The objective of this prospective study was to report on the prevalence of hearing impairment in the neonatal unit population. From 15 February 2000 to 15 March 2000 and from 15 February 2001 to 15 May 2001, 401 neonates were screened using transient evoked otoacoustic emissions (TEOAE) followed by second-stage screening of those infants who failed the initial test. Eight (2 per cent) infants failed one ear and 23 (5.74 per cent) infants failed both ears, adding up to 7.74 per cent planned for second-stage screening. Five out of 22 infants who came for the follow up failed the screening, resulting in a prevalence of hearing impairment of 1 per cent (95 per cent confidence interval [95% CI]: 0.0–2.0). Craniofacial malformations, very low birth weight, ototoxic medication, stigmata/syndromes associated with hearing loss and hyperbilirubinaemia at the level of exchange tranfusion were identified to be independent significant risk factors for hearing impairment, while poor Apgar scores and mechanical ventilation of more than five days were not. In conclusion, hearing screening in high-risk neonates revealed a total of 1 per cent with hearing loss. The changes in the risk profile indicate improved perinatal handling in a neonatal population at risk for hearing disorders.

Newborn Hearing

Although the importance of identifying significant hearing loss at an early age has long been recognized, it is generally acknowledged that newborn hearing screening programs in the United States have not been very successful. The problem has been that available techniques were impractical, too expensive, or invalid. This article summarizes the data regarding the use of transient evoked otoacoustic emissions (TEOAE) in a universal newborn hearing screening program and describes various facets of program implementation. It is concluded that available data provide clear evidence that TEOAE can be used to significantly reduce the average age of identification for hearing loss in the U.S.

The Relationship

The objectives of the study were to demonstrate hearing status in newborns at first screening by Transient Evoked Otoacoustic Emissions and to find out the relationship between abnormal hearing screening and known risk factors. This study was conducted in the department of neonatology of Bangabandhu Sheikh Mujib Medical University in collaboration with department of otolaryngology and department of obstetrics and gynaecology. This prospective observational study included a cohort of 168 neonates from Neonatal Intensive Care Unit and neonatal Nursery (Minimal care unit). All were screened for hearing impairment using Transient Evoked Otoacoustic Emissions in out-patient department of otolaryngology by a trained audiologist before discharge from hospital. Risk factors analysed were according to the criteria of American Academy of Pediatrics. Of the total neonates screened, Refer rate was 32.7% irrespective of presence or absence of risk factors. Small for gestational age, in-utero infections, ototoxic medications, birth weight <1500, sepsis/meningitis, hyperbilirubinemia were found to be significant risk factors (p<0.0001). It can be recommended that hearing screening should be universally done for all newborns. DOI: http://dx.doi.org/10.3329/bmrcb.v40i1.20319 Bangladesh Med Res Counc Bull 2014; 40: 1-5

Congenital heart disease (CHD) is 1/3 of all congenital malformations and one of the main causes of infant mortality. Hearing loss may be part of syndromes associated with CHD, or the hearing pathology can be a consequence of the various stages of rehabilitation of underlying pathology. Currently, there isn’t any data on the systematic study of hearing impairment in children with congenital cardiac pathologies. Three hundred and six patients aged 2 days to 8.5 months were examined: 96 patients were included in the main group with CHD, and 300 children without CHD made up a comparison group. All children underwent newborn hearing screening. Infants with suspected hearing pathology were tested with a comprehensive audiological examination. In the CHD group hearing impairment was detected in 29% of children, including sensorineural hearing loss (SNHL) in 12%. And in the comparison group, 3.6% of infants had a hearing loss, SNHL was defined in 1%. Analysis of the data revealed the most significant risk factors for hearing impairments in children with CHD and it had showed the difference in the structure of the risk factors between the both groups. In the study group was registered a case of auditory neuropathy spectrum disorders. This case illustrated the importance of conducting hearing screening by means of click-evoked auditory brainstem responses and not only of registration of otoacoustic emissions. One child with CHD was found to have delayed SNHL, which requires long-term monitoring of hearing in children with cardiopathology.

Universal Hearing Screening

AbstractA retrospective review of 168 consecutive children with congenital or early-onset bilateral hearing impairment (>25 dB, 0.5–4 kHz, in the better hearing ear) was conducted. Only 39 per cent of the hearingimpaired children were diagnosed within the first two years of life. The age at diagnosis was related to the severity of hearing loss with profound (>95 dB) hearing losses being detected earlier than the other degrees. However, 37 per cent of children with severe to profound (>70 dB) hearing loss were still not diagnosed until after two years of age. Children with severe to profound hearing loss and with known risk factors were diagnosed earlier than children with the same hearing status but with no known risk factors. It was concluded that the behavioural hearing screening tests used in our well-baby clinics are insufficient and, therefore, more reliable methods, preferably evoked otoacoustic emissions, should be used for universal hearing screening of infants and young children in spite of the great cost.

