This book fills a gap in the field of the cranio-orbital lesions, as it deals only with mass lesions involving both the intracranial and intra-orbital compartments. The surgical anatomy, diagnosis, surgical approaches and specified pathological mass lesions are described in detalis.

The book includes four parts. Part 1,  is devoted to the surgical anatomy of the orbital region. Part 2  to the clinical and neuroradiological examination of the cranio-orbital mass lesions. Part 3 discusses the surgical approaches, both trans-cranial and transorbital, and microscopic and endoscopic, focusing on  the surgical techniques, their indications, advantages, limitations and complications. Finally, part 4  discusses the single pathological mass lesions, their anatomo-clinical and radiological aspects and the best surgical approaches.       

Aim of this book is to illustrate the best surgical approaches according to prevalent intracranial or intra-orbital extension and the type of the mass lesions.

Giulio Bonavolotà is professor emeritus of Ophthalmology at the University Federico II of Naples. He founded and directed the Center for Orbital Pathology of the same University, which is still the reference center for many practitioners in Italy. He deals in particular with the treatment of tumors, soft mass lesions, fractures and traumatic patologies of the orbit, eyelid surgery and ocular complications of Basedow-Graves' disease. His personal surgical series of orbital and cranioorbital tumors is among the top 5 in the world. He collaborates as a reviewer with numerous scientific journals and is the author of hundreds of publications in international journals . He is also Honorary President of the Italian Society of Ophthalmoplastic Surgery and Past President of the European Society of Ophthalmoplastic and Reconstructive Surgery.

 Francesco Maiuri is Professor of Neurosurgery, Director of the Neurosurgical Program and director of the Residency Program in Neurosurgery at University of Naples Federico II. He focused his scientific and surgical activity on the diagnosis and management of the tumors of the nervous system, mainly meningiomas, and to the skull base and cranioorbital pathologies. He was president of the Italian Association of Neuro-Oncology (AINO). He is author of about 300 scientific publications, mainly in international journals with high impact factor and editor of several neurosurgical books.

 Giuseppe Mariniello is specialized  in Neurosurgery and obtained a  PhD in Orbito-Maxillofacial Pathology and Surgery. He is  Associate Professor of Neurosurgery at University of Naples Federico II and at Residency Program in Neurosurgery of the same university. He spent four years at the neurosurgical center of Lubiana, directed by professor Vinko Dolenc, where he improved his experience in the surgical management of skull base and cranio-orbital tumors, mainly spheno-orbitalmeningiomas. He is author of many scientific publications on international journals with high impact factor, mainly focusing the skull base meningiomas and schwannomas.
