[Tumors at the skull base]

Tumors at the skull base, usually benign, present diagnostic and therapeutic challenges. Thus they necessitate close cooperation between the departments of otolaryngology, head and neck surgery, neurosurgery, anesthesia and diagnostic radiology. We therefore set up a special team for diagnosis and treatment of such cases. 2 representative cases of benign tumors at the skull base operated through the combined middle cranial fossa--infratemporal fossa approach are presented in detail.
