Tympanocentesis
Tympanocentesis
Tympanocentesis (pronounced: tim-pan-o-sen-tee-sis) is a medical procedure that involves puncturing the tympanic membrane or eardrum to drain fluid from the middle ear.
Etymology
The term "Tympanocentesis" is derived from the Greek words "tympanon" meaning drum and "kentesis" meaning puncture.
Procedure
Tympanocentesis is usually performed by an otolaryngologist (ear, nose, and throat specialist) or a pediatrician. The patient's ear is first numbed with a local anesthetic. A small needle is then inserted through the eardrum to draw out fluid. This fluid can be examined under a microscope to identify any bacteria or viruses that may be causing an infection.
Indications
Tympanocentesis is typically performed when a patient has a persistent ear infection (otitis media) that has not responded to antibiotic treatment. It may also be used to relieve pressure and pain in the ear caused by a buildup of fluid.
Risks
As with any medical procedure, there are risks associated with tympanocentesis. These may include damage to the eardrum, hearing loss, and infection. However, these risks are generally low.
