Purpose
Cerumen impaction is a public problem of great concern due to associated hearing impairment. Despite cerumen impaction being one of the commonest causes of hearing loss among primary school children, there is no any published study to date from northern Tanzania focused on this topic. This study aimed to address this gap.
Methods
A cross-sectional study design was used where 307 primary school pupils were recruited using a multistage cluster sampling technique and it was conducted from January to July 2023. Data was collected using Swahili translated semi-structured questionnaires.
Results
The prevalence of cerumen impaction was 10.7% with the right ear being mostly affected (57.6%). A statistically significant association was found between prevalence of cerumen impaction and mother’s education level though no association was found between sex, residence, father’s education level and mother’s occupation status. Predisposing factors like history or presence of ear infection, habit of cleaning ears and using hearing aids or earphones showed a statistically significant association The commonest clinical presentation was otalgia (36.4%) and washing ears with water (71.5%) was the commonly applied method of cleaning the ears apart from hospital based interventions. The commonest method of wax removal for those who visited health facilities was ear syringing (42.9%).
Conclusion
Lesser prevalence of cerumen impaction was found in this study though majority had previous history of impacted wax. Cotton bud was the commonest predisposing factor for cerumen impaction. The commonest clinical presentation among those with impacted cerumen was otalgia though some pupils reported asymptomatic cerumen impaction.
