Recently the problem of dealing with intracranial lesions of the facial nerve has been solved by Norman M. Dott, Professor of Neurosurgery at the University of Edingburgh. The idea of the operation is to by-pass the temporal bone, when that is necessary. Dott's description of the operation (Fig. 1) is as follows*: The method is quite simple. The facial nerve is exposed in the cerebello-pontile angle by a unilateral cerebellar approach. There it is severed, and to the proximal stump a nerve graft some 15 cm. long is sutured. The graft is brought out through the craniotomy opening. A tunnel for the graft is made beneath the mastoid process in the plane between the sternomastoid muscle superficially and the splenius capitis deeply, extending forward to the vicinity of the posterior surface of the parotid gland. The distal end of graft is marked by clamping a silver clip across it, and
