Tympanostomy and ear tube insertion is the placement of a pressure equalizer tube into the tympanic membrane. This surgical procedure treats middle ear fluid. If left untreated, the fluid can cause otitis media (Acute or Chronic) in addition to hearing loss.
The plastic tube is placed within the tympanic membrane to prevent the quick closure of myringotomy incision. The tube is small and well tolerated by the tympanic membrane, which maintains a ventilatory port for the middle ear space for approximately 1 to 2 years. Prompt insertion of a tympanostomy tube ventilates the middle ear space and prevents further retraction of an eardrum under negative pressure.
