Tympanocentesis is the drainage of fluid from the middle ear, usually caused by otitis media, by using a small-gauge needle to puncture the tympanic membrane (eardrum).
Main indication for tympanocentesis is failed treatment with antibiotics.
It is sometimes referred to as a "tap" and, when conducted twice as part of a clinical trial of medication, a "double tap."
