“…This leads us to reflect on the moment of surgery, which can influence its outcomes on hearing and speech skills with the second CIespecially in children with sequential bilateral CI. 49 The literature agrees that P300 results furnish strong evidence of complex interactions between speech intelligibility, [37][38][39] neural processing, 36,38 verbal working memory, and subjective classifications of hearing effort in CI users. 25,30 Another important factor to consider regarding the use of P300 testing is the advantage in associating objective tests (such as electrophysiological ones) with behavioral tests (such as speech perception ones).…”

Introduction The P300 auditory evoked potential is a long-latency cortical potential evoked with auditory stimulation, which provides information on neural mechanisms underlying the central auditory processing. Objectives To identify and gather scientific evidence regarding the P300 in adult cochlear implant (CI) users. Data Synthesis A total of 87 articles, 20 of which were selected for this study, were identified and exported to the Rayyan search software. Those 20 articles did not propose a homogeneous methodology, which made comparison more difficult. Most articles (60%) in this review compare CI users with typical hearing people, showing prolonged P300 latency in CI users. Among the studies, 35% show that CI users present a smaller P300 amplitude. Another variable is the influence of the kind of stimulus used to elicit P300, which was prolonged in 30% of the studies that used pure tone stimuli, 10% of the studies that used pure tone and speech stimuli, and 60% of the studies that used speech stimuli. Conclusion This review has contributed with evidence that shows the importance of applying a controlled P300 protocol to diagnose and monitor CI users. Regardless of the stimuli used to elicit P300, we noticed a pattern in the increase in latency and decrease in amplitude in CI users. The user's experience with the CI speech processor over time and the speech test results seem to be related to the P300 latency and amplitude measurements.

Objectives: to verify the quality indicators of neonatal hearing screening programs, identify the most prevalent risk factors for hearing loss and analyze access to the Hearing Health Care Network. Methods: cross-sectional study using secondary data. The population are children born in public maternity hospitals from 2015 to 2019. Data collection was carried out in the database of programs and hearing health service. The absolute and relative frequencies of all variables collected and the median, the interquartile range and the Mann-Whitney test were calculated to analyze the access. Results: universality increased during the study period, but was not reached (71.9%; CI95%=70.4-73.3) and the referral rate for auditory diagnosis was within the recommended range (0.9%; CI95%=0.8-0.9). The most prevalent risk factors were congenital infections and heredity. There was an evasion of children to the hearing health service of 85.1% and the type of referral interfered with the age of the child at access. Eight children with hearing loss were diagnosed, in which seven had access to therapeutic interventions. Conclusions: hearing screening was not universal. Access to the Hearing Health Care Network presents high evasion and interventions were offered to children with hearing loss.

“…CI companies are currently working with HA manufacturers to provide communication benefits to individuals with hearing loss. There is abundant scientific evidence regarding the effectiveness of CIs in aural rehabilitation [45][46][47][48][49][50][51][52][53]. In 2009, Laske et al [47] assessed the subjective and objective benefits of CIs in adults.…”
