    In Malaysia 1,307 randomly selected primary school children were screened to find out the prevalence of hearing loss and middle ear disorders. Seventy-six students (5.81%) failed the screening audiometric test. There were 95 students (7.26%) with middle ear disorders. History of ear discharge was absent in 24 out of 57 cases with CSOM (42.11%) (P less than 0.001). Forty-three out of 95 children having middle ear disorders passed the screening audiometric test (P less than 0.01 Fisher exact test). Screening audiometric test fails to detect about 46% of cases with middle ear disorders. Screening audiometric test and otological examination if conducted by the school health medical officers regularly will be able to detect almost all the cases with hearing loss and middle ear disorders.

    OBJECTIVE: To identify the outcomes of hearing screening using different protocols of both Distortion Product Otoacoustic Emissions (DPOAE) and Automated Auditory Brainstem Response (AABR) tests in the same ear of the babies in a neonatal unit population.
    METHODS: A cross-sectional study was carried out on babies who were admitted into a neonatal unit. By using a formula of single proportion and considering 20% drop out, the number of sample required was 114. The subjects were chosen by using a systematic random sampling. The infants selected were subjected to DPOAE followed by AABR tests screening at the same setting before discharge.
    RESULTS: There were 73 newborns (61.6% male and 38.4% female) participated in this study with a total of 146 ears screened. Ototoxic medication was the most common risk factor followed by hyperbilirubinaemia and low birth weight. AABR had higher passing rate (82.9%) as compared to DPOAE (77.4%). The highest passing rate was achieved if the protocol of either passed DPOAE or AABR was used (90.4%). The rate was lower when auditory neuropathy spectrum disorder (ANSD) has been considered (82.9%). Hyperbilirubinaemia, prematurity, craniofacial malformation and ototoxic drugs seem to be the high risk factors for auditory neuropathy.
    CONCLUSION: AABR has a higher passing rate as compared to DPOAE. However, the use of both instruments in the screening process especially in NICU will be useful to determine the infants with ANSD who may need different approach to management. Therefore, a protocol in which newborns are tested with AABR first and then followed by DPOAE on those who fail the AABR is recommended.

    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.

    We surveyed parents of school-aged hearing impaired children to investigate their awareness and knowledge of the special needs of their child, especially in the area of the usage of hearing aids and methods of communication. Questionnaires were distributed to parents of hearing impaired children at 13 special schools for the deaf in Malaysia. Out of 1,267 questionnaires given out, 787 (62.1%) were completed and returned. Results of the survey indicated the majority of parents (68.6%) suspected hearing loss late, that is after their child's first birthday, and there was a significant time lag before the suspicion was confirmed. Over 82.8% of the children were diagnosed only after 1 year of age, with 41.3% being diagnosed after 3 years of age. Hearing aids were fitted late (mean = 5.32 years; SD = 2.66). Hearing aid ownership was influenced by the factors of socio-economic level and ethnic group (p < 0.01) whereas knowledge of use and proper care of the aids was influenced by socio-economic level (p < 0.01). Communication methods were generally inappropriate with 41.3% of the mothers and 48.5% of the fathers reporting ignorance of Bahasa Malaysia Kod Tangan, the sign language that is commonly used by their children. The parents' choice of communication method was not significantly influenced by socio-economic level or ethnic group. The study revealed the present inadequate state of services available for the rehabilitation of children with congenital hearing impairment.

    A cross sectional study to determine the prevalence of hearing loss and hearing impairment was conducted on 286 male subjects from a rural area. The sample was chosen by using a simple random sampling method. Prevalence of symptoms of tinnitus, ear disease, ear drum perforation and infection of external auditory meatus was 19.0 per cent, 6.7 per cent, 3.5 per cent and 0.4 per cent respectively. Air conduction audiometry tests showed the prevalences of hearing impairment of the left, right and both ears (aged 15-30 years) were 5.9%, 8.8% and 0% respectively. The prevalence of hearing loss increased with age. The higher frequencies (> 4KHz) appeared to be more affected than the lower frequencies.

