Ear Disorders

At the Center for Cooperative Medicine, we are studying the effects of laser light at low intensity in ear disorders, including tinnitus, hearing loss and Meniere’s disease.

How effective is laser therapy?

In a study of 348 patients by Dr. Lutz Wilden, virtually everyone responded positively, and average hearing capacity increased by nearly 21%. The degree of improvement correlated with patients’ age and the duration of their condition. 1

Who may benefit?

Almost anyone with hearing loss, tinnitus, vertigo or other disorders related to the ear according to Dr. Wilden, who writes, “….even serious impairments such as the most excruciating cases of tinnitus, dysacusia, morbus Menière and bradyacusia can be considerably alleviated and even healed with the aid of modern light technology and the corresponding medical management.” 2

What is the nature of tinnitus, hearing loss and ear-related vertigo?

Tinnitus, the perception of sound without an external cause, is an emergency signal by cells in the inner ear according to Dr. Wilden. Just as placing pressure on the eyes with a finger causes one to see stars, so tinnitus may be the result of stress to the cells responsible for our sense of hearing in the inner ear.

In modern society background noise is omnipresent, often at high levels, and our sense of hearing has been universally challenged. Wilden believes that tinnitus, hearing loss, vertigo, and altered sensation within the ear are often the result of “biological exhaustion of the inner ear”, and this may be due to acute or chronic exposure to sound, antibiotics, other drugs and many other stressors.

Laser Therapy and Cochlear Hair Cells

Hair cells are our sensory receptors for sound.  Most hearing loss in humans is a result of damage to cochlear hair cells.  Two studies in 2011 and 2012 by Rhee et al  [3,4] reported that laser therapy stimulated the regeneration of hair cells.

In rats exposed to loud noise in the 2012 study and treated with laser therapy, the investigators found:

  1. An increase in the number of hair cells.
  2. A statistically significant reduction in hearing threshold laser treated ears.  Since hearing threshold is the point below which a sound becomes undetectable, a reduction in hearing threshold means improvement in the perception of that sound at a lower intensity.

In the 2011 study, the authors administered gentamicin, an antibiotic famously known to cause hearing loss in humans, to tissue cultures of rat cochlea (living cells from the cochlea of rats kept alive in a petrie dish or similar medium).  The number of hair cells was significantly greater in the gentamicin plus laser group than in the gentamicin only group. See the abstracts here.

How low intensity laser and pulsed electromagnetic field

therapies may help in hearing loss, tinnitus and ear-related vertigo

Think of laser therapy as a battery jump for cells.  See how it works here.

Acoustic and other trauma, including drugs and the aging process, may damage hair cells and other delicate structures within the cochlea, an important sound processing center in the inner ear, resulting in hearing loss.  Laser and pulsed electromagnetic field therapies have properties to stimulate biological function and regenerate tissue which may help re-establish normal transmission of nerve impulses.

Tinnitus is another frequent consequence in which nerves are stimulated to send impulses to the brain perceived as sound but without an external cause. Laser and pulsed electromagnetic field therapies have been documented to regenerate nerve, restore hearing and reduce middle and inner ear inflammation, and they may even help to reverse ankylosis, the fusion of the tiny bones within the ear which may occur with aging.

What is treatment like?

Laser therapy may be administered  directly into the ear while one is lying comfortably in a darkened room. For most individuals, most of the time, treatment is quite comfortable. Many fall asleep. One may experience mild warmth from the laser diodes within each ear.  Pulsed electromagnetic field therapy may also be given simultaneously.

Over a course of treatment, the volume of tinnitus may increase, and its pitch may change. Some experience sensitivity to sound, pressure or other sensations. Yet these may be considered signs that treatment is working. Wilden writes, “First the patients experience an amelioration of their hearing capacity. Then the symptoms sensation of pressure in the ear and vertigo improve, and finally the ringing in the ears (= tinnitus) changes its property; having first become unsteady in volume, tone quality and frequency (which often gets higher and higher) and more easily assignable to corresponding stressors, it gradually thins down and recedes further and further into the background, until it eventually disappears for good.” 5

How many treatments will be necessary?

This depends upon the nature, degree and duration of the condition. Generally, acute conditions and younger patients respond more quickly. Long-standing, chronic conditions and older patients may require more treatment. The longer someone has been experiencing tinnitus, hearing loss or ear-related vertigo, the greater the time and laser energy likely to be necessary. Yet although there are no panaceas or guarantees, Dr. Wilden also notes, “After thirty years of experimental and clinical research, there aren’t any known side-effects of low level laser light.”6
