title: Pleomorphic adenoma involving the stylomastoid foramen.
abstract: A rare case of an intratemporal pleomorphic adenoma is presented and the management of such a tumour is discussed. Some anatomical aspects of the facial nerve, pertinent to the pathophysiology of facial paralysis are outlined. This case demonstrates that tumour extension into the temporal bone can be resected successfully at initial surgery with excellent facial nerve functional outcome. We advocate exploration of the fallopian canal to be carried out at primary surgery and be performed by a surgeon familiar with the surgical anatomy of the intratemporal segment of the facial nerve. This approach will reduce the risk of facial nerve injury and palsy both at surgery and subsequently.
