Hearing loss or deafness is the partial or total inability to hear sounds in one or both ears. The ear has three main parts - outer ear, middle ear and inner ear. Sound waves that travel through the outer ear result in vibrations at the eardrum (present between the outer and middle ear). These vibrations then pass through and are amplified by three small bones of the middle ear to reach a fluid present in the cochlea, a snail shell like organ in the inner ear. Cochlea has tiny hairs attached to nerve cells that help in translating the vibrations into electrical signals, which are then transmitted to the brain via the auditory nerve.
Depending on the cause, hearing loss is of the following types:
- Conductive hearing loss: Conductive hearing loss is due to problems with sound transmission between the outer and inner ear. The common causes for this type of deafness are wax build-up in the ear canal, damage to the small bones that are behind the eardrum, fluid in the middle ear after an ear infection, a hole or scar on the eardrum or a foreign object in the ear.
- Sensorineural hearing loss: It happens due to damage to the inner ear and is usually permanent. This type of hearing loss is commonly caused by exposure to loud noise, ageing, childhood infections, Meniere’s disease, heredity, autoimmune disease, malformation of the inner ear, tumour and head trauma.
- Mixed hearing loss: A combination of both conductive and sensorineural hearing loss is called ‘mixed’ hearing loss.
Conventionally, hearing loss is treated on the basis of the underlying cause. Hearing aids and implants are suggested if necessary.
Homeopathy is a holistic system of medicine that aims to treat the whole individual instead of just treating the disease. A unique remedy is chosen for every individual based on the totality of their symptoms and the person's age, health and other factors. Baryta carbonica, belladonna, chenopodium anthelminticum, graphites, kalium muriaticum, lycopodium clavatum, petroleum, silicea terra and verbascum thapsus are some homeopathic remedies that are effective in the treatment of hearing loss.
