Lateral approaches

John D. Day, Griffith R. Harsh, Thomas W. Morris

Research output: Chapter in Book/Report/Conference proceedingChapter


Select chordomas and chondrosarcomas have extensions to the posterior cavernous sinus and to the petrous apex. These lesions may be best approached by an anterior transpetrosal approach, either alone or in combination with an anterolateral or a posterolateral technique. The anterior transpetrosal technique may be performed either via an intradural or an extradural technique. These techniques are described in detail for a lateral approach to resect these lesions from the posterior cavernous sinus, the medial cerebellopontine angle, and the petroclival regions.
