LABYRINTHOPATHY (labyrinthopathia; grech, labyrinthos a labyrinth + pathos suffering, a disease) — the term for a symbol of diseases of an inner ear of noninflammatory character which are shown by the peripheral slukhovestibulyarny frustration which are not keeping within a framework of the known nosological forms. Reasons of L. can be various. Quite often L. develops as a result of the combined influence of several factors: disturbances of a trophicity of a labyrinth in connection with change of blood supply and a vegetative innervation, toxic influence, disbolism in an organism. Standard classification of L. no. V. F. Undrits (1958) allocates primary idiopathic, genuinical L. (Menyer's disease) and secondary L., arising in connection with other diseases. I. M. Rosenfeld (1956) distinguishes L. idiopathic (or essential), toxic, vegetative, endocrine, vascular and timpanogenny. V. S. Olisov (1973) allocates acute L. (apoplektiformny, traumatic, infectious and toxic, vasculomotor forms) and chronic (remittiruyushchy — Menyer's disease, the erased form — labirintoz, postoperative L., position labyrinth syndrome). Most of other authors considers Menyer's disease an independent disease (see. Menyera disease ). Carry to labyrinthopathies also postoperative L. — damage of an inner ear as a result of a surgical injury at operations on a stirrup for an otosclerosis and at the sanifying and slukhovosstanavlivayushchy a middle ear operations at patients hron, purulent average otitis. However in connection with improvement of diagnosis in many cases need of use of the term «labyrinthopathy» disappears. In particular, thanks to carrying out otoskopiya (see) with use operative microscope (see) it is established that in some cases the slukhovestibulyarny frustration which appeared after operation on a stirrup can be result of a perilymphangeal fistula, postoperative granuloma, shift of a prosthesis in a threshold of an inner ear. At patients hron, purulent average otitis, undergone the sanifying ear operations and suffering hron, vestibular dysfunction, under a microscope the changes which are pathomorphologic substrate of an inflammation and testimonial of existence hron are found labyrinthitis (see). Thus, in these cases are possible specific to lay down. recommendations — audit and a reoperation on an ear the patient who transferred a stapedoplasty and radical a middle ear operation. These interventions quite often save the patient from the long, exhausting him vestibular dysfunction and prevent further damage of formations of an inner ear, a cut can lead to death of a labyrinth.

L. it is characterized by the progressing falling of hearing as disturbance of the sound perceiving device (see. Deafness ) and hron, the vestibular dysfunction which is periodically amplifying (dizziness, a nystagmus, nausea, vomiting).

In the presence of only acoustical frustration of not clear nature, but not inflammatory genesis sometimes use the term «cochleopathy».

Understand disorders of function only of a vestibular mechanism at some intoxications, vascular defeats, syphilis etc. as a vestibulopathy. Understand also bad portability as the term «vestibulopathy» the person of vestibular irritants since the childhood (a family vestibular syndrome, or an essential vestibulopathy).

The vestibulopathy should be differentiated with a so-called vestibular neyronit. This term is entered by Dix and Hollpayk (M. Dix, S. Hallpike, 1952). Mean the vestibular dysfunction which arose in connection with the postponed viral infection by it.

Treatment of L. symptomatic.
