[Surgery of cancer pain. Section of the IX and V nerves in the ontocerebellar space, section of Andersch's ganglion and Jacobson's verve. Indications and results].

The authors describe their experience involving 30 patients treated surgically for stubborn algesia during the development of cancers of the face and neck. Sectioning Jacobson's nerve which they suggested for 72 cases exclusively or mainly involving otalgia especially where the tumours was tonsillar, proved of great therapeutic value and took little toll of the patients. - Resection of Andersch's ganglion, difficult and often ineffective, should not be attempted. - On the other hand, when there is stubborn pharyngeal pain with otalgia, sectioning the IXth is remarkably successful. Likewise, where there is pain in the face or tongue and the floor of the mouth which fails to respond to opiates, partial microcoagulation of the pre-pontile root of the trigeminal nerve is an excellent solution. - Neurotomies of the IXth and the Vth, carried out in the cerebellopontile angle, are operations with simple sequelae. They have the outstanding advantage of permanently relieving the pain of these unfortunate patients.
