Phantom noise
Your Health - Dr. Gita Mathai
Noise can be loud and irritating. The good thing about external noise is that it can be shut out. Phantom noises — ringing, buzzing, roaring or hissing — varying in intensity and pitch continuous or intermittent, in one or both ears can only be heard by the affected person. They are called tinnitus and cannot be shut out. Sometimes it feels like an insect is trapped in the ear. The sound is disconcerting, and distracting. It is a common problem. The risk of developing tinnitus is higher in men and in smokers. About 25 per cent people experience it by the age of 70.
Tinnitus may be caused by a variety of reasons. It may be due to age. A type of hearing loss called presbycusis often accompanies it. This may be because the fine hair (cilia) in the inner ear die or are damaged. The bones of the inner ear may be damaged. This is called otosclerosis and may run in families. The nerves may not conduct sounds as efficiently. Atherosclerosis and high blood pressure may also cause tinnitus. It may be something as simple as the ear being blocked by wax.
Temporary tinnitus can occur with sudden exposure to a blast of loud noise. This may be accompanied by pain in the ear. Continuous long-term exposure can make the damage permanent. This occurs in younger people who continuously blast music from electronic devices.
Changes in the fluid pressure in the inner ear can occur on one side. It can cause a feeling of vertigo and tinnitus. It is episodic and can be accompanied by hearing loss. It usually goes away on its own in a year or two.
The temporomandibular joint is situated at the angle of the jaw next to the ear. Muscles used in chewing, the ligaments of the jaw and nerves transmitting sounds share some common entities with this joint. Pain, swelling, arthritis or dislocations of this joint or an accident, especially if there has been injury to the head as well, can aggravate tinnitus.
Tumours in the head and neck or the eighth cranial nerve that transmits hearing can cause tinnitus. This can be picked up with CT scans or MRI.
We live in an era where antibiotics are prescribed for the mildest infections. Some of the commonly used antibiotics like erythromycin and gentamicin, and some of the higher ones like vancomycin, polymyxcin and neomycin can affect hearing and cause tinnitus. Diuretics like furosemide (Lasix) and quinine used for malaria can cause similar effects. Aspirin is one of the oldest medications prescribed for pain. In high doses (twelve 300 mg tablets or more) it can cause tinnitus.
Tinnitus is investigated with a hearing tests, CT scans and MRIs. No real cause is usually found. This is depressing for the patient as the continuous sound interferes with sleep and concentration.
Medication does not work well for tinnitus. The irritating sound can be masked with white noise (sounds of waves or rainfall) playing continuously. Hearing aids will help if there is deafness as well.
Some yoga exercises like the triangle pose, camel pose and downward facing dog are found to be beneficial. You can also stimulate the eight nerve by blocking the ears with the forefingers and making an “ooh” sound. Couple this with walking or jogging for 40 minutes a day, light weights and exercises to strengthen the head and neck.
