“…Our results show that the failure rate in the first OAE in VD infants is 1.5 fold higher than CD infants, which is similar to the Farahani ratio [ 34 ] who found that the failure rate was 15.5% in VD infants and 9.5% in CD infants. Likewise, Olusanya et al [ 24 ] stated that VD is associated with more than two-fold risk than a CD.…”

“…On the other hand, Xiao et al [ 35 ] found that 89 (21.0%) CD infants failed the first test out of 423 infants while 74 (7.1%) VD infants out of 1037 failed the test, which means that the rate of failure was 3 fold in CD infants; also Smolkin et al [ 21 ] found that failure rate was 3.2 higher in CD infants compared to VD infants (20.7% vs. 7.1%).Notwithstanding, in our analysis, the difference between CD and VD was not statistically significant with the failure rate of first OAE, which is similar to Güven [ 4 ] and Shahid [ 19 ] findings. On the contrary, previous studies reported that VD is a statically significant risk factor for first OAE failure [ 24 , 34 , 36 ]. Whereas others reported that CD appears to be a risk factor [ 21 , 35 , [37] , [38] , [39] ].…”

Introduction Congenital hearing impairment is one of the principal issues that make distress to families especially those with a family history of hearing problems. Early detection of hearing impairment can make a difference regarding cognitive, attention, learning, speech, and social and emotional development of babies. Otoacoustic test emission is a very common screening test that can be used to pick up early cases and relieve family stress. We tried to evaluate the factors that may disrupt our results regarding the OAE test. Methods A cross-sectional study included infants who were admitted to the nursery unit alone. Infants who were admitted to the NICU unit, infants with craniofacial anomalies, infants with vernix in the external auditory canal, and Infants with Stigmata associated with a syndrome known to include a sensorineural hearing loss were excluded from the study. Both transient evoked otoacoustic emissions (TEOAE) with distortion product otoacoustic emissions (DPOAE) Screening tests were performed by the same professional audiologist experienced in neonatal screening. Results A total of 1413 newborns (733 males and 680 females) were included in the study. Among them, 1368 babies (96.8%) passed the first OAE in both ears, while 45 babies (3.2%) didn't pass the first OAE in one or both ears.Significant correlations between the female gender and family history of congenital hearing loss with failure of the first OAE test results. Moreover, vaginal delivery (VD) infants had a 1.5-fold higher failure rates of first OAE test screening results in comparison to caesarian delivery (CD) infants. Conclusion Our study demonstrated higher failure rates of the first OAE in female infants, vaginal delivery infants, and infants with a family history of hearing impairment. It is recommended to postpone the first phase of hearing screening for those infants until the first scheduled vaccine appointment to achieve higher compliance attendance, and decrease family stress associated with false-negative results of the test.

“…Tabrizi et al have also noted that for higher success rate, the first OAE test after cesarean delivery should be postponed [ 19 ]. In contrast to our finding, Farahani et al have demonstrate that false-positive OAE results in the vaginal delivery group was significantly higher than the cesarean group (15.5% vs. 9.5%) [ 20 ].…”

Perinatal factors influencing the neonatal hearing screening results

Background Previous studies have indicated that the majority of cases with “failed” results related to transient evoked otoacoustic emissions (OAE) test have the normal hearing. The present study aimed to assess the possible relationships between perinatal factors and the false-positive OAE results. Methods A case-control study was carried out in an Iranian Hospital in 2020. Based on the OAE results on the first day of life, newborns were divided into 2 groups; Control group included subjects with “Pass” OAE results. Every neonate with “Fail” OAE result was referred for auditory brainstem response (ABR). Neonates with bilateral fail OAE but normal ABR results (false-positive OAE) were considered as the case group. All recorded data were analyzed to assess the possible correlations between maternal/neonatal factors and the false-positive OAE results. Results One hundred and eighty-one neonates entered the study. Of all included neonates, 87 (48.1%) cases showed bilateral fail OAE and 94 (51.9%) subjects passed the OAE test. Normal ABR results (false-positive OAE) were observed in all cases with bilateral fail OAE. Comparisons of variables affecting the OAE results showed that of all perinatal factors, neonate’s sex (p = 0.046) and cesarean section (p = 0.003) were the only influencing factors that increased the risk of false-positive OAE results. Conclusion Based on the results, the cesarean section delivery and neonate’s male sex increased the risk of false-positive results related to OAE test. Implementing other screening tests such as ABR or Automated ABR as the initial screening test could be suggested for such cases.

“…They reported that the first screening with high false-positive results caused anxiety in the family and it would be important to perform the test at the 48 th hour postoperatively to reduce the cost [2]. On the other hand, Farahani et al showed that false positivity rates in hearing tests may be high in the early period owing to low tympanic membrane motility and fluid accumulation in the middle ear in the case of normal delivery [15]. In our study, cesarean deliveries without maternal-fetal risk factors were selected to exclude changes in the study group possibly due to the physical effects of the delivery method.…”

Background Hearing is essential for the healthy development of an infant as language is one of the main stimulants of intellectual capacity. We investigate the effect of anesthesia type during delivery on neonatal otoacoustic emission (OAE) hearing test results. Methods This retrospective cross-sectional study includes 1,493 healthy, full-term (39/0–40/6 gestational weeks) newborns of healthy women and who were delivered by cesarean section. Newborns were divided into 2 groups based on their anesthesia type during delivery: 1) general anesthesia group (n=160), and 2) spinal anesthesia group (n=1333). Maternal age, anesthesia type, birth weight, gestational age at birth, neonatal gender, 1st–5th minute APGAR scores, and OAE results were compared between the groups. Results 1287 (86.2%) newborns were reported to have passed the first step of OAE; 206 (13.8%) newborns were reported to have failed the first step and passed the second test. In the general anesthesia group, 133 (83.1%) of the newborns passed the first OAE test and 27 (16.9%) newborns had false-positive results. In the spinal anesthesia group, 1,154 (86.6%) of the newborns passed the first OAE test and 179 (13.4%) newborns had false-positive results. The difference between the 2 groups by false-positive values was found to be statistically significant (p<0.001). Conclusions Type of delivery anesthesia may have an effect on the false-positive rates of OAE test results.
