　　Every year more than half a million American kids have drainage (排泄) tubes surgically implanted in their ears to combat persistent infections. The procedure, know as tympanostomy, may not be as 62___ as the tonsillectomy was in the 1940s, but it now 63___  as the nation's leading childhood 64___  and a new study suggests it's being vastly overused. In 65___  more than 6,000 scheduled ear tube operations, a team of experts 66 ___ by Harvard pediatrician Lawrence Kleinman found that fewer than half were clearly justified. "Each year", the researchers write in the current Journal of the American Medical Association (JAMA), "several hundred thousand children in the United States may be 67___  tympanostomy tubes that offer them no demonstrated 68___  ...and may place them at increased 69 ."
　　Tube placement isn't a 70___ risky procedure, but it costs $1,000 to $1,500 and sometimes scars the eardrum, causing a partial loss of 71___. Studies show that the benefits are most likely to 72___ the risks if a child's middle ear has produced sticky fluid 73___ more than four months despite treatment 74___ antibiotics. For less virulent infections, drug treatment is usually a(n) 75___ , safer alternative (though drugs, too, can be overused). In the new JAMA study, Kleinman's team reviewed the medical charts of 6,429 kids, all under 16, 76___  doctors had recommended the procedure. Even making "generous assumptions" about the likely 77___ , the researchers found that a quarter of the proposed operations were 78___ , since less invasive alternatives were available, 79___  another third were as likely to harm the recipients as help them.
　　Parents needn't 80___  about ear tubes that are already in place. Once 81___  implanted, the tiny devices provide drainage for six months to a year, then come out by reducing health costs by hundreds of millions of dollars every year.
