Otitis media, or middle ear infection, is the most common cause of hearing loss in children. It is caused by a bacterial or viral infection of the middle ear, which can lead to fluid buildup and inflammation, resulting in temporary hearing loss.

Tinnitus, dizziness, and ear pain can all be symptoms of hearing loss. Tinnitus is a ringing, buzzing, or hissing sound in the ears, while dizziness can be caused by an imbalance in the inner ear. Ear pain can be a sign of an infection or other underlying condition that is causing hearing loss.

Age-related hearing loss, also known as presbycusis, is a gradual loss of hearing that occurs with age. It is caused by changes in the inner ear and auditory nerve, and is the most common type of hearing loss.

Conductive hearing loss is caused by damage to the outer or middle ear, which prevents sound waves from reaching the inner ear. This can be caused by a variety of factors, such as earwax buildup, otitis media, or a perforated eardrum.

Noise-induced hearing loss can be caused by exposure to loud music, industrial noise, or military service. All of these can cause damage to the hair cells in the inner ear, leading to hearing loss.

Conductive hearing loss can be treated with hearing aids, cochlear implants, or surgery. Hearing aids amplify sound waves to make them louder, while cochlear implants bypass the damaged hair cells in the inner ear and directly stimulate the auditory nerve. Surgery may be an option to correct an underlying cause of conductive hearing loss, such as a perforated eardrum or otitis media.

Age-related hearing loss is the most common cause of sensorineural hearing loss. It is caused by changes in the inner ear and auditory nerve, and is a gradual loss of hearing that occurs with age.

Ménière's disease is a disorder of the inner ear that can cause hearing loss, tinnitus, and dizziness. These symptoms can come and go, and may be accompanied by a feeling of fullness in the ear.

Viral infections, such as the mumps or measles, are the most common cause of sudden hearing loss. These infections can damage the hair cells in the inner ear, leading to hearing loss.

Age, noise exposure, and smoking are all risk factors for hearing loss. Age-related hearing loss is the most common type of hearing loss, and noise exposure and smoking can both damage the hair cells in the inner ear, leading to hearing loss.

Hearing aids, cochlear implants, and bone-anchored hearing aids are all devices that help people with hearing loss hear better. Hearing aids amplify sound waves to make them louder, while cochlear implants bypass the damaged hair cells in the inner ear and directly stimulate the auditory nerve. Bone-anchored hearing aids are surgically implanted devices that transmit sound waves directly to the inner ear.

Behind-the-ear (BTE), in-the-ear (ITE), and in-the-canal (ITC) are all types of hearing aids. BTE hearing aids are worn behind the ear, with a small tube that fits into the ear canal. ITE hearing aids are worn in the outer ear, and ITC hearing aids are worn in the ear canal.

Stapedectomy, tympanoplasty, and mastoidectomy are all surgical procedures that can improve hearing in people with conductive hearing loss. Stapedectomy is a procedure to replace a damaged stapes bone in the middle ear, while tympanoplasty is a procedure to repair a perforated eardrum. Mastoidectomy is a procedure to remove infected or diseased tissue from the mastoid bone behind the ear.

Age-related hearing loss, noise-induced hearing loss, Ménière's disease, and autoimmune disorders are all types of sensorineural hearing loss. Sensorineural hearing loss is caused by damage to the inner ear or auditory nerve, and is a permanent loss of hearing.

Hidden hearing loss is a condition in which a person has difficulty understanding speech in noisy environments, even though their hearing test results are normal. This is because hidden hearing loss affects the way the brain processes sound, rather than the ear itself.
