Cervical osteochondrosis in Meniere’s disease

V.K. Pinchuk describes, with deforming spondylosis of the cervical spine, the posterior cervical sympathetic syndrome, in which, unlike Meniere’s disease, there is a slight and inconsistent hearing loss, intense pain in the cervical-occipital region, and there is no nystagmus and Romberg symptom. V. I. Aslamazova examined 69 patients with cervical osteochondrosis and came to the conclusion that the load on the spine increases the thresholds of perception by 10-20 dB, which is not normal in Meniere’s disease. E.I. Petrova, V.P. Prokhorov in 23 patients with Meniere’s disease revealed hearing loss according to the type of disturbance in sound perception. In 19 of them, the phenomenon of accelerated increase in volume was positive. In all patients, the differential threshold is lowered, and the perception of ultrasound is normal, with most of the lateralization in a better hearing ear; speech intelligibility is reduced on the affected side. V. N. Prokhorov, N. S. Martynova, examining 50 patients with Meniere’s disease and 50 patients with cohleove-stibulopathy and cervical osteochondrosis, found that patients with cochleovestibulopathy and cervical osteochondrosis have bilateral ear damage and “secondary cochlear neuritis” in 74% of cases that must be taken into account during differential diagnosis. Decher considers the presence of a flat (horizontal) audiogram and the study of all semicircular canals important in the differential diagnosis of Meniere’s disease. With cervical-basilar insufficiency, turns of the head and load on the spine alter hearing acuity. K. B. Radugin, L. P. Ryzhkov, K. B. Radugin et al. Based on the results of the examination, 50 patients established a parallelism between hearing in the low zone (60–70 Hz) and sensitivity to ultrasound, as well as between auditory and vestibular disorders. Z. I. Munchaev et al. 50 patients underwent rheoencephalography, tonal, threshold and suprathreshold audiometry, lateralization of ultrasound, cupulometry using the Egmond – Schuknecht technique and found that the cochlear and ampullar parts of the labyrinth are affected first, and the vestibule sacs are the last. A characteristic feature of the peripheral lesion of the analyzer is vestibular recruitment. V. S. Olisov et al. believe that the conductive component of hearing loss in Meniere’s disease is due to two main reasons: hydropic changes in the labyrinth (they can block the labyrinth’s windows and reduce the amplitude of oscillation of the main membrane) and the hypertonicity of the muscles of the tympanic cavity. Nadol found a positive Henibert test in 24 of 81 patients with Meniere’s disease, which indicates a pathological condition of the vestibule – the presence of adhesions of the membranes of the inner ear with stirrup. Some authors used additional diagnostic methods. N. A. Balkovskaya, using plethysmography, revealed that with Meniere’s disease, vascular reactions on the affected side are more pronounced than in healthy ones. Moreover, they are pressor and depressive, and with repeated studies may change. Conditional (on a call) vascular reactions are more difficult to develop, they are inconsistent and weakly expressed.
