Ear conditions can cause problems with your hearing or balance, states the U.S. National Library of Medicine. The outer, middle and inner ear contribute to hearing, while the inner ear also controls balance. Ear conditions affecting the inner ear, such as Meniere's, can cause dizziness, while other conditions can cause permanent hearing loss or deafness. Treatment for these conditions include medications and hearing aids.
