title: Transoral transclival removal of anteriorly placed meningiomas at the foramen magnum.
abstract: Anteriorly placed meningiomas at the level of the foramen magnum are rare, are difficult to diagnose, and present technical problems for a conventional posterior fossa removal. The authors describe the successful transoral transclival excision of two such tumors. Cerebrospinal fluid (CSF) fistula can be avoided by dural repair using a thrombin glue and long term CSF diversion. This modification enables the transoral route to be considered for anteriorly placed intradural lesions.