Background: Mastoidectomy is the mainstay of COM treatment . Usage of the micro motor drill has an effect on the contralateral ear due to the noise induced by the drill and the sound-conducting characteristic of the intact skull. Aims And Objectives: 1. To identify the drill induced hearing loss in the contralateral ear, by transient evoked otoacoustic emissions following mastoidectomy. 2. To identify the relation between the type of burr tip used and the amount of hearing loss. Methodology: This study consisted of 63 patients that underwent mastoidectomy. A pre-operative PTA and TEOAE was done. PTA was repeated on POD-1 and POD-7. TEOAE was done on POD-1,3 and 7. Intraoperatively, the type of burr tip used and the individual drilling time for each type of drill bit was recorded. Results: 37 patients developed transient SNHL by POD-3. All patients recovered by POD-30. Higher frequencies of 3000 Hz and 4000 Hz were commonly affected. No change was detected on PTA. Conclusion: The drill is not only a source of noise but is also a strong vibration generator. These strong oscillations are transmitted into the cochlea. Thus surgeons should select appropriate burrs and drills to minimize the temporal bone vibrations.

Introduction  The present study was devised to estimate the prevalence of neonatal hearing loss and document the importance of using DPOAE as a screening tool for identifying hearing loss in newborns. Materials and Methods This hospital based descriptive study was conducted from August 2018 to August 2019. A total of 928 newborn babies were included in the study. These newborn babies were subjected to hearing screening by distortion product otoacoustic emissions (DPOAE) at 24-72 hrs after birth. For pass cases, no further testing was done. For refer cases, repeat testing with DPOAE was done within 15-30 days. Newborns with refer result on repeat DPOAE testing were subjected to Brainstem evoked response audiometry (BERA) within 3 months to confirm hearing loss. Results Nine hundred and twenty eight newborn babies were screened by DPOAE. 851 newborns passed the first DPOAE hearing screening and 77 newborns gave refer result. 21 newborns were lost to follow-up. 56 newborns underwent repeat DPOAE testing and 5 newborns were referred for BERA. Amongst the 5 newborns who underwent BERA testing, one newborn was diagnosed with bilateral profound hearing loss. Hence, the prevalence of hearing loss of 1.08 per thousand newborn babies was estimated in this study. Conclusion Hearing screening of newborns using DPOAE followed by BERA in refer cases to confirm hearing loss is useful for early detection followed by timely intervention and rehabilitation.

Reduction of hearing is the most common sensory impairment among newborns with an incidence of 1-3 per 1000 births. Introduction of an Auditory Newborn screening program allows early identification of hearing impairment. Mainly, congenital hearing loss in early childhood is a result of genetic changes. Due to high frequency of GJB2 pathogenic variants, its molecular characterization among sensorineural hearing reduction cases is already conducted as a routine analysis in many countries. The aim of this study is to show our initial results in the effort to determine whether genetic screening along with the standard hearing screening in newborns is justified. Otoacoustic emission (OAE) method was conducted in 223 newborns at risk of hearing impairment. Among them, 7 did not pass the test in both ears while 9 exhibited one-sided hearing loss. In all 7 children with indication of profound bilateral deafness, the diagnosis was confirmed using auditory brainstem response. Genetic screening of GJB2 gene was performed in 6 of them. Genetic analysis of GJB2 revealed homozygous state of the most common pathogenic variant 35delG in 3 (50%) of the analyzed infants. In the remaining 3 no pathogenic variant was determined. The results indicate that performing auditory OAE together with genetic screening is justified. In newborns who have not passed the hearing screening test and have profound hearing loss, without other syndrome traits, screening for mutations of GJB2 gene should be conducted. Genetic screening enables establishment of early definite diagnosis for deafness and helps in conducting adequate therapy providing timely rehabilitation and social inclusion of deaf child.

Introduction: Hearing loss is one of the most common congenital disorders. The prevalence of this disorder in different communities has been reported between 3.5 to 9 percent, which can have adverse effects on language learning, communication, and education of children. Also, early diagnosis of this disorder in newborns is not possible without the use of hearing screening. Therefore, the aim of this study was to evaluate the effectiveness of newborn hearing screening programs in Zahedan. Method: In this cross-sectional observational study, all babies born in the maternity hospitals of Zahedan city (maternity hospitals of Nabi Akram, Imam Ali, and Social Security hospitals) in 2020, were examined. In order to conduct the study, TEOAE was initially performed for all neonates. Then, based on the results obtained in the ODA test and in case of unsatisfactory response, cases were referred for re-evaluation. Infants who were rejected again in the second stage were immediately subjected to the AABR test and if they failed in this test, they were also subjected to a diagnostic ABR test. Results: Based on our results, 7700 infants were first evaluated with the OAE test. Of these, 580 (8%) had no OAE response. Out of 580 infants rejected in the first stage, 76 infants were also rejected in the second stage; Among them, 8 infants were re-diagnosed with hearing impairments. Finally, out of 3 infants who were diagnosed with hearing loss, 1 (33%) had conductive hearing loss and 2 (67%) had sensorineural hearing loss. Conclusion: Based on the findings of the present study, the implementation of a comprehensive neonatal hearing screening program is necessary for the timely and early diagnosis and treatment of hearing loss. Also, screening can improve the health of children and their personal, social, and educational development in the future. Keywords: Hearing screening, hearing loss, newborns, OAE, AABR
