Superior semicircular canal dehiscence syndrome is a disorder of the ear which was first described in 1995. It is brought on by the thinning or abscence of the temporal bone of the inner ear.

Symptoms of SSCD

  • Balance difficulties
  • Tullio phenomenon: dizziness and involuntary, repetitive eye movements caused by loud noises or pressure
  • Oscillopsia – visual disturbances caused by loud noises or pressure to the ear. Objects appear to oscillate.
  • Tinnitus
  • Hearing loss
  • Autophony – notable awareness of one's body sounds (heartbeat, eye movements, creaking joints, etc.)

Possible Causes of SSCD

  • Congenital
  • Age related thinning of bone
  • Head injury
  • Surgical complication
  • Head pressure from coughing, sneezing, straining

Individuals who present with symptoms of SCDS should consult with an otolaryngologist. A surgical procedure or hearing aids may be indicated.

HI Deirdre, Would you consider adding a section on SSCD (Superior Semi-circular Canal Dehiscence) aka Superior canal dehiscence syndrome (SCDS)? It's a set of hearing and balance symptoms caused by a thinning or complete absence of the part of the temporal bone overlying the superior semicircular canal of the vestibular system. A few of the symptoms are dizziness, vertigo, hearing your heart beat and eyelids blink, blood surging in your neck. I've don't quite a bit of research over the past 17 months and am a candidate for the surgery. I had been having infrequent vertigo attacks for 20 years and wish I had found out sooner as I now have a predicted 80% success rate. It may have been better if I would have been aware of this since my ENTs didn't have the presence of mind to suggest a cat-scan or MRI. SSCD was only discovered in 1998 making it a relatively new disease. There are Youtube videos that explain it well and The Doctors TV show featured it on a segment. It can be quite debilitating and believe this information could help many of your followers. Thank You!

EC: Marsh,

Thank you for sharing this and helping to increase awareness of this issue!

If you look up lions Mane mushroom on amazon, there are a lot of people saying it cured their vertigo, and one person said that her hearing improved 85% from almost nothing.
