Unfortunately, some people do not benefit from the phenomenon of habituation and come to consider their tinnitus as an inconvenience of nature that undermines their quality of life.
Whatever the case may be, the most efficient overall treatment are those that consist in perceptiona€“type therapies, whose aim is to transform the conscious perception of a€?phantom soundsa€? into an unconscious one.
The experiment revealed that there are indeed differences, which corroborates the data of studies carried out in accordance with other protocols (in particular, with positron emission tomography and with electroencephalography) in other centers. This sensation of hearing a buzzing, ringing, swishing or clicking noise in one or both of the ears although no other sound is emanating from the immediate environment has recently been studied by a team of researchers from the Cyclotron Research Centre of the University of LiA?ge and the ENT department of the University Hospital of LiA?ge. If it is subjective, its etiology is difficult to establish because it is not linked to a loss of hearing. Thus, Tinnitus Retraining Therapy (TRT) draws on, among other things, a noise generator suggesting an auditory prosthesis and giving off a noise close to the tinnitus. In addition, these differences in connectivity concern the cortical and sub-cortical regions and include the attentional, emotional and memory systems. The study looks at the problem from the perspective of functional magnetic resonance imaging and has been published in PLoS ONE.Among those who suffer from tinnitus (around 15% of the population), only 10 to 20 percent suffer from it to the point that it alters their quality of life.
Installed by a specially trained audio prosthetist, it must generally be worn for a period of 12 to 18 months.
In this case, tinnitus can leave a comorbidity in its wake in the form of irritability, (and therefore tiredness), concentration problems and depression. Surgical sections of the auditory nerve have been attempted, but without worthwhile results. It is hoped that the patient will become used to the new noise and, indirectly, the noise of the tinnitus which is at a neighboring frequency. As for the regions involved in memory, such as the parahippocampal region, we think that they a€?decidea€™, after comparison with the other sounds picked up as usual, if a perceived noise a€“in this case the tinnitus- must be a€?stifleda€™ or dealt with more deeply because it represents a dangera€? explains Audrey Maudoux.Evidently, if the results recorded by the researchers at the CRC and the ENT department of the University of LiA?ge seem a€?logicala€™, the fact remains that the a€?set of influencesa€? remain hazy. Initially, it was actually believed that tinnitus resulted exclusively from a problem localized in the ear, even though everything indicates today that the problem is essentially a neuronal one.Chronic tinnitus is difficult to treat, all the more so because its etiology is often uncertain. Indeed, the studies carried out do not make it possible to define the initial meaning of dialogue between the cerebral areas. However, much more exceptionally, these noises can be equivalent to about 70 or 80 decibels a€“ a normal conversation is at about 55 decibels. Also, from a therapeutic point of view, ita€™s as if we treated apples pears and bananas in the same waya€?, explains Philippe LefA?bvre.There is no objective parameter which makes it possible to measure the intensity of tinnitus. When it is accompanied by loss of hearing, the wearing of a hearing aid can improve the situation substantially from both viewpoints.
If emotional force is a major factor in the intolerance of the tinnitus given its inextinguishable permanent character, the patient knows in this case that he can a€?switch offa€? the sound at any time by disconnecting the noise generator. Is it the auditory region that influences the activity of the attentional, emotional and memory areas or is it the latter that initiates the exchange of information?
In those who do not feel handicapped by their tinnitus a phenomenon called habituation comes into play: the brain filters the parasitical information to the extent that the a€?phantom noisesa€?A are banished to the subconscious. Therefore the doctor has no other choice than to rely on the subjective assessment of the tinnitus sufferer. This question is highly significant, as it is at the center of questions relative to the etiology of the problem and the way to treat it.
