[Mathematical modeling of laser-induced selective destruction of labyrinthine vestibular receptors].
Basing on mathematical modeling, we tried to investigate in humans the ability of laser energy to suppress the function of the ampullar receptors of the semicircular canels and otolith receptors; to elicit mechanism of action of laser energy on labyrinthine receptors. Modeling has shown that in 1 mm thickness of the canal wall laser impact raises temperature of the liquid to 120 degrees C. Temperature higher than 100 degrees C stands in it up to 120 ms. This induces a distinct hydrodynamic shock which suppresses function of labyrinthine ampullar and otolith receptors. The heat factor of the laser impact causes destruction of the receptor sensory cells lasting for about a year.
