ABSTRACT
A cryogenic ENT applicator, model K-22 has been designed and recommended for clinical use. The applicator unit comprises an independent container filled with liquid nitrogen and connected to a cooling tip 2 mm in diameter by capillary tubes. The applicator is used for the destruction of neoplasms by cryogenic action in hardly accessible places in the aural, pharyngeal and nasal cavities. The applicator is easy to sue, has a small size and weight and allows a good survey of the operative field. It can be used in hospital and in outpatient clinics.

A cryoprobe with an interchangeable container (vessel) holding the cryoprobe has been designed, this enabling it to dispense with the use of hoses to deliver the coolant to and remove it from the Dewar vessel and the vacuum pump. The cryogenic action provided for by a single ampoule lasts 5 minutes. The small diameter of the cryoprobe makes for a minimal traumatization of the surrounding structures, while the absence of connecting hoses makes for its easy handling.
