The procedure, known as tympanostomy, may not be as 【C1】______ as the tonsillectomy was in the 1940s, but it now 【C2】______ as the nation’s leading childhood 【C3】______ and a new study suggests it’s being vastly overused.

Tube placement isn’t a 【C9】______ risky procedure, but it costs $1,000 to $1,500 and sometimes scars the eardrum, causing a partial loss of 【C10】______ Studies show that the benefits are most likely to 【C11】______ the risks if a child’s middle ear has produced sticky fluid 【C12】______ more than four months despite treatment 【C13】______ antibiotics. For less virulent infections, drug treatment is usually a(n) 【C14】______ 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, 【C15】______ doctors had recommended the procedure. Even making "generous assumptions" about the likely 【C16】______ , the researchers found that a quarter of the proposed operations were 【C17】______ , since less invasive alternatives were available, 【C18】______ another third were as likely to harm the recipients as help them.
Parents needn’t 【C19】______ about ear tubes that are already in place. Once 【C20】______ 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.
