The procedure, known as tympanostomy, may not be as 67 as the tonsillectomy was in the 1940s, but it now 68 as the nation’s leading childhood 69 and a new study suggests it’s being vastly overused. In 70 more than 6,000 scheduled ear tube operations, a team of experts 71 by Harvard pediatrician Lawrence Kleinman found that fewer than half were clearly justified. \
current Journal of the American Medical Association (JAMA), \thousand children in the United States may be 72 tympanostomy tubes that offer them no demonstrated 73 ...and may place them at increased 74 .\

benefits are most likely to 77 the risks ifa child’s middle ear has produced sticky fluid 78 more than four months despite treatment 79 antibiotics. For less virulent infections, drug treatment is Usually a(n) 80 , safer alternative (though drugs, too, can be overused).
