Effectiveness of Water as a Softening Agent for Impacted Cerumen in Children: A Randomized Trial

This study investigates the effectiveness of water as a softening agent for removing impacted cerumen in children. Conducted with 42 patients, it compares an intervention group using water drops for 15 minutes against a control group using olive oil applied nightly for three days. Although both groups showed improvements, the difference in earwax clearance was not statistically significant (p=0.18). The findings suggest that water is an accessible and cost-effective alternative for managing impacted cerumen in children, offering safety and practicality in general practice.

  2. Clinical SITUATION • Increasing number of children in the community with impacted cerumen • Finding cost-effective means of addressing this problem

  3. ResearchQuestion Among children with impacted cerumen, is the application of water as a softening agent effective in clearing the ear canal (using a randomized control trial)?

  4. A quasi-randomised controlled trialof water as a quick softening agent of persistent earwax in general practice A Journal Article on Therapeutics

  5. METHOD • Population: • Patients with persistent earwax (more than 75% obstruction after 5 attempts of syringing) • Intervention group: 22 patients • Control group: 20 patients

  6. METHOD • Water (room temp) dropped at affected ear until ear is full and canal covered with a wad of cotton • left for 15 minutes in the waiting area of an actual patient encounter • Irrigation with 100cc syringe • Olive oil dropped on affected ear until ear is full and covered with a wad of cotton • Done every night for 3 days before patient encounter • Irrigation with 100cc syringe Intervention -water Control -mineral oil

  7. Validity • Was it Randomized? Was randomization concealed? • The patients were randomised into an intervention group (n = 22, year of birth was even) and control group (n = 20, year of birth was odd). • Intervention Group – drops of water for 15mins. • Control Group – oil at night for 3 days

  8. Results of the Study • Intervention group: 3.0 ((95% CI = 2.4 to 3.6) • Control group: 2.4 (95% CI = 1.7 to 3.1). • The difference between these means (0.6; 95% CI = -0.3 to 1.5) • P value: 0.18 (not statistically significant)

  9. Applicability • Water can be an alternative softener for impacted cerumen. • Water is very accessible and not costly(can be more practical than spending for oil) • Though syryinging is not the most preferable method by otolaryngologist, the practice can be considered generally safe to apply
