“The two biggest misconceptions I hear as an otolaryngologist are that the ear canals need to be cleaned in the home setting, and that cotton tip applicators should be used to clean them—both of those are incorrect,” Jatana added. “The ear canals are usually self-cleaning.” The study, published in The Journal of Pediatrics in 2017, compiled 20 years worth of data from 1990 to 2010 and found that more than 263,000 children under the age of 18 had been admitted to U.S. hospitals for ear injuries as a result of using cotton swabs. Of those hundreds of thousands of injuries, ear cleaning was the most frequently documented cause (73 percent of recorded injuries). According to Jatana and his team of researchers, the first time medical concerns were brought up about cotton swabs was in 1972—nearly 50 years after they were first created. This study from the ’70s indicated that there were reports of tympanic membrane perforation (TMP), otitis externa, and cerumen impaction after using cotton swabs. And this created a spur of health officials advising against the use of cotton swabs in the ear canal and manufactures creating warning labels on their products.ae0fcc31ae342fd3a1346ebb1f342fcb Despite this early study and subsequent warnings, people continue to regularly use cotton swabs to clean their ears. A study from 2011 found that 68 percent of people still report using cotton swabs in their ear, with 96 percent saying they use them to clean their ear of earwax.
