Tinnitus is the subjective perception of noise inside the ear without there being an outside sound source causing it. The subjective sounds can be perceived in one ear, in both ears or as a centralized ‘in the head’ noise.
Tinnitus impacts the life of about 700 000 Quebecers, 10% of whom the symptoms significantly impair their quality of life. A multidisciplinary team approach including the expertise of an audiologist, an ENT specialist and a psychologist is often needed for optimal treatment. Brain stimulation techniques Brain stimulation techniques designed to stimulate the auditory cerebral cortex of the brain can be used to reduce tinnitus.
Noise-generators Noise-generators can be used to create a soothing background noise to mask tinnitus. Professional support and rehabilitation programsProfessional support and rehabilitation programs can reduce the negative emotional impacts of tinnitus. Relaxation techniques Relaxation techniques such as Yoga and other forms of physical activity such as walking and swimming can reduce the effects of tinnitus. Alternative approaches Alternative approaches like acupuncture and naturopathy can be used. Tinnitus is best managed when the individual fully understands the condition, its irritants and treatment options.

Definition: Tinnitus could be defined as perception of noise in the absence of acoustic stimuli.
Prevalance: Studies have shown that nearly 20% of adults experience tinnitus in one form or the other.
Hearing loss: Studies conducted in Canada showed people with deafness had increased incidence of tinnitus. Tinnitus in children: Increased incidence of otitis media in pediatric age group plays an important role in high prevalance of tinnitus in children. Classification of tinnitus: One simplistic classification of tinnitus could be Subjective and Objective tinnitus.
Pulsatile tinnitus: May be classified into vascular and non vascular types according to its etiology. Non vascular types of pulsatile tinnitus include palatal myoclonus, tensor tympani myoclonus, and stapedial myoclonus. Classification schemes available: Various classification schemes have been suggested by various authors.
Nodar's classification: This classification was based on the importance of 6 factors related to tinnitus. Modified Nodar's classification: In 1996 Nodar came out with a new version of his classification. Subjective tinnitus can be compared to phantom sensations which occur after amputation of limb.
Auditory feed back system and its role in tinnitus generation: The optimal operation of auditory system is dependent on very sensitive and complex feed back mechanisms involving the afferent (ascending), efferent (descending) pathways. Nervous system as the site of tinnitus: Most forms of severe tinnitus have been shown to be caused by abnormal functioning of the nervous system.
Vascular contact with the intracranial portion of auditory nerve is regularly associated with tinnitus.
A good history is a must for accurate diagnosis of the underlying pathology leading on to tinnitus.

