[Response of spiral organ cells on laser radiation to the region of tympanic graft (experimental study].
Spiral organ cells ultrastructure was studied electron microscopically after exposure to high-energy NIAG-Nd-laser radiation in contactless impulse regimen (1.06 microns, 20-40 W, 100 microseconds) in experimental tympanoplasty. The above laser radiation did not entail gross destruction in receptor and pillar cells in the peripheral compartment of the organ of hearing. Irrespective of the radiation power 3 days after the exposure some irradiated receptor cells showed insignificant changes: mitochondrial vacuolization, altered cuticular plate. 7 days after the exposure a positive response was registered in the majority of the receptor cells and in some pillar cells. This reflects activization of intracelluler biosynthetic processes.
