It is not safe when performed in the rostral cervical segments for intractable pain in the upper extremities, owing to the danger of respiratory failure. To avoid this complication posterior rhizotomy has been suggested, but this is undesirable since the upper extremity then becomes anesthetic and useless. This procedure is of more value for the relief of severe pain in the neck. For pain in the arm, the neck and the face, a combination of section of the fifth and ninth cranial nerves and posterior cervical rhizotomy becomes a formidable procedure, especially in a patient who is already debilitated.
