Trochlear nerve palsy as a complication of trigeminal radiofrequency rhyzolysis

Abstract

We report a patient with right trochlear nerve palsy after percutaneus radiofrequency trigeminal rhizolysis involving the ophthalmic division of the right trigeminal nerve. Of the postoperative complications of percutaneous radiofrequency trigeminal rhizolysis, extraocular nerve injuries are uncommon and the sixth nerve is the frequently affected one. This is a case report of isolated trochlear nerve palsy as a complication of percutaneous radiofrequency trigeminal rhizolysis.
