Application of argon laser to the inner ear. 1988

The effects of argon laser irradiation on the inner ear were studied morphologically. The stria vascularis showed focal coagulation, vesicle formation, perforation and atrophy after irradiation through the otic capsule. These changes vary according to the power and duration of irradiation. Atrophy of the stria vascularis can be produced without injuring the organ of Corti, by suitable application of the laser beam. The round window membrane transmits the argon laser. Tissues in the hook region and a part of the lower basal turn demonstrated changes of varying degree. Loss of the nerve fibres was observed in the osseous spiral lamina, which was fractured and dislocated. Irradiation through the stapedectomized oval window destroyed the macula sacculi without rupturing the saccular wall.

UI MeSH Term Description Entries
D007834 Lasers An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

D003051 Cochlea The part of the inner ear (LABYRINTH) that is concerned with hearing. It forms the anterior part of the labyrinth, as a snail-like structure that is situated almost horizontally anterior to the VESTIBULAR LABYRINTH. Cochleas
D006168 Guinea Pigs A common name used for the genus Cavia. The most common species is Cavia porcellus which is the domesticated guinea pig used for pets and biomedical research. Cavia,Cavia porcellus,Guinea Pig,Pig, Guinea,Pigs, Guinea
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D000882 Haplorhini A suborder of PRIMATES consisting of six families: CEBIDAE (some New World monkeys), ATELIDAE (some New World monkeys), CERCOPITHECIDAE (Old World monkeys), HYLOBATIDAE (gibbons and siamangs), CALLITRICHINAE (marmosets and tamarins), and HOMINIDAE (humans and great apes). Anthropoidea,Monkeys,Anthropoids,Monkey
D001128 Argon A noble gas with the atomic symbol Ar, atomic number 18, and atomic weight 39.948. It is used in fluorescent tubes and wherever an inert atmosphere is desired and nitrogen cannot be used. Argon-40,Argon 40
D013316 Stria Vascularis A layer of stratified EPITHELIUM forming the endolymphatic border of the cochlear duct at the lateral wall of the cochlea. Stria vascularis contains primarily three cell types (marginal, intermediate, and basal), and capillaries. The marginal cells directly facing the ENDOLYMPH are important in producing ion gradients and endochoclear potential. Vascularis, Stria
