Cranial base surgery involves treatment of the congenital, vascular, neoplastic, endocrine and traumatic lesions involving the basi cranium. This surgery is the brainchild of three specialties: Craniofacial surgery, Neurosurgery and neuro-otology and was championed by three pioneers: Tessier, Dandy and House. Anatomically the skull base is divided into three subdivisions. The anterior skull base, the lateral skull base and the posterior or extreme lateral skull base.
