“…A study comparing TOAE and tympanometry results with infants with no hearing loss risk indicators showed a greater proportion of tympanometric alteration in the group of infants with absence of TOAE, 21 corroborating the findings of our study. Otitis media with effusion is often asymptomatic and can go unnoticed owing to its symptoms being less evident than those of acute otitis media.…”

“…20 Tympanometry consists of checking the mobility of the tympanic-ossicular system through the variation introduced into the external auditory meatus, being effective in the early identification of middle ear disorders. 20,21 Recurrent otitis and diseases that affect the middle ear are very common in children and infants and this is why tympanometry was used in the hearing screenig.…”

Objective: to describe the results of hearing screening performed in children with Congenital Zika Virus Syndrome (CZS) in Fortaleza, Ceará, Brazil. Methods: this was a descriptive cross-sectional study involving children with CZS receiving health care in Fortaleza, 2016; the hearing screening tests performed were immittance audiometry, transient otoacoustic emissions (TOAE), acoustic reflexes, and cochleopalpebral reflex (CPR). Results: The study included 45 children with an average age of 10 months. 44 of them underwent tympanometric screening, with 16 of these having the right ear within the normal range and 22 having the left ear within the normal range. Among the 43 children evaluated by TOAE, 30 "passed" in both ears, nine "refered" in both ears and four "refered" just in ear; 13/43 "refered" and needed to repeat screening. 43 children evaluated by CPR, 37 showed responses. Conclusion: most of the children evaluated had completed cochlear function and middle ear results refer in compatible with their age range.

“…In this study, for newborns in Group I, the mean ASRT obtained with the 226 Hz probe was lower (Table 1) in all frequencies in comparison to that found by other studies (14,24) . With the 1,000 Hz probe, the average was 74.2 dB for the 1,000 Hz frequency and 62.9 dB for 2,000 Hz (Table 1).…”

“…43 There was no significant difference between gender and frequency. A study (24) observed newborns and the association between Transient-Evoked Otoacoustic Emission (TEOAE) and changes in acoustic immittance with a 226 Hz probe. For that, the authors assessed 20 newborns with absent TEOAEs (experimental group) and 101 with TEOAEs (study group).…”

PURPOSE: To analyze the occurrence of acoustic reflex and its threshold on newborns using the 226 and 1,000 Hz probes. METHODS: Thirty-six newborns with "PASS" results in newborn hearing screening and tympanogram with one or two peaks for both probe tones were included. Group I comprised 20 full-term newborns without risk indicator for hearing loss, and Group II comprised 16 newborns with at least one risk indicator. The study about ipsilateral acoustic reflex thresholds was conducted in 500, 1,000, 2,000, and 4,000 Hz. RESULTS: The groups presented the acoustic reflex thresholds between 50 and 100 dB for both probe tones. In the comparison between the probes, there were differences in all frequencies evaluated in Group I, with the lowest threshold mean for the 1,000 Hz probe. In Group II, differences were detected at 2,000 Hz. The mean acoustic reflex thresholds were similar in both groups for the 226 Hz probe. There was a difference for the 1,000 Hz probe in all tested frequencies. The percentage of response was higher in both groups for the 1,000 Hz probe. The kappa test showed extremely poor agreement in the comparison of results between both probes. CONCLUSION: The occurrence of acoustic reflex was higher in newborns and its thresholds were lower with the 1,000 Hz probe both for healthy newborns and for newborns at risk.

“…3,4 Consequently, abnormal ME status is an important cause of absent or diminished OAEs in newborns undergoing hearing screening. Conversely, newborns that fail the OAE screening tests are more likely to have abnormal acoustic immittance test outcomes, 5 with 50% of newborn ears failing OAE tests reportedly having ME effusion or dysfunction. 6 Approximately four per 1,000 newborns had ME pathology with or without conductive hearing loss in one study.…”
