Hypoglossal-facial anastomosis (HFA) is a cross-over between the proximal stump of the hypoglossal nerve (XII) and the distal one of the facial nerve (VII). The hypoglossal axons regrow within the sheaths of facial fibres, allowing the progressive reinnervation of the facial muscles. This model is interesting to study some mechanisms of plasticity of the nervous system for several reasons: 1) It is a quite simple and reproducible model of pathophysiological state. It allows the study of 2) the modifications of the nervous system induced by the HFA, both upwards and downwards to the lesion and 3) the modifications of reflex activities involving intrapontine connections such as the blink reflex. The electrophysiological features of the trigemino-facial (TF) and trigemino-hypoglossal (TG) connections demonstrated that a central reorganisation of the blink reflex (BR) was induced by HFA: the afferent volleys of the TF and TH reflexes elicited by cutaneous and mucosal trigeminal afferents respectively have been shown to project onto common interneurones located within the trigeminal principal sensory nucleus. A long-term prospective study showed: 1) a reinnervation of the facial muscles by the hypoglossal axons is a necessary perequisite for the central reorganisation of BR, 2) a hyperinnervation of the facial muscles by the hypoglossal axons, 3) a transient and regressive cross-innervation of paralyzed face by the healthy contralateral facial nerve.
