[Cryogenic instruments for the treatment of head and neck neoplasms]

Experience gained with the treatment of head andneck tumours with different cryogenic instruments, whose size and shape varied within a wide range, helped choose and recommend for performing a large number of operations as instrument, the length and diameter of whose working part measure 200 mm and 6 mm respectively, with the length of the freezing tip of 25 mm and the angle of its inclination to the axis--100--120 degrees. The presence of a warmer and of a holding handle makes it easy to handle.
