Skull base chordoma with cavernous sinus involvement. Partial or radical tumour-removal?
A report of eight cases of skull base chordoma is given and the related literature reviewed. From disappointing experience with incomplete tumour removal and radiation the conclusion is drawn, that radical tumour removal at the first attempt should be strived for, even if the operative risk seems to be high. Cavernous sinus invasion should not be a reason to omit operation. Loss of function of one eye appears to be justified if radical tumour removal can be achieved. Possibly, the operative strategy can be improved by combining a frontal transbasal with a frontotemporal subtemporal approach, thus creating a chance for preservation of oculomotor function even in patients whose tumour has invaded the cavernous sinus region.
