Resolution of Sixth Nerve Palsies Following Treatment with Primary Fractionated Stereotactic Conformal Radiotherapy of Petroclival Meningiomas (.pdf)

Petroclival meningiomas are a recognised cause of sixth nerve palsy. Despite their benign pathology, petroclival meingiomas remain a surgical challenge due to the complex anatomy, close association with critical neurovascular structures and difficult exposure of this region.Fractionated Stereotactic Conformal Radiotherapy (FSCRT) is a process whereby radiotherapy is delivered via a fractionated schedule utilizing nonrigid immobilization, thereby providing the precision of stereotaxy while allowing adjacent normal structures to repair sublethal damage.To our knowledge there are no studies on the role of FSCRT on petroclival meningiomas.
