Effective Management of Ménière's and Vestibular Disorders with Photo‐Biostimulation Light Laser

Abstract

Objectives: Laser irradiation applied inside the inner ear has been investigated to observe the therapeutic effectiveness in cochlear injury and vestibular dysfunction. The positive influence of light irradiation with low level laser therapy on the treatment of vascular disorders, ischemic arteriolar disease, activation of microcirculation, and tissue regeneration is well known and has been published by several authors from medical research groups. The aim of this study was to determine the effects and benefits for patients with Ménière’s disease and other vestibulopathies who received an irradiation dose into the inner ear by using a protocol of irradiation. Methods: A laser device with double wavelength and independent light beams was used to irradiate through the ear canal with power irradiance of 90 to 300 mw/cm2 at different dose rate according to patient symptoms. A prospective study of a group of sixty five (65) patients who were suffering peripheral vestibular disorder were treated from January 2010 to July 2011 in a random selection with no exclusions for other pathologies. Method of irradiation was direct beam over “meatus acusticus” at 1.5 cm distance of ear drum membrane. Results: Fifty patients of the 65 were considered final group control. According to American Academy of Otolaryngology—Head and Neck Surgery guideline criteria, 64% were classified as Category A on their vertigo management and 36% were Category A+B. After the treatment period, both categories confirmed that crises were shorter, less severe and with lower intensity. Conclusions: Laser irradiation has no risk for patients and can be considered both effective and an alternative therapy.
