What is Meniere's disease?
Meniere's disease is an idiopathic inner ear disease, formerly known as Meniere's disease, first proposed by the French physician Prosper Ménière in 1861. The main pathological change of the disease is hydrocephalus, and the clinical manifestations are recurrent spine vertigo, fluctuating hearing loss, tinnitus and ear swell. The disease occurs mostly in middle and young people between the ages of 30 and 50, and children are rare. There is no significant difference between men and women. Children with both ears account for 10% to 50%
Cause:
Various infection factors (bacteria, viruses, etc.), injuries (including mechanical or acoustic damage), otosclerosis, syphilis, genetic factors, allergies, tumors, leukemia and autoimmune diseases.
Clinical manifestations:
1.Dizziness
2.Deafness
3. Tinnitus
4. Ear swell
Low-level laser therapy for tinnitus:
Description :
LLLT is non-invasive, painless and can be easily administered in primary care settings. LLLT acts by inducing a photochemical reaction in the cell, a process referred to as biostimulation. It is an irradiation technique that has the ability to induce biological processes using photon energy. There are studies showing proliferation and angiogenesis. Most evidence of efficacy is based on the increase in energy state and the activation ofmitochondrial pathways. It has been reasonably well established that mitochondria are a principal intracellular target of red and near infrared light. In recent years, LLLT has been widely used in the treatment of tinnitus. These laser beams are cool to the touch and do not cause discomfort. They are aimed into the auditory canal and through the mastoid bone behind the ear. The wavelength nature of these lasers allows them to penetrate tissue.
How is work:
The prevailing opinion is that the respiratory chain plays a central role in the effect induced by laser therapy. Laser energy in the red and near infrared light spectrum is capable of penetrating tissue. It stimulates mitochondria in the cells to produce energy through the production of adenosine triphosphate (ATP). Mitochondria are the power supplies of all cells; they metabolise fuel and produce energy for the cell in the form of ATP. It has been reported that LLLT irradiation increases the production of ATP. Increased ATP production may lead to enhanced cell metabolism, promoting the damage recovery process, returning cells to a healthy state and reversing many degenerative conditions. For ear disorders, low-level laser has been reported to alter the collagen organisation within the cochlea, especially within the basilar membrane. Also, LLLT has a beneficial effect on the recovery of cochlear hair cells after acute hair cell loss, increases cell proliferation, synthesis of ATP and collagen, release of growth factors, promotes local blood flow in the inner ear and activates repair mechanisms in the inner ear through photochemical and photophysical stimulation of the hair cell mitochondria.
