Sensorineural hearing losses occur when the "inner" ear or the actual hearing nerve itself becomes damaged. Sensorineural hearing loss is often referred to as "nerve deafness." Nerve deafness is not really an accurate description because the damage most frequently occurs within the inner ear rather than the hearing nerve.
An impaired cochlear perfusion seems to be an important etiopathogenetic event in idiopathic sudden sensorineural hearing loss (ISSNHL).

RESULTS: We found 45 articles, 15 of these made up the study by fitting either the inclusion factors. CONCLUSION: VEMP may be useful as hearing recovery predictor in patients with sudden sensorineural hearing loss, justifying the implementation of such examination in this population. Sudden sensorineural hearing loss or sudden deafness is characterized as a hearing loss of abrupt onset, usually unilateral, with no known cause. It's an emergency in otology and affects mainly the fourth decade of life and affects 5 to 20 people out of 100 thousand individuals per year and it is estimated that there are about 4000 new cases per year in the United States and 15,000 worldwide, with equal distribution in relation to gender4-6. They are hypotheses to explain the etiology of sudden deafness as the vascular hypothesis, viral hypothesis, the autoimmune hypothesis and the membrane rupture hypothesis. The Vestibular Evoked Myogenic Potential is an electrophysiological test that evaluates the goal via spinal hall. The history of this examination is relatively recent as though their first date back to 1964 reports, only in 1994 were published the first studies suggesting clinical application for Evoked Myogenic.
For review of the vestibular pathway that cannot be analyzed by the other entrance exams, the exam has been gaining attention in the labial battery evaluation. The aim of this study was to investigate the clinical applicability of Vestibular Evoked Myogenic Potentials in patients with sudden sensorineural hearing loss.
This is a systematic review that followed the precepts of the Cochrane Handbook11 as the formulation of the question, location, selection and critical evaluation of the articles. Using the extracted descriptors of Medical Subject Headings (MeSH), was established the following advanced search strategy in PubMed, 'vestibular evoked myogenic potentials' associated by the Boolean operator AND to 'hearing loss, sudden'.
In the LILACS and SciELO database, we used the indexed descriptors Descriptors in Health Sciences (MeSH), according to the following strategy: Perda auditiva subita AND Potenciais evocados.
It was considered as inclusion criteria articles in English, Portuguese or Spanish, published in the last two decades that associate sudden sensorineural hearing loss and vestibular evoked myogenic potentials. Abstracts of pre-selected articles were assessed by two reviewers, were selected for analysis those correlated descriptors. Data were tabulated covering the following information: authors, place and year of publication, sample size (n), objectives and type of study (Table 1). The 45 articles found, 11 were excluded due to language, to be present at duplicate or not correlate the descriptors. About the type of study 53% were prospective, 6 longitudinal studies10,12-16 and two transverse17,18, 33% were restrospectives19-23, 7% case study24 and 7% Bayesian cure rate model25.


