[Tractotomy and partial nucleotomy as a form of therapy in refractory pain of the trigeminal nerve and cancer pain in the head and neck area].
Persistent trigeminal neuralgia, herpes zoster neuralgia of the first division of the trigeminal nerve and pain caused by cancer situated in the head and neck pose frustrating problems for patients and physicians. Tractotomy and/or partial vertical nucleotomy of the subnucleus caudalis nervi trigemini offers a logical approach to the treatment of such pain, since these structures contain fibres of the Vth nerve, as well as the somatosensory fibres of the VIIth, IXth and Xth nerve. Tactile and some thermal sensitivity of the face is preserved and anaesthesia dolorosa and keratitis neuroparalytica is avoided. Over the past 30 years 370 patients with therapy-refractory trigeminal pain, pain due to cancer of the head and neck and herpes zoster trigeminal pain were treated by means of tractotomy (personal series of V. Grunert), including 30 patients who underwent partial vertical nucleotomy. The mean age of the patients was 68 years (range 54-84 years). The mortality in this series was 0.9% (4 patients; one operative mortality due to air embolism, one postoperative cardiac failure following myocardial infarction and two intracerebral haematomas). 60% of the patients with persistent trigeminal neuralgia were pain-free and 28% improved, whereas 12% were unchanged or suffered from recurrent pain. Of the patients with cancer who complained of pain derived from the Vth, VIIth, IXth and Xth nerve, 40% demonstrated marked pain relief and 60% showed no improvement. Tractotomy and partial vertical nucleotomy offer a valuable method in experienced hands for relieving pain where other methods have failed.
