Problems of defect hearing or diseases of particular parts of the ears appear from various causes. The most severe cases relate to middle and inner parts of the ear. Besides other treatments, this is also treated by laser beams. This invention relates to conducting a laser light beam from a source outside the ear directly to the middle and the inner ears, aimed to as efficient and quick as possible healing such disturbances as ringing in the ears, loss of hearing, Ménières disease, vertigo, inflammations, etc. Presently, illuminating of the middle and the inner ears is performed from outside, by directing a laser light beam of large power through the bone. This results in large losses in light power reaching the intended spot. The invention essence is the light-conducting earmold provided with an optical fiber. The light-conducting earmolds is custom made according to a patients ear canal model, or in series as a generic earmold. Through the light-conducting earmold passes an optical fiber conducting the laser light beam. To the optical fiber in the light-conducting earmold is connected a laser light source. During the treatment session the patient does not have to lie down and still. The light beam passes through the optical fiber and the light-conducting earmold, passing directly through the eardrum into the middle and the inner ears. Direct acting of the laser beams on parts of the middle and the inner ears decreases losses and requires lesser laser light of lesser power.Des problèmes daudition défectueuse ou des maladies de parties particulières des oreilles apparaissent provenant de différentes causes. Les cas les plus graves concernent des parties moyenne et interne de loreille. En plus dautres traitements, ceux-ci sont également traités par des faisceaux laser.