The objective of 60% of the studies was to determine whether the Vestibular Evoked Myogenic Potential (VEMP) can be used as a predictor of hearing recovery in patients with PANSS10,12-16,19,20,23. Among the studies that have investigated the use of objective tests in the management of patients with PANSS some noteworthy.
Study conducted in Japan, with 22 patients with PANSS and single episode of vertigo, revealed that 77% and 45% showed VEMP and caloric test changed, respectively.
Prognostic factors of patients with PANSS and worse hearing threshold than 70 dB, and its relationship with hearing and vestibular tests were investigated. Trying to minimize the uncertainties surrounding the hearing recovery of patients with sudden sensorineural hearing loss was developed a predictive model of evolution by reference audiological tests (audiometry, DPOAE, VEMP and ABR) and other variables considered as prognostic factors.
Many studies have sought to elucidate whether the Vestibular Evoked Myogenic Potential can be a useful predictor of hearing recovery in patients with sudden sensorineural hearing loss, which is a positive relationship in most of them, justifying the implementation of such examination in this population. Paper submitted to the ITJ-SGP (Publishing Management System) on December 21, 2014; and accepted on March 19, 2015. The white area represents the sounds that the person would not hear (softer then their thresholds) and the tan area indicates all of the sounds that the person would be able to hear (louder then their thresholds). About 90% of all people with hearing impairment are in this category, making it the most common type of hearing impairment. The truth is that most people never do anything with the products they buy, so most of the time, they dona€™t get ANY results. Vestibular evoked myogenic potential (VEMP) estimates of the vestibular pathway that can not be analyzed by the other entrance examinations, which can be helpful in diagnosing the extent of hearing damage in these patients. However, the current trend is to consider the sudden hearing loss as a disease of multifactorial etiology1. The eliciting stimulus can be audible (click) or galvanic, activating the saccular macula and triggering the reflex pathway lowest labial nerve, lateral vestibular nucleus, spinal tract hall and finally ipsilateral motor neuron, being picked up by surface electrodes arranged on the sternocleidomastoid muscle7,8. Despite this, few studies have been published focusing on the Vestibular Evoked Myogenic Potential in inner ear disorders such as sudden deafness10. Of these, 67% found a positive relationship between the presence of VEMP and the degree of hearing recovery10,13,15,19,20,23. The authors suggest that the sacculus is most often struck in the case of the PANSS the horizontal semicircular canal function and its afferent.
VEMP and ABR were positively correlated with a better prognosis, reaching 64% of full recovery in patients with hearing severe hearing loss20. The authors conclude that this is a useful method, however, point out that should only be used if the therapy used is the same adopted in the study25. Among patients with recurrent ipsilaterally PANSS, all had normal VEMP and had hearing recovery.

Thus, "sensorineural" indicates the part of the ear that is malfunctioning and encompasses many different causes for the malfunction.
This observational study aimed to evaluate the possible role of oxidative stress in ISSNHL.


Currently its route and method are well defined and the latter studies devoted to clinical applications9. Of these, 15 articles were included in the study by fitting either the inclusion factors (Table 2). Others studies despite having different objectives pointed VEMP as helpful tool in the management of patients with sudden sensorineural hearing loss17,18,21,22,25. They add that the creation of the VEMP associated with caloric test is useful in the evaluation of these patients as they relate to the degree of hearing recovery23.
Since patients with contralateral applicant PANSS, 80% had altered VEMP, showing no hearing recovery after treatment. Ocular vestibular evoked myogenic potentials induced by bone-conducted vibration in patients with unilateral inner ear disease. Subjective visual vertical perception in patients with vestibular neuritis and sudden sensorineural hearing loss. Distortion product otoacoustic emissions as a prognostic factor for idiopathic sudden sensorineural hearing loss. Saccular damage in patients with idiopathic sudden sensorineural hearing loss without vertigo. Three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging in sudden sensorineural hearing loss: correlations with audiologic and vestibular testing.
Correlation between audiovestibular function tests and hearing outcomes in severe to profound sudden sensorineural hearing loss. Difference in the nature of dizziness between vestibular neuritis and sudden sensorineural hearing loss with vertigo. Abnormal vestibular evoked myogenic potentials in the presence of normal caloric responses.

The testimonials you see on this web site are some of our better results and are not typical.
It was concluded that VEMP can be used as a prognostic factor in recurrent PANSS in order that their presence would indicate a high probability of hearing recovery19. They stuck to the dose as directed and maintained a healthy lifestyle and balanced diet alongside it.
However, most people with sensorineural loss find wearing hearing aids to be of significant benefit and some people with severe loss can benefit from a cochlear implant. Moreover, a global oxidative stress index (Oxidative-INDEX), reflecting both oxidative and antioxidant counterparts, was also calculated. As oxidative stress is a key determinant in endothelial dysfunction, our findings could suggest vascular impairment involvement in ISSNHL etiopathogenesis.
