Hearing loss with prescription of cervical osteochondrosis from 5 to 10 years

Analyzing the changes in the perception of PTSD in people with a disease duration from 5 to 10 years, we divided them into groups according to the degree of asymmetry of auditory dysfunction. Clinical practice indicates that if in the early stages of the disease with unilateral lesions of the cervical spine, a clear unilateral hearing loss is determined (in remission), then with an increase in the duration of the disease to 5 years or more, even if unilateral neurological symptoms persist, the hearing loss begins to acquire bilateral character. With a thorough examination of such a patient, it is always possible to identify certain changes from the side of a healthy ear. This is especially true for the test for determining the sensitivity to perception of the HDTC, with which you can catch changes in a better-hearing ear. The use of other tests during this period is still ineffective. After 5-6 years from the onset of the disease, using methods such as the study of UHFH, it is also possible to obtain certain information about the functional state of the auditory analyzer. If in the initial stage of the disease in the phase of remission there is a tendency to lateralization of high-frequency sound to a healthy ear only at certain frequencies with normal rates of the UHF test, then people with a disease history of more than 5 years already have a distinct lateralization of PTSD and ultrasound in a healthy ear, persistent increase in UHF in both ears (especially in the affected ear), severe hearing loss up to deafness in tones with a frequency of more than 2000-3000 Hz, whispering and speaking on the affected side and hearing loss of varying degrees for these p to providers on the so-called healthy ear. In cervical osteochondrosis with vertebral artery syndrome, the phenomena of contralateral cochleopathy are significantly more pronounced than in Meniere’s disease. During the attack, against the background of pronounced central neurological disorders, vestibulo-vegetative syndrome, dizziness, often accompanied by spontaneous nystagmus, the lateralization of the HDTV in the affected ear remains, but subjectively its severity is significantly inferior to that in the period of remission. Not so pronounced is the phenomenon of “listening” with a healthy ear to high-frequency sounds when trying to study a sick ear. All this indicates that during a seizure, a healthy ear is also involved in the process. It is noteworthy that the lateralization of ultrasound in a healthy ear is preserved, and the range of low frequencies of perceived sounds is reduced. When analyzing the indicated dynamics of perception of low, high and ultra-high frequencies, the impression is made that, unlike Meniere’s disease, two pathogenetic processes occur in the auditory analyzer in CHF in the auditory analyzer: primary degenerative processes in the auditory receptors and central formations supplied by the vertebral artery system, and secondary mechanisms associated with a violation of homeostasis in the liquid labyrinth media. This, in particular, is evidenced by such facts as an early violation of the perception of high-frequency sounds by a sick ear, the phenomenon of lateralization of ultrasound into a healthy ear, a narrowing of the range of perception of low-frequency tones, and also the form of tonal audiograms. This question, however, requires further clinical and experimental development. With bilateral hearing loss in people with a disease of 5 to 10 years in remission, most often there is a sharp increase in thresholds at frequencies of 16,000, 14,000 and 12,000 Hz with air and bone conduction of sound or a complete lack of perception of some of these frequencies, starting with the maximum. During the attack period, asymmetric involvement of the labyrinths in the process is most often observed, even with a bilateral attack. One of the labyrinths is almost always in a more pessimal state, which is determined using not only acoustic but also vestibular tests: the prevalence of spontaneous nystagmus towards a more excited labyrinth, the asymmetry of the induced vestibular responses. During this period, as a rule, hearing in one ear decreases, noise appears in it, and thresholds for the perception of sounds at frequencies of 3000-6000 Hz increase. UHF on this ear is shifting to the rightup to 60–80 Hz, ultrasound is lateralized in the better hearing ear. Inconsistent data were obtained in the study of the perception of HDTV: in 70% of cases, lateralization of sound was observed in the worse hearing ear and in 30% in the better hearing ear. As a rule, if a sound of the same frequency is lateralized into a better hearing ear, then the sound of the same frequency is not perceived worse by the hearing ear. This phenomenon is observed in a clinically marked labyrinth crisis with a predominance of cerebral vascular component. Probably, this phenomenon can also be caused by the “terminal state” of a certain group of receptor cells on the side of the worse hearing ear, responsible for perceiving the frequency of lateralizing sound.
