However, Menibre's sudden onset and timescale of symptoms, and their propensity to recur, are more similar to TAD's features than to those of SSHL.

Approximately 4,000 new cases of SSHL occur each year in the United States.
Only 10 to 15 percent of patients with SSHL know what caused their loss.
People who experience SSHL should see a physician immediately.
Steroid treatment helps some SSHL patients who also have conditions that affect the immune system, which is the body's defense against disease.
Researchers believe that this method aids people with SSHL who also have Meniere's disease, a hearing and balance disorder.
