Cryoextraction (medicine)
Cryoextraction (pronounced: cry-o-ex-trac-tion) is a medical procedure that involves the use of extreme cold to remove or destroy tissue.
Etymology
The term "Cryoextraction" is derived from the Greek words "kryos" meaning cold, and "extraction" which is derived from the Latin word "extrahere" meaning to draw out.
Procedure
In medicine, cryoextraction is often used in ophthalmology to remove cataracts from the eye. The procedure involves the use of a cryoprobe, a device that is cooled to extremely low temperatures, to freeze the lens of the eye. Once the lens is frozen, it can be extracted from the eye.
Cryoextraction is also used in pulmonology to remove foreign bodies from the airways. The cryoprobe is used to freeze the foreign body, which can then be removed with the probe.
Advantages and Disadvantages
The main advantage of cryoextraction is that it is less invasive than other surgical procedures. It also causes less damage to surrounding tissues. However, the procedure does have some risks, including infection, bleeding, and damage to the eye or airways.
