Managing the source
Management of the source
It is important to have a consultation with an Ear, Nose and Throat specialist to eliminate any source of the tinnitus which could be treated. The specialist might recommend some tests, e.g. sinus/neck Xrays or a scan of the head/brain. Treatment might then be as simple as changing your medication (under medical supervision), removing obstructive wax, or treating a middle ear infection. Very often, no particular source for the tinnitus can be found. If the ENT Specialist can do nothing more for your annoying tinnitus, you should seek a consultation with an audiologist or psychologist.
Some things will make tinnitus worse for a short time in some people. Such aggravators may include:
- Stress, worry, fatigue, depression, anxiety, lack of sleep
- Caffeine drinks: coffee, cola, cocoa
- Some medications, e.g. high doses of aspirin or anti-inflammatory agents
- Silence (and hearing impairment)
- Loud noise
- Vigorous exercise
- Clenching or grinding your teeth
- Dental work
- Neck or jaw stiffness or mis-alignment
Management of the aggravators
If you notice that particular drugs or substances you consume or some things you do worsen your tinnitus, you might choose to avoid those things (changing your medications should only be done with the advice of your doctor). Typically, however, these things affect your tinnitus for only a short time and it will not become louder or more annoying indefinitely. Generally speaking, people have reported that their tinnitus became quieter over time rather than louder, therefore aggravators have an insignificant effect in the long term.
Stress, anxiety, depression, fatigue and lack of sleep can aggravate tinnitus as well as trigger it. It is important to learn to recognise and manage such issues as these affect your overall feelings of health and well-being, apart from heightening awareness of the tinnitus. Relaxation training and hypnotherapy are techniques which can help you to relieve mental and physical tension. If you need support to address these issues, you should consult your doctor and/or seek assistance from a psychologist or counsellor.
Jaw-joint problems can cause an increase in muscle tension and intensify your tinnitus. You may wish to consult a dentist or orthodontist about a splint to relieve the pressure on your jaw. Some physiotherapists also provide therapy for jaw and facial tension.
Amplifier – Why is tinnitus annoying?
If the nerves in your hearing system are ‘humming’ at a low level all of the time, why are you not aware of them all the time? The things which determine whether a sound attracts your attention are your past experience, what the tinnitus means to you, and how you feel about it.
Between the ears and the processing of meaning in the brain there is a network of processors, such as pattern receptors. These pattern receptors ‘recognise’ some sounds and allow them pass through to be attended to, but ‘ignore’ other sounds. So, when listening in a crowd you react to hearing your name (it means something to you) but not to many other parts of the conversation. Similarly, the mother of a young baby will wake when the child cries (it requires her to act), although she may sleep through many louder, less meaningful sounds. The pattern receptors develop over time and are related to both the meaning or consequence of the sound and to its emotional importance.
Because pattern receptors have been ‘set’ to exclude unimportant sounds and to respond to important sounds, the loudness of the sound is seldom a major factor. For instance, if you move from a quiet neighbourhood to a house beside a railway line it can take several weeks to adjust to the new sounds, after which you’ll ignore them, even though they continue to be just as loud.
How does the tinnitus sound become important?
Several things may happen when you become aware of tinnitus. First, you may worry about what it means: Do I have a brain tumour? Am I having a stroke? Does this mean I’m going deaf? Does this mean I’m going mad? How can I cope with this unending noise in my head?
These feelings may be encouraged by the comments of some health professionals who may tell you to ‘go home and learn to live with it’, instead of offering the necessary advice and support. You may then come to associate quite strong emotions with the tinnitus due to a sense of helplessness or hopelessness. Because you have been worrying about it and paying it a lot of attention you have successfully tuned your pattern receptors to attend to the tinnitus.
Many people who notice tinnitus pay it little attention. In other words, though they have tinnitus they quickly learn to ignore it and not react it. This is called ‘habituation’ – the tinnitus becomes a ‘habit’ which they no longer notice consciously. Habituation doesn’t happen all at once – it is gradual, and several stages can be recognised:
- You are aware of the tinnitus sound ALL THE TIME
- You have frequent worrying and depressing thoughts
- You find it hard to sustain concentration on mental tasks
- You might have severe insomnia
- You are unaware of the tinnitus for brief periods
- Your concentration improves – you can return to usual activities
- You begin to accept the tinnitus instead of rejecting it all the time
- Your sleep pattern gradually returns to normal
- You are mostly only aware of the tinnitus sound when you are tired or stressed or in quiet
- The tinnitus intrudes mainly when listening and mental concentration are important
- You rarely attend to the tinnitus
- The tinnitus does not intrude into your normal activities
- You find the noises ‘neutral ‘ – they do not evoke any strong feelings
What is Tinnitus Retraining Therapy (TRT)
Two key components of TRT directly follow from the neurophysiological model of tinnitus. One of these principles includes directive counseling aimed at reclassification of tinnitus to a category of neutral signals, while the other includes sound stimulation which is aimed at weakening tinnitus related neuronal activity. The goals of TRT are to help the person habituate to the tinnitus and to stop being aware of it. This is done by an audiologist in the following ways:
- By acknowledging the reality of the tinnitus and its impact on the person
- By providing a thorough explanation of the tests and measures already undertaken to determine the location or cause of the tinnitus and why they indicate that there is nothing seriously wrong with the hearing system
- By describing the structure and function of the hearing system and explaining the mechanisms by which tinnitus becomes dominant
- By providing advice on techniques for relaxing and dealing with tinnitus, to reduce the impact of stress and anxiety
- By providing sound stimulation (with noise generators or an individually-programmed music player device) which can assist the habituation process - this helps to de-tune the pattern processors so that they no longer recognise the tinnitus as something which should be attended to
- By providing hearing aids for people with hearing loss as well as tinnitus – so that the real world of sound can assume importance over the perceived world of tinnitus
- By identifying aggravators and recommending other health professionals who can assist with their management.
