“…The consequences of OM in low-and middle-income countries (LMIC), such as hearing impairment (HI), intracranial complications and death, are particularly linked to CSOM [4]. CSOM is a significant cause of preventable HI and a leading cause of HI in school-aged children in Africa [4,11,12]. In Africa, HI seems to persist later in school years even though the CSOM had successfully healed [13].…”

objective To describe the demographics and clinical findings in patients with otorrhoea in Angola. methods A total of 411 patients with otorrhoea presenting in the ear, nose and throat clinic in Luanda and healthcare centres in other Angolan provinces underwent interview and clinical examination. We describe the demographics and clinical characteristics of the patients. results The majority (64%) of patients were children <15 years (age ranged from 1 month to 77 years; median age 10.9 years) while 31% were children <5 years. In 83% of the patients, otorrhoea had lasted >14 days at the time of the examination indicating chronic suppurative otitis media (CSOM), which was confirmed with otoscopy in 72% of patients. Acute otitis media occurred in 16% of patients and was more common in children than in adults (22% vs. 10%; P = 0.007). Median duration of otorrhoea was >12 months. Earache (67%), fever (20%), dizziness (17%), nausea and/or vomiting (6%) were the main symptoms. Adult patients reported noticing hearing impairment (HI) more often than the parents of child patients (72% vs. 50%; P < 0.0001). Reported HI correlated with otorrhoea duration (P < 0.0001), presence of earache, dizziness, and measles or meningitis in history. The level of education in the family did not correlate with symptom duration. conclusions Otorrhoea is mainly due to CSOM and affects patients long-term in Angola. Otorrhoea duration is the strongest predictor of HI. Education on OM and its treatment is needed to prevent HI. keywords Africa, Angola, chronic suppurative otitis media, hearing loss, low-and middle-income country, otorrhoea Sustainable Development Goals (SDGs): SDG 3 (good health and well-being), SDG 4 (quality education), SDG 17 (partnerships for the goals)

“…Firstly, studies have indicated a higher prevalence in younger children (less than 6 years) and older children (more than 12 years). 9,10 Our cohort had a median age of 7.7 years with only a small portion younger than the age of six or older than 12 (Figure 1). Thus, the most commonly affected age groups were under-represented in our study.…”

“…1 Prevalence estimates of CSOM in sub-Saharan Africa range from less than one per cent to more than five per cent of the population. [8][9][10][11][12][13][14][15] However, the number of studies on this is limited and there is great variability in methodology, disease definition and sampling strategy, making precise estimates for the region challenging.…”

Chronic suppurative otitis media in Zimbabwean school children: a cross-sectional study

et al. 2020

Objective Chronic suppurative otitis media is a major cause of disabling childhood hearing loss, especially in low-income countries. Estimates on its prevalence in sub-Saharan Africa range from the lowest to the highest in the world (less than one per cent to more than five per cent). However, the prevalence of chronic suppurative otitis media in Zimbabwe is largely unknown. This study aimed to determine the prevalence of paediatric chronic suppurative otitis media and other middle-ear pathology in rural Zimbabwe. Method A cross-sectional study was performed in primary school children aged 4–13 years from the rural province of Mashonaland East. Participants underwent video otoscopy and tympanometry. Results Out of 451 examined children, two (0.4 per cent) had chronic suppurative otitis media. Acute otitis media was present in one (0.2 per cent), otitis media with effusion was present in five (1.1 per cent) and scarring was present in 69 (15.3 per cent). Conclusion Chronic suppurative otitis media and otitis media sequelae were surprisingly uncommon in this sample of rural primary school children in Zimbabwe. More studies, preferably population-based, are needed to enable more precise estimates of chronic suppurative otitis media prevalence in Zimbabwe.

“…Khairi et al 24 reported that 88.9% of the children with hearing loss had CHL. Hunt et al 25 determined the percentage of unilateral and bilateral CHL, and the results were 24.5% and 12.5% respectively. However, Bess et al 19 found different results: in their study, the rate of SNHL was of 5.4%, and the rate of CHL was of 3.4%.…”

Introduction Hearing is important for the proper development of every child, especially for those younger than 5 years of age, because it helps in the development of language and speech. Emotional and social problems, as well as issues with academic performance, can result from hearing loss even of mild degree. Early diagnosis and management can overcome those negative impacts. Objective To determine the prevalence of mild hearing loss in primary-school children and its association with their school performance. Methods A comparative cross-sectional study was conducted at a regular school. The study included the random selection of 120 apparently normal students (aged 6-9 years) who were considered as having normal hearing by their parents. A total of 20 students were excluded from the study due to the presence of wax in their ears. Finally, the study was conducted with 100 students. All participants were subjected to a basic audiological evaluation, and the Screening Instrument for Targeting Educational Risk (SIFTER) questionnaire was given to their teachers to evaluate their school performance. Results From a total of 100 students, we confirmed that 23 (23%) had mild hearing loss, 17 (17%) had bilateral conductive hearing loss, and 6 (6%) had bilateral sensorineural hearing loss. The students who had low attention and communication performance were significantly associated with mild hearing loss. Conclusion The prevalence of mild hearing loss was of 23% (23 cases). This problem had an effect on the communication and attention in school; and it might affect academic performance later in life. A hearing assessment is highly recommended for every child, especially those who have a low rate of academic performance.
