“…Another study compared TEOAEs and DPOAEs and concluded that TEOAEs testing is easier to carry out and it is more trustworthy when compared to the DPOAEs test. According to this study, the specificity for TEOAEs was found to be 92%, which is fairly consistent with our study findings of 88.88% (96 passed) for OAE [23]. One more study determined that DPOEs followed by confirmation by BERA is a very beneficial tool for the initial identification of congenital hearing loss in neonates, which also validates our study findings as it was consistent too, and matched with other studies to some extent [24].…”

Objective In this study, we aimed to assess the incidence of hearing loss in the pediatric population through otoacoustic emission (OAE) and brainstem evoked response audiometry (BERA) and to analyze the possible etiological factors responsible for it. Material and methods A retrospective observational study was conducted in the Otolaryngology (ENT) and Gynecology and Obstetrics Departments at the Jinnah Postgraduate Medical Centre and National Institute of Child Health in Karachi, Pakistan between July 2019 and October 2019. The convenient sampling technique was used to select the patients. The final sample size consisting of newborns and children was 108. Initially, screening procedures were undertaken for newborns to detect permanent or fluctuating, bilateral or unilateral, and sensory or conductive hearing loss, averaging 30-40 dB or more in the frequency region, which indicated potential issues related to speech recognition (approximately 500-4,000 Hz). The screening of newborns involved the use of non-invasive, objective physiologic measures that included OAEs and/or auditory brainstem response (ABR). The children with hearing impairment then underwent BERA; thereafter, further investigations were performed to confirm the defects found on BERA testing. Results Of the 108 cases, 96 had normal hearing on OAE screening, and 12 were found to have hearing loss on the OAE test. Further testing was carried out on BERA for 12 cases that had been detected to have hearing loss on OAE, and BERA showed normal hearing for five cases whereas seven were found to have hearing loss. Of the seven patients with hearing loss on the BERA test, five were diagnosed with cochlear deafness, and two had retrocochlear deafness. Conclusion Our present study concludes that in order to avoid any hearing problems in infants, OAE hearing screening and diagnostic BERA screening programs should be carried out in all the hospitals of Pakistan to assess newborn hearing at an early age.

“…Another study also found a statistically significant association between sex and hearing loss (16) . Sensorineural hearing loss, which is more common in males, is caused by a shorter cochlear length in females, so that acoustic stimulation reaches the outer hair cells more quickly thus the exposure to the cochlea in males is greater than in females (17) .…”

Background: Neonatal Asphyxia is one of the risk factors for hearing loss in children. Neonatal Asphyxia causes cochlear damage due to lack of oxygenation and tissue perfusion which can lead to cell death. Objective: Determining the risk of Neonatal Asphyxia for the occurrence of sensorineural hearing loss in children. Methods: A case control study was done between July to September 2020. Children with sensorineural hearing loss are on study group and the control group is children with normal hearing. Participants were measured for previous labor history based on medical records that confirmed asphyxia. Participants were also examined for DPOAE and ABR / BERA. The measurement results were analyzed using the Chi-Square test, which was significant if p <0.05. Results: Most participants aged 2-3 years experienced hearing loss (65.96%) and normal (68.08%; p = 0.835). Participants of sensorineural hearing loss with Neonatal Asphyxia (57.4%) were more than non-Neonatal Asphyxia (42.6%; OR = 1.82; 95% CI 0.81 -4.13; p = 0.149). Conclusion: Neonatal Asphyxia increases the risk of sensorineural hearing loss by 1.82 times compared to children without Neonatal Asphyxia.

“…Hair cell function can be tested using transient-evoked otoacoustic emissions (TEOAE) or DPOAE. TEOAE generally produces a linear reflection influenced by the status of the entire cochlea, whereas DPOAE allows for testing of more specific regions within the cochlea and results in reflection characterized by nonlinear distortion (Tzanakakis et al 2016). However, both tests have shown similar sensitivity and specificity with both methods utilized for hearing screening (Tzanakakis et al 2016).…”
