Superior Canal Dehiscence Syndrome
Superior Canal Dehiscence Syndrome (SCDS) is a rare vestibular disorder caused by a thinning or opening (dehiscence) in the bone covering the superior semicircular canal of the inner ear. This abnormal opening can lead to a wide range of symptoms that impact both hearing and balance—including vertigo, sensitivity to sound, and a strange awareness of internal noises like your heartbeat or footsteps.
At Sparq Physical Therapy in Castle Rock, CO, we understand how disorienting and frustrating SCDS can be. Whether you’re waiting for surgical treatment or looking for long-term symptom management, vestibular therapy can help reduce dizziness, improve balance, and enhance your ability to function with confidence.
Affected Area
SCDS affects the superior semicircular canal of the inner ear, which plays a role in detecting head motion and maintaining balance. Due to the abnormal opening in the canal, it can also impact the auditory system, leading to unusual sound sensitivities and pressure sensations. Over time, this can cause secondary dysfunction in the eyes, postural muscles, and central balance pathways.
Symptoms
Common symptoms of SCDS include vertigo triggered by loud sounds (Tullio phenomenon) or pressure changes, imbalance, visual blurring with movement (oscillopsia), autophony (hearing your own voice, heartbeat, or footsteps unusually loud), and motion sensitivity. These symptoms may worsen with physical activity, noise, or positional changes.
Treatments
While surgical repair may be required for some cases, vestibular physical therapy can help improve function and reduce the impact of symptoms—especially when surgery is not an immediate option. At Sparq PT, your rehab plan is designed to address your unique challenges and may include:
Gaze stabilization exercises to reduce visual disturbances during head movements
Balance and coordination training to improve steadiness in daily activities
Desensitization strategies to help reduce symptom triggers like motion or sound
Postural control exercises to support safe movement and reduce fall risk
Education and coping techniques to better manage symptoms and improve quality of life
Even with a rare condition like SCDS, you’re not alone. Our team is here to help you regain stability, clarity, and control—one step at a time.
