According to the American Academy of Pediatrics, all children (including newborns) should be screened for hearing loss so that hearing loss occurring before birth can be uniformly detected prior to three months of age.
Depending on the type of hearing loss you have, the doctor may order tests to confirm your diagnosis. In selected cases of sudden hearing loss, medical treatment with Intratympanic steroids may be effective.

When medical approaches are not indicated or effective, the use of hearing aids or other types of amplification (i.e. When medical intervention is contraindicated or cannot restore hearing, hearing aids and cochlear implants can provide effective means to better hearing for individuals with sensorineural hearing loss.
The technology, styles and effectiveness are better than ever before, and satisfaction with newer hearing instruments is at an all-time high. Idiopathic sudden sensorineural hearing loss (ISSHL) or “sudden deafness” (SD) is a sudden or rapidly progressive hypoacusis in which no known cause of sensorineural hearing loss can be identified.

This can result from outer or middle ear problems, such as ear infection, excess wax, or swelling.
In cases when loud noise cannot be avoided, you can reduce exposure to loud noises by wearing earplugs, earmuffs, or ear protectors.
Hearing screening for newborns can help insure that hearing loss in young babies is detected and treated at the earliest possible stage.
Examples of conditions that may cause hearing loss and can usually be medically treated are: middle ear infection with fluid build-up, perforation of the eardrum, wax build-up in the ear canal.
Sensorineural hearing loss is usually permanent since hair cells do not repair themselves and cannot be medically treated once damaged. In fact, in more than 95% of all cases of sensorineural hearing loss, hearing aids or cochlear implants are the recommended course of treatment. A study by the National Council on Aging has shown that hearing aids not only help people hear better, but actually improve quality of life for people with hearing loss and their families. It can be caused by heredity or congenital problems, excess noise, old age, medications, infections such as ear infections and meningitis, or from tumors compressing the nerve of hearing such as an acoustic neuroma.
Although research in hair cell regeneration in animals has shown promise, it appears that such treatment for humans is most likely many years away due the many complex scientific issues that have yet to be tackled. Hearing aids and cochlear implants have shown excellent outcomes for people with hearing loss.
Although these hypotheses are controversial, the most likely cause involves impaired oxygen delivery to the organ of Corti. Cochlear activity is dependent on energy supply which is itself directed by the oxygen metabolism; and it has been well demonstrated that perilymphatic oxygen tension decreases significantly in patients with SD.
According to these pathophysiological data, various therapeutic agents (steroids, vasodilators, hemodilution, among others) supposed to enhance rheology and oxidative metabolism have been proposed. In the same way, and due to its general and specific effects, hyperbaric oxygen therapy (HBO) is able to increase perilymphatic oxygen pressure, by restoring the oxidative metabolism in the stria vascularis and by protecting neurosensory cells.
Despite the results of retrospective and prospective studies, their therapeutic efficacy is difficult to establish due partly to the high rate of spontaneous recovery. Nomura, Diagnostic criteria for sudden deafness, mumps deafness and perilymphatic fistula, Acta otolaryngol.
