[Auriculotherapy, an anodyne technique in oncology].

Auriculotherapy is a complementary therapy recommended for the treatment of chronic pain. Effectively, the whole of the body's innervation territory is mapped out on the ear auricles, "connected" on the level of the brainstem, the relay station of all the body's sensory information. The therapy consists in inserting semi-permanent needles or localised stimulations in the auricles. The ear point is determined on the basis of neurophysiological reasoning.
