The neural response telemetry is used in order to measure the electrically evoked compound action potential of the auditory nerve. Objective: To analyze the electrically evoked compound action potential, through the neural response telemetry, in children with bilateral cochlear implants. Methods: This is an analytical, prospective, longitudinal, historical cohort study. Six children, aged 1---4 years, with bilateral cochlear implant were assessed at five different intervals during their first year of cochlear implant use. Results: There were significant differences in follow-up time (p = 0.0082) and electrode position (p = 0.0019) in the T-NRT measure. There was a significant difference in the interaction between time of follow-up and electrode position (p = 0.0143) when measuring the N1-P1 wave amplitude between the three electrodes at each time of follow-up. The electrically evoked compound action potential measurement using neural response telemetry in children with bilateral cochlear implants during the first year of followup was effective in demonstrating the synchronized bilateral development of the peripheral auditory pathways in the studied population.

Treatment is based on its etiology, and oral corticosteroids are widely used. Intratympaniccorticosteroids are included as primary or secondary treatment when there is no improvement with the use of oral corticosteroids. Objective: To determine the effectiveness of therapy with intratympanic steroids in sudden deafness. Methods: A systematic review was performed of publications on the topic in the databases of PubMed/MEDLINE, with the keywords: sudden deafness, sudden hearing loss, and corticosteroids. Results: Thirty scientific studies were analyzed. As to the objectives of the study analyzed,76.7% sought to evaluate the use of intratympanic therapy salvage after failure to conventionaltreatment, and intratympanic therapy was used as the primary treatment 23.3% of the studies. Conclusion: Intratympanic corticosteroid therapy is prescribed primarily when there is failureof conventional therapy and when it is limited to use systemic corticosteroids, such as thediabetic patient.

Methods: Analytical, prospective study conducted with 15 participants (30 ears) aged 10-12 years, with bilateral sensorineural hearing loss, attending a Hearing Rehabilitation Center, accompanied by a multidisciplinary team with otolaryngologist, audiologist, psychologist, teacher and social worker. The participants underwent ENT examination and audiological assessment: tympanometry, acoustic reflexes, otoacoustic emissions test and Auditory Evoked response. Results: From the total sample (30 ears), 8 ears (26.7%) presented absent responses in the Auditory Evoked response with the presence of cochlear microphonism. Within the selected eight ears, six (75%) showed presence of otoacoustic emissions test in isolated frequencies and two (25%) ears had otoacoustic emissions test even in the presence of the isolated frequencies. It was found that 26.7% of the ears tested presented results that are compatible with Auditory Neuropathy Spectrum Disorder. The results of this study have identified characteristics related to ANSD in 26.7% of ears tested, 6 participants with age over 10 years old, showing that misdiagnosis in hearing loss patients is still very frequent.
