“…We can see that from the entire group with remission, 50% that had partial improvement and 30% that had no improvement had been submitted to ear surgeries. These cases portray one of the most satisfactory results of VR, that the earlier it is started, the more benefit it will provide in terms of therapeutic results 15 .…”

A reabilitação vestibular (RV) é uma ótima opção terapêutica para tratamento dos pacientes vestibulopatas. Contudo, mesmo quando bem conduzida, algumas vezes não surte os efeitos propostos. OBJETIVO: Avaliar a resposta de pacientes submetidos à RV em relação às etiologias apresentadas. Forma de Estudo: Retrospectivo descritivo. PACIENTES E MÉTODO: Analisamos pacientes que concluíram a RV e tinham diagnóstico entre janeiro de 2002 e dezembro de 2004. Dividimos os pacientes em três grupos, de acordo com a resposta à RV e os comparamos em relação às etiologias. RESULTADOS: Observamos 13 casos sem melhora com a RV, 24 com melhora parcial e 22 com remissão dos sintomas. As etiologias encontradas foram cervical, trauma, metabólica, central, transtornos da ansiedade e do humor, doença auto-imune, intolerância ortostática. A etiologia metabólica apresentou evolução significativamente melhor do que as demais. CONCLUSÃO: Quando associada à adequada correção etiológica, a RV é uma ótima opção no tratamento das vestibulopatias.

“…Our findings provide information that may be useful in the development of novel rehabilitation methods that take advantage of the convergence of sensory inputs and motor signals contributing to the early and late stages of compensation. For example, there is evidence for (Herdman et al 1995) and against (Cohen and Kimball 2002;Mruzek et al 1995) the use of rehabilitation exercises that are specifically focused on neck movements, and therefore involve the activation of neck proprioceptors, in the acute stage after injuries. We showed that during vestibular compensation changes in convergent multiple sensory inputs and different signals occur at the early and late stages of compensation.…”

Sadeghi SG, Minor LB, Cullen KE. Multimodal integration after unilateral labyrinthine lesion: single vestibular nuclei neuron responses and implications for postural compensation. J Neurophysiol 105: 661-673, 2011. First published December 8, 2010 doi:10.1152/jn.00788.2010. Plasticity in neuronal responses is necessary for compensation following brain lesions and adaptation to new conditions and motor learning. In a previous study, we showed that compensatory changes in the vestibuloocular reflex (VOR) following unilateral vestibular loss were characterized by dynamic reweighting of inputs from vestibular and extravestibular modalities at the level of single neurons that constitute the first central stage of VOR signal processing. Here, we studied another class of neurons, i.e., the vestibular-only neurons, in the vestibular nuclei that mediate vestibulospinal reflexes and provide information for higher brain areas. We investigated changes in the relative contribution of vestibular, neck proprioceptive, and efference copy signals in the response of these neurons during compensation after contralateral vestibular loss in Macaca mulata monkeys. We show that the time course of recovery of vestibular sensitivity of neurons corresponds with that of lower extremity muscle and tendon reflexes reported in previous studies. More important, we found that information from neck proprioceptors, which did not influence neuronal responses before the lesion, were unmasked after lesion. Such inputs influenced the early stages of the compensation process evidenced by faster and more substantial recovery of the resting discharge in proprioceptive-sensitive neurons. Interestingly, unlike our previous study of VOR interneurons, the improvement in the sensitivity of the two groups of neurons did not show any difference in the early or late stages after lesion. Finally, neuronal responses during active head movements were not different before and after lesion and were attenuated relative to passive movements over the course of recovery, similar to that observed in control conditions. Comparison of compensatory changes observed in the vestibuloocular and vestibulospinal pathways provides evidence for similarities and differences between the two classes of neurons that mediate these pathways at the functional and cellular levels.

“…Vestibular rehabilitation is the gold standard to achieve vestibular compensation. 40 Facial nerve palsy can be treated by physical rehabilitation, 41 or using surgical procedure in inveterate case. [42][43][44][45] Residual hearing loss is successfully treated using temporal bone anchorage device.…”

PubMed and Google Scholar searches using the following keywords: arachnoid cyst, internal auditory canal, temporal bones study, schwannoma of internal auditory canal, cystic schwannoma, MRI findings, surgery of internal auditory canal. Only the article where three keywords, included always arachnoid cyst, were considered. The study analyzed the etiopathogenesis of arachnoid cyst, hearing and vestibular symptoms and temporal bone findings. Review and conclusion: The author identified and reviewed a total of 46 articles. The results showed high incidence of hearing loss that was the more common symptom than vestibular one. Arachnoid cyst carried out more compression on the vestibular nerves than on the cochlear one. The review allowed us to identify which mechanism of damage arachnoid cyst acting on the nerves. It is necessary to consider the arachnoids cyst in differential diagnosis with tumors and pathologies involving the internal auditory canal.
