RINNE EXPERIENCE

From Big Medical Encyclopedia

RINNE EXPERIENCE (H. A. Rinne, is mute. the otolaryngologist, 1819 — 1868) — one of methods of definition of localization of pathological process in an ear consisting in comparison of duration of acoustical perception of sounding of a tuning fork at bone and air conductivity. It is offered in 1855 Mr. of Rinne. In R.'s practice by the lake it was implemented in 1880 after to Lyutsa (L. J. Page of Lucae) showed its importance for a functional research of hearing.

For carrying out experience use tuning forks of rather low tonality (more often than 128, 256 fluctuations in sec.). The tuning fork given to sounding is established by a leg on a mastoid of a pyramid of a temporal bone. When investigated ceases to hear sounding of the tuning fork put on a mastoid (the end of perception of tone at bone conductivity), branches of a tuning fork bring directly to an entrance to outside acoustical pass and measure duration of perception of tone at air conductivity. Normal duration of perception of a sound of a tuning fork at air conductivity exceeds duration of perception it at bone conductivity. In this case designate result of experience — «positive» (R +). If there is a defeat of the sound carrying out system (an otosclerosis, hron. average purulent otitis, etc.), perception of a sound of a tuning fork at bone conductivity is longer, chekhm at air conductivity. In this case the result of experience is designated as «negative» (R —). If perception of a sound of a tuning fork at bone and air conductivity is identical on time, then the result of experience is designated (Р±). At diseases of an inner ear of R. the island is positive, as well as is normal, but differs in considerable shortening of sounding of a tuning fork at bone and air conductivity (small positive R. of the lake).
