In Belgium the product is sold under the name "Rilatine" and in Brazil and Portugal as "Ritalina". Hearing by bone conduction occurs when sound waves cause the bones of the skull to vibrate which directly stimulate the hearing organ (cochlea) resulting in hearing. Conductive Hearing Loss occurs when sound waves cannot be transmitted properly from the external environment to the cochlea.
Obstruction in the external ear canal caused by wax, foreign body or infection (otitis externa). Dislocated, damaged or fi xed ossicles (malleus, incus, or stapes) – from trauma or chronic diseases that erode the ossicles over time or otosclerosis that cause the ossicles to be fixed.
Sensorineural Hearing Loss occurs when there is damage to the hearing organ (cochlea) or hearing nerve (auditory nerve). Acute and chronic exposure to loud noise can cause damage to the sensory cells in the cochlea.
Acoustic neuroma - a tumour of the vestibular nerve, which lies in close proximity to the auditory nerve and affects its function. Ototoxic drugs – Some drugs can damage the nerves involved in hearing or the sensory cells in the cochlea.
The affected person usually complains of diffi culty in holding a normal conversation, especially in a noisy environment. There may be associated symptoms like tinnitus (ringing in the ears) or vertigo (spinning sensation). A complete history, ENT examination and relevant investigations are necessary for a diagnosis.


A hearing test (audiogram) will be performed to confirm the presence and indicate the severity and type of hearing loss.
For presbycusis (hearing loss due to old age) no treatment is needed although the affected individual will be advised to protect his hearing and evaluated on whether hearing aid help is needed. Conventional hearing aids are amplification devices that detect environmental sounds and present and amplify them into the external ear canal.
The side effects from wearing hearing aids include occlusion effect (sense of blockage of the ear), feedback and a propensity for ear infections. In air conduction, sound waves travel through the external ear canal to vibrate the eardrum. The problem could lie in the external ear canal, eardrum, middle ear bones or middle ear space.
There may be complaints from others around that the person does not respond when called or speaks louder than normal. People who work with heavy machinery or in the construction industry should use proper ear protection when working around loud noises, especially when working for prolonged periods. The ENT physician will perform a thorough head and neck examination, particularly of the ear canal and tympanic membrane. Treatment may range from observation and reassurance to medications and a discussion on surgical options. The ENT surgeon will insert the electrical electrode of the implant directly into the cochlea and directly stimulate the nerve endings in the cochlea so as to bypass any problem in the cochlea. Vibration of the eardrum is transmitted to the hearing organ (cochlea) via three small bones (ossicles) in the middle ear.


They should also undergo regular hearing tests to ensure that their hearing is not worsening.Youngsters should not use earphones or visit discotheques.
Radiological imaging studies such as CT scans or MRIs (magnetic resonance imaging) may be ordered to detect an acoustic neuroma. If the cause of hearing loss is due to wax and foreign body in the ear canal, it can be removed under a microscope by the ENT surgeon. Surgical repair of the ear perforation may be necessary if the perforation persists for more than three months or there is a problem of recurrent ear infections with ear discharge.
The modern aids vary from very small completely-in-the-canal to the traditional behind the ear hearing aids. Middle ear implants are used in people who have tried hearing aids but are unable to use them or fail to benefit from them. This stimulates the sensory cells in the cochlea which then sends impulses to the hearing nerve (auditory nerve) and on to the brain. If the cause of the hearing loss is due to medication, the medication will be stopped or changed. It comprises of a transducer that is attached to the ossicles or directly to the round window (part of the cochlea).
