[Instrument for cryogenic surgery of subatrophic and atrophic rhinitis and pharyngitis].
To treat cryogenically the nasal and pharyngeal mucosa an instrument has been devised in which the supply of cold carrier is regulated by changing pressure in the reservoir and by using interchageable needles of different diameter. The direction of the cold carried stream is changed depending upon the needle chamfer angle and the arrangement of holes in its wall. The procedure used in applying cryogenic action is simple and may be used in treating outpatients.
