DOI: 10.1177/000992289403300103 Effect of Cotton-Tipped Swab Use on Earwax OcclusionDepartment of Pediatric and Adolescent Medicine
Department of Pediatric and Adolescent Medicine
Department of Biostatistics and Epidemiology The Cleveland Clinic Foundation Cleveland, Ohio We studied parents' and patients' approach to earwax (cerumen) removal, patients' level of cerumen occlusion, and the association between the use of cotton-tipped swabs (CTS) and cerumen occlusion. Six hundred fifty-one consecutive patients from the general pediatric practice of the Cleveland Clinic aged 2 weeks to 20 years (57% males) answered a questionnaire with their parents' help. Of the 651, 401 (62%) had used CTS during the 2 months before the study. Examiners unaware of the questionnaire results found that 46 (7%) of both right and left ear canals were at least 75% occluded by cerumen. Cerumen occlusion of at least 75% was associated with CTS use on the left side (P= .02), but not on the right side (P= .27). We conclude that cotton-tipped swab use may be associated with cerumen accumulation.
