[Partial vertical nucleotomy. A neurosurgical intervention in some forms of therapy-resistant facial neuralgia].

The partial vertical nucleotomy is presented as a new neurosurgical method for the treatment of therapy-resistant pain in the spreading area of the N. trigeminus. Strict indications are laid down which are mainly restricted to therapy-resistant pain in the above mentioned spreading area in the presence of diffusely growing malignant tumours, after traumas and infections and predominantly in forms of idiopathic trigeminal neuralgia that has been treated without any results over a period of many years. In the experimental part of the article; material and method as well as results of anterograde transport on the efferent trigeminal pathways in rabbits by means of horseradish peroxi- dase (HRP) and its representation by means of tratramethylbenzidine (TMB) are discussed. Furthermore fibre preparations of the tractus and nucles spinalis nervi trigemini and the radiating fibres of the Nervus vagus are shown.
