[Intracranial schwannomas of the cranial nerves. The acoustic nerve excluded].

The schwannomas of the cranial nerves (except the IId and VIIIth nerves) are known to be infrequent although progress in diagnosis of these tumors have been obtained by C.T. scan. We report twelve cases involving the facial nerve and five cases of the caudal nerves that were developed into the foramen jugulare, and two cases of trigeminal schwannomas. One may suspect these tumors in presence of any minimal, unilateral defect of otological, facial, and pharyngo-laryngeal functions. The surgical approach to the tumors depends on both its location and symptomatology.
