens during periods of hormonal change, such as pregnancy.
Symptoms
Gradual Hearing Loss: Typically starting in one ear and potentially progressing to both.
Worsening in Pregnancy: Some individuals experience a noticeable decline in hearing during pregnancy.
Tinnitus: Ringing or buzzing sounds in the affected ear.
Causes
Genetic Predisposition: Family history increases the risk of developing otosclerosis.
Hormonal Influences: Hormonal changes, especially during pregnancy, can exacerbate the condition.
Environmental Factors: While less understood, certain environmental factors may contribute.
Diagnosis
Audiometric Testing: Evaluates the degree and type of hearing loss.
Tuning Fork Tests: Assesses bone and air conduction hearing.
Imaging Studies: CT scans may be used to visualize bone changes in the middle ear.
Treatment & Prevention
Hearing Aids: Amplify sound for those with mild to moderate hearing loss.
Surgical Intervention: Stapedectomy involves removing the immobilized stapes and replacing it with a prosthesis to restore hearing.
Observation: Regular monitoring if hearing loss is minimal and does not interfere with daily activities.
