The prevalence of Semicircular canal dehiscence syndrome (SCDS) is estimated to be around 0.5% to 1% of the general population. SCDS is a rare condition characterized by a thinning or absence of bone in the semicircular canals of the inner ear. This can lead to various symptoms including hearing loss, vertigo, and sensitivity to certain sounds. While the exact cause of SCDS is not fully understood, it is believed to be a congenital condition that may become symptomatic later in life. Diagnosis is typically made through a combination of medical history, physical examination, and imaging tests.
Semicircular canal dehiscence syndrome (SCDS) is a rare condition characterized by a thinning or absence of bone overlying the semicircular canals in the inner ear. This can lead to abnormal sound and pressure sensitivity, as well as balance and hearing problems. The prevalence of SCDS is not well-established, but it is estimated to affect approximately 0.1% to 0.5% of the general population.
SCDS was first described by Dr. Lloyd Minor in 1998, and since then, more cases have been identified as awareness of the condition has increased. It is believed that SCDS may be underdiagnosed due to its relatively low prevalence and the variability of symptoms among individuals.
While SCDS can occur at any age, it is most commonly diagnosed in individuals between the ages of 30 and 60. Women are slightly more affected than men, with a ratio of approximately 2:1.
Diagnosis of SCDS involves a thorough medical history, physical examination, and specialized tests such as a vestibular evoked myogenic potential (VEMP) test or a high-resolution computed tomography (CT) scan. Treatment options include observation, lifestyle modifications, and surgical intervention to repair the dehiscence.
