Controlled thermocoagulation of trigeminal ganglion and rootlets for differential destruction of pain fibers: facial pain other than trigeminal neuralgia.

I describe the results of retrogasserian differential lidocaine block to aid in the selection of patients for a differential thermal lesion in the trigeminal ganglion and rootlets. This procedure temporarily duplicates the state of analgesia without anesthesia one seeks to make permanent with the radiofrequency heating. The results of this heating procedure are described in the treatment of 71 patients with facial pain of cancer, postherpetic, periodic migrainous neuralgia, acromegaly, trigeminal neuropathy, central pain, post-traumatic facial neuralgia, and atypical facial neuralgia.

"Phantom" sensations following intraspinal injury.

The sensations associated at times with neural lesions in the spinal canal may have the following features and phases: 1) early anosognosia, i.e. lack of awareness of disability; 2) initial stimulation; 3) illusion of amputation; 4) disappearance of that illusion and 5) grotesque sensations. Detailed features of the phantoms such as changes in their size, position, and vividness as well as tactics evoking changes in the sensations are recorded. The special situations are described in which paraplegia is accompanied by actual amputation, or there is a phantom of an upper limb after avulsion of the brachial plexus or after extensive posterior rhizotomy. Finally phantoms associated with incomplete lesions of the cord are analyzed and the basis presented for concluding that a lesion of an ipsilateral posterior column is responsible for the phantom experience in cord lesion.
