A myringotomy is a surgical procedure in which an incision is created in the eardrum (tympanic membrane) to relieve pressure caused by excessive buildup of fluid, or to drain pus from the middle ear. A tympanostomy tube may be inserted through the eardrum to keep the middle ear aerated for a prolonged time and to prevent ...

It is a special x-ray procedure using dye to look at the womb ( uterus) and fallopian tubes. [2] In this procedure, a radio-opaque material is injected ...
