[Effects of helium-neon laser energy on the tissues of the middle ear in the presence of biological fluids and drug solutions].
By means of biophotometry the coefficients of absorption and penetration depth of helium-neon laser radiation with a wavelength of 632.8 nm were measured. Measurements were made in the inflammatory mucous membrane of the tympanic cavity, mucous membrane of the tympanic-cavity infiltrated with the saline solution, cortical bone of the mastoid, cartilage of the auricle, blood, serum, exudate, 0.02% furacillin, 3% boric acid, 0.9% and 10% NaCl. These observations were used to develop an efficient method of laser therapy of the inflammatory and wound surface of the middle ear biological tissue, which formed the basis of a new procedure of the laser treatment of "closed" cavities of the middle ear in an early postoperative period after debridement or hearing repair surgery of suppurative otitis media which were filled with a transparent antiseptic solution.
