Hearing impairment and/or sensitivity can occur due to the possibility of hypermobility of the joints between these bones of the middle ear (malleus, incus, and stapes) can create problems with effective sound conduction across the middle ear.This loss of energy in route to the inner ear leads to a mild to moderate conductive hearing loss. Because the inner ear is also responsible for balance, improper function leaves some affected with bouts of dizziness. (Amanda Jenner, Lynne Shields PhD ccc-slp. "EDS Speech and Language Issues")
