[The rehabilitation of the tongue in hypoglossal-facial anastomosis]

End to end hypoglossal-facial nerve anastomosis (tt HFA) is a traditional technique for rehabilitation of facial palsy. The sacrifice of the hypoglossal nerve generates a paralysis and an atrophy of the tongue which is thought to lead to speech, chewing and swallowing disorders. In a previous study, we demonstrated that tt HFA does not lead to speech disorders (Gatignol et al 2003). OBJECTIVES: In this work, we were interested in the functional consequences of the lingual atrophy and in the
