Pathogenesis and surgical treatment of neurovascular primary headaches

The “neurovascular primary headaches” are syndromes also pertinent to otorhinolaringology when CT demonstrates a reduced volume of the “ethmoidosphenoidal subcribriform chamber” according to the endo-exocranial hemoangiokinetics of this area. It is emphasized that in drug-resistant headaches recovery or consistent definitive improvement can be achieved only after surgical correction of certain anatomical parameters (P. Bonaccorsi, V. J. Novak, S. Hoover). Bonaccorsi and Novak independently identified the actual pathophysiologic mechanism and trigger zone (“dysmorphism”) for various types of neurovascular primary headaches.
