Use and abuse of cotton buds (2024)

Abstract

Ear injuries caused by cotton buds are commonly seen in ear, nose and throat (ENT) practice. We asked 1000 patients attending an ENT referral clinic whether they used cotton buds to clean the ear canal. Of the 325 who responded, 171 said they did. The frequency of use was no higher in those with ear complaints than in those with nose and other complaints. 15–20% of respondents disagreed with the statements that cotton buds can cause infections, wax impaction or perforations. On the evidence of this survey, manufacturers' warnings need to be fortified.

INTRODUCTION

Cotton buds were developed in 1923 by Leo Gerstenzang.1 After observing his wife using wads of cotton on toothpicks to clean his baby's ears, he developed a cotton-tipped swab that he considered safer. The product was initially called Q-tips Baby Gays (Q for quality) and Q-tips survive to this day. The first instances of medical concern over the use of cotton buds were in 1972 with reports of tympanic membrane perforation, otitis externa2 and cerumen impaction.3 Manufacturers then advised against use of cotton buds in the external auditory canal. Nonetheless, cotton-bud-related injuries are a common reason for attendances at ear, nose and throat (ENT) referral clinics.4 We asked patients attending an ENT clinic about the practice.

METHODS

All patients attending an ENT urgent referral clinic in two months were invited to complete an anonymous questionnaire (available from authors). About 500 patients attended per month and 325 responded, with some questions answered according to a 5-point Likert scale—strongly disagree, disagree, not sure/neutral, agree, strongly agree. We also wrote to nine manufacturers and retailers of cotton buds inquiring about the wording of any warnings on packaging and how long such a warning had been present. For the two who did not reply, we made our own purchases.

RESULTS

325 patients, 173 male, answered the questionnaire, average age 41 years (range 9–92). In 232 patients the symptoms were ear-related, in 40 nasal, in 31 throat and in 22 other. 171 (53%) respondents said they used cotton buds to clean their ears, and the frequency in those with ear symptoms was about the same in those with other complaints. Table 1 lists reasons for cotton bud use. Likert scale responses to a series of statements are summarized in Table 2. Concerning the potential complications of cotton bud use, the numbers expressing ignorance ('strongly disagree' or 'disagree') were: 'can cause infections of the ear' 64, 'can cause a perforation of the eardrum' 51, 'can push ear wax deeper into the ear' 47. The warnings of nine companies are shown in Table 3.

DISCUSSION

Ear wax is a mixture of ceruminous gland secretions, squames of epithelium, dust and other foreign debris.5 It is expelled by epithelial migration from the tympanic membrane, aided by movements of the temporomandibular joint.6 This process renders the ear 'self-cleaning'. Unwise efforts with a cotton bud can produce wax plug impaction, with resultant discomfort, deafness and vertigo,7 injury to the external auditory canal or perforation of the tympanic membrane.2,8 Otitis externa can likewise be caused by overzealous use of cotton buds.9

The survey reported here is best regarded as qualitative. The response rate was too low for quantitative validity, and we cannot tell whether the behaviour of the ENT patients typified that of the wider population—or whether, indeed, some of them had cotton-bud-induced disorders. What the survey does indicate is that warnings against use in the ear canal are quite widely discounted or ignored. Most cotton bud users, when asked why they did it, merely said 'it seems like a good idea' or family and friends use them. Fortunately, only a small number had been advised to do so by medical professionals. We have to admit that a large number of people use cotton buds without coming to harm and the actual risk remains to be elucidated. Cotton bud manufacturers are explicit in their warnings against use in the ear, but on the evidence of this survey these warnings need to be stronger.