    INTRODUCTION: To correlate the score obtained using a bilingual (Malay and English) 14 points questionnaire in the detection of hearing loss at the University of Malaya, Medical Centre (UMMC), Kuala Lumpur, Malaysia over a 9 month period.

    METHODS: This is a prospective instrument correlation study done on 93 children aged 1-4 years of age with speech and language delay for at least 3 months. Hearing status was confirmed using otoacoustic emissions, pure tone audiometry and brainstem evoked response (BSER). Hearing status was then compared to the 14-point questionnaire final scores and is statistically correlated.

    RESULTS: There were 26 patients, 15 males (58%) and 11(42%) females who were diagnosed to have hearing loss. The average age of presentation was 2.49 and conductive hearing loss accounted for about 74% of cases of hearing loss. The mean questionnaire score obtained through our patients was 3.83±1.987. Discriminant analysis suggests that a questionnaire score of above 4 was indicative that the child was suffering from hearing loss.

    CONCLUSION: Our study suggests that the low-cost bilingual (Malay and English) questionnaire can be used to detect hearing loss in the Malaysian population and could potentially be useful in rural health centres to help detect hearing loss and to determine the urgency of referral to a tertiary health centre.

    Transient-evoked otoacoustic emission (TEOAE) is a well-established screening tool for universal newborn hearing screening. The aims of this study are to measure the effects of background noise on recording of TEOAE and the duration required to complete the test at various noise levels. This study is a prospective study from June 2006 until May 2007. The study population were newborns from postnatal wards who were delivered at term pregnancy. Newborns who were more than 8-h old and passed a hearing screening testing using screening auditory brainstem response (SABRe) were further tested with TEOAE in four different test environments [isolation room in the ward during non-peak hour (E1), isolation room in the ward during peak hour (E2), maternal bedside in the ward during non-peak hour (E3) and maternal bedside in the ward during peak hour (E4)]. This study showed that test environment significantly influenced the time required to complete testing in both ears with F [534.23] = 0.945; P < 0.001 on the right ear and F [636.54] = 0.954; P < 0.001 on the left. Our study revealed that TEOAE testing was efficient in defining the presence of normal hearing in our postnatal wards at maternal bedside during non-peak hour with a specificity of 96.8%. Our study concludes that background noise levels for acceptable and accurate TEOAE recording in newborns should not exceed 65 dB A. In addition, when using TEOAE assessment in noisy environments, the time taken to obtain accurate results will greatly increase.

    The prevalence of auditory neuropathy is not known, although the majority of cases are felt to lie within the population of neonatal intensive care unit graduates. We report three cases of auditory neuropathy, out of 211 children with sensorineural hearing loss, seen at our audiology clinic from April 1, 1999 to December 31, 2003. Two patients did not have a risk factor for hearing impairment. Screening policies based solely on transient evoked otoacoustic emissions testing will not detect auditory neuropathy effectively, and may falsely reassure parents and professionals unaware of this condition.

    OBJECTIVE: This study explored the nature of audiological services for adults with hearing impairment in Malaysia, with an emphasis on whether current services address clients' overall functioning as described by the World Health Organisation's International Classification of Functioning, Disability, and Health (ICF) framework.

    DESIGN: An online survey exploring current practice, skills and confidence of audiologists, and the infrastructure and facilities available in their workplaces, was distributed to audiologists in Malaysia via professional associations and social media.

    STUDY SAMPLE: A total of 111 audiologists, 84.7% female and 15.3% male (range = 23-44 years), participated in the study.

    RESULTS: Although audiologists in Malaysia reported addressing all of the ICF domains, less than 26% of them assessed the patients' speech perception, carried out real-ear measurements, or used outcome measures routinely. The majority of the audiologists reported feeling confident in managing adult patients. However, 83% of the audiologists indicated they wanted to improve their skills related to management of adult patients, particularly in the areas of counselling and auditory training.

    CONCLUSIONS: Inadequate infrastructure, resources and facilities in the workplace may have contributed to the gaps in service provision and influenced the current practice of audiological management for adult patients in Malaysia.