As Professor Lefebvre points out, it is the same mechanism which prevents us from focusing our attention on the ticking of a clock or the rubbing of our clothes against the body.Subjective evaluationA A  In fact there are two types of tinnitus. Philippe LefA?bvre adds that a broad approach must be adopted when treating the tinnitus patient.Another technique which is very popular is self-hypnosis which aims to allow the patient to adjust his sensations, to control them and therefore to push the tinnitus into his unconscious mind. These are practically the only medicines that have proved to be efficient with regard to tinnitus in the acute phase. Cognitive behavioral therapies are regularly used to combat chronic tinnitus and are also a valued method.
In addition, it has been demonstrated that its frequency (low-pitched or high-pitched) does not have an impact on whether or not the patient is bothered or not by its presence. Several other medicinal approaches are offered in the context of chronic tinnitus, but with limited success: magnesium, Ginkgo biloba, vasodilators, anticonvulsants or even anxiolytics or anti-depressants.

In an entirely different approach, transcranial magnetic stimulation is used in experimental treatments. They are generally the result of a vascular deformation (for example, a blowing noise can be heard around the carotid) and for this reason are of the pulsatile kind as they are synchronized with the beating of the heart, or call to mind the idea of swishing, (blood flow). As underlined by Professor Lefebvre, it would be necessary to identify sub-groups of patients in order to hope to obtain more conclusive results.
One thing is certain: silence is one of the main enemies of the individual suffering from tinnitus. In addition, treatment by laser has been added to the list but the efficiency of this method has not been proved by any placebo-controlled scientific study.A  Another technique which is invasive and reserved for rigorously selected cases, involves the implantation of electrodes in the brain.
This should be avoided (in isolation, with the help of background music for example), in order to prevent the individual from focusing on parasitical noises. However, with a sample of only 13 tinnitus patients, we have only been able to show a trend. Linked to a malfunctioning of the auditory pathway, they are only experienced by the individual suffering from them.
Tinnitus can also have other medical causes that we can expect to resolve: for example, hypertension, a neurinoma or a cerebral vascular problem. Practised in Belgium by Professor Dirk De Riddera€™s group, from the University of Antwerp, this approach has resulted in positive results in two-thirds of patients treated. Paying attention to these noises all the time only has the effect of increasing the discomfort caused by them. We are going to try to refine and reinforce the results of our different work by analyzing a group of around one hundred patientsa€?, says Audrey Maudoux.The results published in PLoS ONE are the results of a group study.
Often, however, the etiology of tinnitus remains poorly defined and treatments during the acute phase have not been crowned with success. A Several networksAs we have pointed out, the underlying physiopathological mechanism of tinnitus remains little-known.
The first includes tinnitus caused by an increase in the frequency of potential action discharges in the cochlea (ciliated cells, neurons).
When the brain no longer receives some sensitive information from the periphery (this is called deafferentation?), a functional reorganization is produced (principally hyperactivity) in the cerebral areas that, in this case, process sound information. Recently, researchers at the Cyclotron Research Centre of the University of LiA?ge and the ENT department of the University Hospital of LiA?ge set about recording the cerebral activity of 28 subjects, 13 of whom suffer from unilateral or bilateral tinnitus.
Future work based on a larger sample will perhaps enable us to distinguish several types of tinnitus and to define their individual characteristics.

In addition, longitudinal a€?resting-state FMRIa€? monitoring would be of great interest because it would make it possible to determine the variations in the cerebral activity of a subject according to whether his tinnitus remained stable, disappeared, is better tolerated or becomes intolerable.
The second category consists of tinnitus whose primary cause is a deterioration of hearing acuity, particularly with age.
The tinnitus may disappear one day for an unknown reason, stay with the individual for life and vary in terms of its intensity or form.
The deterioration in the function of the auditory pathway is accompanied by a reduction of inhibitions in the cerebral cortex. Once they are reassured as to the benign nature of their tinnitus, which is the most common situation, most individuals are no longer disturbed by the phantom noises that characterize it- the brain succeeds in confining the problem to the unconscious. This suggests that the brain attempts to compensate for the loss of hearing by increasing its activity and this generates a€?phantom soundsa€?.
