Cochlear implant surgery is a surgical procedure that involves placing (implanting) a small electronic device into the ear to help the person hear well. The implant is placed when someone is not able to hear and understand spoken words even after using hearing aids. The cochlear implant sends electrical signals to the nerve involved in hearing (cochlear nerve). Read more: How Long Does It Take to Recover From Cochlear Implant Surgery? Article

Related Disease Conditions
Hearing loss (deafness) may be present at birth or it may manifest later in life. Deafness may be genetic or due to damage from noise. Treatment of deafness depends upon its cause. Sensorineural hearing loss can be caused by conditions affecting the: cochlea, eighth cranial nerve, spinal cord, or brain. Examples of conditions that can lead to sensorineural hearing loss include: Meniere's disease, noise-induced hearing loss hearing loss of aging (presbycusis), nerve injury from syphilis, hearing loss of unknown cause (idiopathic hearing loss), nerve tumors, and drug toxicity (such as aspirin and aminoglycosides).
Noise Induced Hearing Loss and Its Prevention
Noise-induced hearing loss may be an acoustic trauma, which causes temporary hearing loss, or it may be permanent due to an acute acoustic trauma. Experts agree that continual exposure to more then 85 dBs (decibels) is dangerous to the ears. Ear plugs and ear muffs can help prevent noise-induced hearing loss as well as decreasing exposure to loud noises.