Etiology of objective tinnitus include: intracranial vascular anamolies, atherosclerosis of aorta, pseudotumor cerebri, chemodectomas involving the middle ear. Pitch estimation: Pitch estimation of tinnitus helps in the probable etiology for tinnitus. Masking: Refers to the reduction of audibility of tinnitus when the patient is exposed to another sound. Lyme disease is an infection caused by a bacterium (a germ) that is commonly transmitted by a bite from an infected deer tick.
Diagnosis of Lyme disease can be difficult because its symptoms are similar to other diseases.
Among people who experience sudden hearing loss, lab tests have shown them to test positive for the bacterium or antibodies against the bacterium at a rate that was six times higher than the average population.
A study published in late in 2012 reported a progressive bilateral sensorineural hearing loss in stage 3 Lyme disease. It is not a disease, but rather a symptom of anomaly in the hearing system or the upper auditory pathways .
Although tinnitus is most commonly accompanied by a hearing loss, people with normal hearing acuity can equally suffer from tinnitus.
Occasionally, the added expertise of a hearing aid acoustician or a neuropsychologist will prove necessary. Consequently, alternative treatment methods with variable therapeutic effects are proposed. It develops adapted solutions for individuals, institutions and businesses, to ensure the independence and social well-being of the hard of hearing. Factors affecting the prevalance of tinnitus include: age, gender, race, economic status, hearing loss and noise exposure. Patients belonging to otologic category include those with disease of external or middle ear, cerumen impaction, abnormal mobility of ear drum or ossicular chain, and abnormal contractions of the middle ear musculature. It includes history and physical examination, audiological testing, vestibular evaluation and radiologic studies. Alteration in the stereocilia that are attached to the outer hair cells could be the exact cause. The auditory pathway is also linked with other extra auditory structures like reticular (serotonergic), somatosensory, hypothalamic and limbic systems thus making a tight integration with the central nervous system network. This disorder includes a triad of symptoms which include fluctuating hearing loss, roaring tinnitus and vertigo. Noise and ototoxic drugs cause damage to hair cells of cochlea depriving auditory input to the brain. Infact tinnitus could be the first symptom of a vestibular schwannoma, it becomes worse after surgical removal of schwannoma.
Severity of tinnitus should be assessed (ie whether present throughout the day - severe tinnitus, present only in the absence of ambient noise - night times - mild tinnitus). Tympanometry and stapedial reflex test - to identify middle ear pathology and evaluate the neural pathway for stapedial reflex. High pitched tinnitus is common in patients with noise induced hearing loss, and low pitched tinnitus is commonly seen in Menier's disease. Although April through October is considered to be prime tick season; Lyme disease can be transmitted by a tick at any time of year. Several days or weeks after a bite from an infected tick, the patient may experience flu-like symptoms such as aches and pains in their muscles and joints, low-grade fever and fatigue.
This feature is different from hearing loss in stage 2 Lyme disease, which has essentially been reported to be unilateral and sudden.

Multiple sensorineural and conductive hearing loss types can be accompanied by tinnitus, most notably a noise-induced hearing loss. However, these sounds can present themselves in different forms, namely hissing, buzzing, clicking or roaring noise.
Stress, fatigue, caffeine, tobacco and alcohol are non-auditory factors that influence the occurrence and severity of tinnitus. Cochlear evaluation include: pure tone audiometry, auditory brain stem response, speech audiometry, tone decay testing and tests for recruitment. The term ABC denotes aurium (one ear), binaural (two ears), and cerebri (centered in the head).
The stiffness of the stereocilia is altered causing its decoupling from the tectorial membrane. This indicates that tinnitus could be generated by the brain in response to lack of normal stimuli from the auditory system.
This type of tinnitus occur due to irritation to the nerve by the offending vessel (kindling phenomenon). This type of hallucinations occur in patients with psychiatric disorders like schizophrenia. Subjective tinnitus is usually high pitched and ringing in nature and can only be perceived by the patient. In Meniere's disease it is low frequency, while in noise indued tinnitus it is of high frequency. Measurments of tinnitus include assessment of the pitch, bandwidth, loudness, maskability of tinnitus and residual inhibition.
In tinnitus loudness match the patient is instructed to match the loudness of tinnitus with that of narrow band noise generated at about the same frequency as the tinnitus. This condition is often accompanied by hyper sensitivity to environmental sounds known as hyperacusis. Venous causes include benign intracranial hypertension, high jugular bulb and hydrocephalus.
These features are caused by changes in the function of nuclei in the ascending pathways, or by redirection of information to regions of CNS that normally donot receive inputs from the auditory system. Whereas objective tinnitus is commonly pulsatile in nature and is also heard by the examiner.
Hyperacusis is the condition where ordinary sounds are perceived as loud and uncomfortable.
The main advantage of this scheme is that the physician need to choose from only two options under each descriptive category.
A single pure tone masking tone of any frequency may mask a broad band spectrum of tinnitus.
Later symptoms can include headache, stiffness of the neck, and tingling or numbness in the extremities. Bad plasticity causes hypersensitivity and hyperacitivity by redirecting information to other parts of central nervous system by unmasking dormant synapses.
It has also been suggested that phase locking of the activity in many nerve fibers can also be a cause for tinnitus.
