“…Both ears were tested for hearing impairment. The test was first conducted for the right ear at 1000, then 2000, 4000, 8000 hertz, then 500 Hz and 250 Hz in that order [17] [18]. The test started at 40 dB HL, if audible then was reduced in 10 dB steps till no response occurred, then it was increased in 5dB steps till a response occurred and the results were plotted [17] [18].…”

“…The left ear was then tested and the same process for air conduction was repeated. For bone conduction (BC) test, the bone vibrator was placed on the mastoid bone of the test ear delivering different tones at frequencies of 500, 1000, 2000, 4000 hertz [17] [18].…”

“…Hearing loss was classified as sensorineural (SNHL) if the air bone gap was less than 10 dB and conductive if the air bone gap was greater than 10dB. Mixed hearing loss is when the air bone gap was greater than 10dB and bone conduction was impaired [17].…”

“…The hearing threshold was classified based on WHO (2014) as follows; no impairment (0 -25 dB), mild hearing loss (26 -40 dB), moderate hearing loss (41 -60 dB), severe hearing loss (61 -80 dB) and profound hearing loss (>81 dB) [17]. The hearing-threshold of the pupils was then compared based on their social class (low social class and high social class).…”

“…Normal hearing plays a vital role in good psycho-social development of children [4]. Otologic diseases causing hearing impairment during early childhood might have negative effect on the child, which may cause delayed cognitive skills, speech and language development often resulting in poor performance in school compared to those with normal hearing threshold [3] [4] [5] [6]. However, despite the high prevalence rates of otologic diseases among paediatric age group and its possible consequences on psycho-social development of these children, there are very few studies carried out that compared ear diseases of children from high versus low socioeconomic classes; and most, if not all, of the studies were from Asia, and none of these available studies appear to have been carried out from the Northern part of the country [7]- [12].…”

Background: Preventable otologic conditions have been found to be important health issues among paediatric age group. Poor socioeconomic status and inappropriate management services in developing countries lead to various complications despite the fact that most of these diseases are self-limiting. The aim of this study was to determine the prevalence and pattern of ear diseases in school children of high and low socioeconomic status in Yola, Nigeria. Methods: This study was conducted in March 2017 in two primary schools (private and public) in Yola among 6 -8 years old pupils. Approval for the study was obtained from Federal Medical Centre, Yola and consent was obtained from the parents/guardians and the school authorities. Using a health questionnaire, a brief ENT history was obtained from children in years 1 and 2 of each school. Otoscopic examination, audiometry and tympanometry were then carried out. Data collected was analysed using SPSS version 20. Results: One hundred and three children were studied. The age range was 6 -8 with mean age of 6.8 ± 0.9 and 53 (51.5%) boys. Fifty-two (50.5%) were from public school (low socio-economic class) and 51 (49.5%) from private (high social class). Wax was the most common ear condition encountered affecting 37 (35.9%) children, and the number was similar in both groups. Otitis media with effusion (OME) was encountered in seven children evenly split between the two groups showing a point incidence of 6.8%. There was hearing loss in 13 (12.6%) children, and this was also similar in the two groups. Conclusion: Wax impaction was the commonest otologic disease encountered. Our study also showed a point incidence of 6.8% for OME, but there was no statistical difference between the two groups, and neither was there How to cite this paper:

Background: Prisoners, due to confinement are isolated from contact with the society and access to many of the facilities, including medical care. This study aimed to evaluate the hearing threshold of inmates of Kaduna convict prison. Method:It was a cross-sectional study of prison inmates at the Kaduna convict prison between April 2017 and February 2019. Ethical approvals were obtained from relevant bodies and all consented inmates aged 18 – 55years in the Kaduna convict prison were enrolled. Equal number of control matched for age and gender were enrolled from the communities in Kaduna North Local Government Area. Data were collated using a structured questionnaire. A diagnostic Pure Tone Audiometry was performed to assess their hearing threshold. Statistical Package for Social Sciences (SPSS) version 20.0 was used for analysis. Results:Four hundred and thirty inmates and equal number of control group were enrolled. The mean age for the inmates and controls were 30.2±7.5 and 30.4±8.02years respectively. There were 383 males and 47 females in both groups. Among the 860 ears of the inmates, 238(27.7%) ears had hearing loss while in the control group, 95/ (11.1%) ears had impaired hearing. Conductive hearingloss was the commonest among the inmates 111(46.6%) while sensorineural was commoner among the controls 57(60.0%). The mean pure tone average among the inmates was 25.6±11.3dBHL and 26.1±11.2dBHL on the right and left ears respectively while in the control group, it was 18.4±7.8dBHL on the right and 17.9±7.9dBHL on the left. Conclusion:This study revealed that hearing loss was more prevalent among prison inmates than the general population. In majority of the inmates, the hearing loss was mild, conductive and mostly affecting all the frequencies Keywords: Hearing threshold, Kaduna, Nigeria, Prison inmates

Background: Hearing loss being a hidden disability attracts less sympathy from the public as well as governmental and non governmental organizations.Objective: The Objective of the study was to determine the prevalence and pattern of hearing loss among patients seen at the out patient unit of Ear, Nose and Throat clinic of the Yobe State University Teaching Hospital, Damaturu, Yobe State, Nigeria. Patients and Methods: This was a retrospective study of all registered patients with hearing impairment seen at the department of Ear, Nose and Throat, Head and Neck Surgery of the Yobe State University Teaching Hospital, Damaturu from 1st January, 2018 to 31st December, 2018. Case files were retrieved and reviewed. Data was extracted and entered into a Proforma. Extracted data include socio-demographic information, mode of presentation, examination findings, diagnosis, investigations done, treatment offered and outcome. The generated data was analyzed using SPSS version 20. Results: Seventy four, out of the total 1268 patients seen at the department of Ear, Nose and Throat clinic within the period under review, had hearing loss making a hospital prevalence of hearing loss of 5.8%. Median age of the participants was 20 years (range 2months-80years). Middle ear infections accounted for majority of the aetiologic factors and most patients presented with bilateral, moderate mixed hearing loss. Most patients had ear dressing to achieve dryness while 6 had tympano-mastoidectomy. Conclusions: The prevalence of hearing loss is low, with most patients presenting with ear discharge. The pattern found in the majority of the patients is bilateral moderate mixed hearing loss
