What is tinnitus?

    Tinnitus represents one of the most elusive mysteries facing hearing health care professionals. Tinnitus refers to any auditory perception not directly produced by an external stimulus. It is commonly described as a hissing, roaring, ringing or whooshing sound in one or both ears, called tinnitus aurium, or in the head, called tinnitus cranii. The sound ranges from high to low pitch and can be a single tone, multi-tonal, or noise-like, having no tonal quality. Tinnitus may be constant, pulsing or intermittent. It may begin suddenly or progress gradually.

    Tinnitus can be broadly classified into two categories: objective and subjective.

Objective Tinnitus

    This form is audible to an observer either with a stethoscope or simply by listening in close proximity to the ear. Objective tinnitus accounts for less than 5 percent of overall tinnitus cases and is often associated with vascular or muscular disorders. The tinnitus is frequently described as pulsatile, or synchronous with the patient's heartbeat. In many instances, the cause of objective tinnitus can be determined and treatment, either medical or surgical, may be prescribed.

Subjective Tinnitus

    This form is audible only to the patient and is much more common, accounting for 95 percent of tinnitus cases. Subjective tinnitus is a symptom that is associated with practically every known ear disorder and is reported to be present in over 80 percent of individuals with sensorineural hearing loss, which is caused by nerve and/or hair cell damage.

    Because tinnitus, like pain, is subjective, two individuals may demonstrate identical tinnitus loudness and pitch matches yet be affected in significantly different ways. The severity of the tinnitus is largely a function of the individual's reaction to the condition. That said, many tinnitus sufferers:

• Have difficulty sleeping or concentrating

• Feel depressed or anxious

• Report additional problems at work or at home that may contribute to the distress caused by tinnitus

• Describe a correlation of tinnitus perception with stress

• It is often difficult to determine whether a patient's emotional state pre-existed, or is a result of the tinnitus.

Causes

    Although the exact mechanism underlying tinnitus is unknown, it is likely that there are many related factors. Tinnitus usually, but not always, has to do with an abnormality of the hearing or neural system.

There are a number of causes linked with tinnitus including:

• Disorders in the outer ear, such as ear wax, a hair touching the eardrum, a foreign body or a perforated eardrum

• Disorders in the middle ear, such as negative pressure from eustachian tube dysfunction, fluid, infection, otosclerosis, allergies or benign tumors

• Disorders in the inner ear, such as sensorineural hearing loss due to noise exposure, aging, inner ear infection or Meniere's disease often accompanied by hearing loss and dizziness

Tinnitus also can temporarily result from certain medications, such as:

• Anti-inflammatories such as aspirin, ibuprofen, nonsteroidal anti-inflammatories and quinine

• Sedatives

• Antidepressants

• Certain antibiotics and chemotherapeutic agents

Other causes include:

• Systemic disorders such as high or low blood pressure, anemia, diabetes, thyroid dysfunction, glucose metabolism abnormalities, vascular disorders, growth on jugular vein, acoustic tumors and head or neck aneurysms

• Non-auditory disorders such as trauma to the head or neck, temporomandibular (jaw joint) disorders and neck misalignment

    Current research suggests that even though tinnitus may initially be caused by an injury to the ear, ultimately an auditory pattern is established in the brain. Therefore, many treatment approaches are directed at the brain, not the ear.

    Although the majority of tinnitus sufferers also have hearing loss, the presence of tinnitus does not indicate that one is losing hearing.

Acupuncture treatment for tinnitus

    According to Chinese medicine theories, tinnitus is thought to be often caused by kidney deficiency and blood stagnation. The combination of acupoints such as Tai Chong, Tai Xi, Xia Guan, Yi Feng, Zhong Zhu and Xia Xi can stimulate and enhance the Qi and blood circulation along the meridians that connect the ears internally with Kidney. 

    Dr. Wang has successfully treated many patients with tinnitus. He has a special acupuncture technique to stimulate the point Yi Feng that is particularly effective for tinnitus. After many years of clinical practice, Dr. Wang has found that the proper depth of needling and the way to stimulate to induce Qi feeling at this point is crucial for the effectiveness. It usually takes a few treatments before improvement can be felt.  

    Tinnitus may not necessarily precede hearing loss, although some people have tinnitus, hearing loss and dizziness all together, which is usually seen in people with Meniere's disease.
