Semicircular canal dehiscence syndrome (SCDS) is a rare inner ear disorder caused by a thinning or complete absence of part of the bone overlying the semicircular canals of the inner ear. This can lead to a variety of symptoms, including vertigo, hearing loss, tinnitus, and a feeling of fullness in the ear. SCDS is usually diagnosed with imaging tests such as CT or MRI scans. Treatment typically involves surgical repair of the dehiscence.

The most common symptoms of Semicircular Canal Dehiscence Syndrome (SCDS) include:
* Vertigo or dizziness
* Unsteadiness or imbalance
* Autophony (hearing one's own voice or heartbeat in the ear)
* Tinnitus (ringing in the ear)
* Hyperacusis (increased sensitivity to sound)
* Pressure or fullness in the ear
* Hearing loss
* Visual disturbances
* Nausea and vomiting
* Cognitive disturbances

Semicircular canal dehiscence syndrome is caused by a defect in the bone that separates the inner ear from the brain. This defect can be caused by a variety of factors, including congenital malformations, trauma, or surgery. In some cases, the cause is unknown.

1. Surgery: The primary treatment for semicircular canal dehiscence syndrome is surgical repair of the dehiscence. This involves reconstructing the bony covering of the affected semicircular canal.

2. Vestibular rehabilitation: Vestibular rehabilitation is a form of physical therapy that can help to reduce symptoms of dizziness and imbalance associated with semicircular canal dehiscence syndrome.

3. Medication: Medications such as antihistamines, anticholinergics, and benzodiazepines can be used to reduce symptoms of dizziness and imbalance.

4. Balance retraining: Balance retraining exercises can help to improve balance and reduce dizziness associated with semicircular canal dehiscence syndrome.

5. Hearing aids: Hearing aids can be used to reduce the symptoms of hearing

1. Previous ear surgery
2. Congenital malformations of the temporal bone
3. Trauma to the temporal bone
4. Chronic ear infections
5. Autoimmune diseases
6. Genetic predisposition
7. Exposure to loud noises
8. Aging

At this time, there is no known cure for Semicircular Canal Dehiscence Syndrome (SCDS). However, there are medications that can help manage the symptoms of SCDS. These medications include anti-vertigo medications, such as meclizine and diazepam, as well as anti-nausea medications, such as ondansetron. Additionally, vestibular rehabilitation therapy can help to reduce the symptoms of SCDS.
