1. Application of Cervical Vestibular-Evoked Myogenic Potentials in Adults with Moderate to Profound Sensorineural Hearing Loss: A Preliminary Study
Abstract Introduction The cochlea and the vestibular receptors are closely related in terms of anatomy and phylogeny. Patients with moderate to profound sensorineural hearing loss (MPSHL) should have their vestibular organ functions tested. Objective To evaluate the incidence of vestibular abnormalities in patients with MPSHL and to study the correlation

2. Cochlear implant revision surgeries in children
Resumo Introdução: A cirurgia para a implantação do dispositivo interno do implante coclear não é inteiramente livre de riscos e pode apresentar problemas que exigem cirurgias revisionais. Objetivo: Verificar a incidência das indicações de cirurgias revisionais para a implantação do dispositivo interno do implante coclear, sua efetividade e corr

3. The Relationship between the Etiology of Profound Prelingual Sensorineural Hearing Loss and the Results of Vestibular-Evoked Myogenic Potentials
Abstract Introduction Cervical vestibular-evoked myogenic potentials (cVEMPs) are biphasic, short latency potentials, which represent the inhibition of the contraction of the sternocleidomastoid muscle (SCM) mediated by the saccule, the inferior vestibular nerve, the vestibular nuclei and the medial vestibular spinal tract. Objective To evaluate the resp

4. Sudden Sensorioneural Hearing Loss and Autoimmune Systemic Diseases
Abstract Introduction Several authors have demonstrated the relationship between sudden sensorineural hearing loss (SNHL) and systemic autoimmune diseases (SAD). Immunemediated SNHL can rarely present as unilateral sudden SNHL and manifests itself in the contralateral ear only after years. It presents clinical relevance for being one of the few SNHL that m

5. Adenomatous Tumors of the Middle Ear: A Literature Review
Abstract Introduction Neuroendocrine adenomas of the middle ear (NAME) are uncommon causes of middle ear masses. Mostly limited to case reports and small series, the literature is poor in providing an overall assessment of these tumors. Objective To review the current literature about all aspects of the disease, including its etiology, clinical manifesta

6. Auditory Speech Perception Tests in Relation to the Coding Strategy in Cochlear Implant
Abstract Introduction The objective of the evaluation of auditory perception of cochlear implant users is to determine how the acoustic signal is processed, leading to the recognition and understanding of sound. Objective To investigate the differences in the process of auditory speech perception in individuals with postlingual hearing loss wearing a coc

7. Auditory Neuropathy/Dyssynchrony: A Retrospective Analysis of 15 Cases
Introduction Auditory neuropathy/dyssynchrony (AN/AD) comprises a spectrum of pathology affecting the auditory pathways anywhere from the inner hair cells to the brainstem. It is characterized by an absent or atypical auditory brainstem response (ABR) with preservation of the cochlear microphonics and/or otoacoustic emissions (OAEs).

8. Screening of Connexin 26 in Nonsyndromic Hearing Loss
Introduction The first locus for nonsyndromic autosomal recessive hearing loss is on chromosome 13q11-22. The 35delGmutation is present in 80% of cases in which GJB2 is involved, which makes the study of this mutation very important. The viability and benefits of screening for mutations in the connexin 26 gene are now beginning to chan

9. Epidemiology of Intratemporal Complications of Otitis Media
Introduction Despite the advent of antibiotics and immunizations in the last century, complications of otitis media remain quite frequent, have high morbidity and mortality rates, and pose a challenge to the otorhinolaryngologist. Objective To establish the annual incidence of intratemporal complications of otitis media and prospectively evaluate patien

10. Longitudinal Analysis of the Absence of Intraoperative Neural Response Telemetry in Children using Cochlear Implants
Introduction Currently the cochlear implant allows access to sounds in individuals with profound hearing loss. The objective methods used to verify the integrity of the cochlear device and the electrophysiologic response of users have noted these improvements. Objective To establish whether the evoked compound action potential of the auditory nerve can ap

11. Contribution of audiovestibular tests to the topographic diagnosis of sudden deafness
INTRODUCTION: Sudden hearing loss (SHL) is an ENT emergency defined as sensorineural hearing loss (SNHL) > 30 dB HL affecting at least 3 consecutive tonal frequencies, showing a sudden onset, and occurring within 3 days. In cases of SHL, a detailed investigation should be performed in order to determine the etiology and provide the best treatment. Otoacousti

12. Estudo da etiologia da perda auditiva em amostra de individuos brasileiros : diretrizes para protocolo de conduta clínica / Study of the etiology of hearing loss in a sample of brazilian individuals : guidelines for clinical management protocol
Deafness is considered the most prevalent sensory disorder in humans, caused by a variety of environmental and genetics factors. In Brazil, there are no official data regarding the prevalence and etiology of hearing impairment, but it is known that environmental factors are among the major causes. Although a simultaneous testing approach, including clinical
