参考答案：C
解析：The tympanostomy tubes, made of a polyurethane material that does not change in structure or composition while in the ear, usually remain in place for about 6 months then are spontaneously ejected from the ear. Parents should be told about the tubes appearance so they can observe them if they fall out.
