In this book we have tried to collect the state of the art of nasal and paranasal sinus surgery, deepening the most modern techniques and addressing every single pathology with great dedication. In the first chapter, thanks to the help of Professor Enrique Perello, leader of ENT surgery in Spain and with an international reputation, we tried to trace the history of nasal surgery. We found photos of ancient treatises, analyzing the origins of some techniques, still used but perfected with the help of technology. In the following chapters, we have dealt with the basic surgery of the nose and paranasal sinuses, with evident help on the septal endoscopic part by Professor Andrea Gallo, director of the Polo Pontino of the La Sapienza University in Rome. The chapters on oroantral communications and odontogenic sinusitis were written by Professor Cosme Gay-Escoda, leader in the maxillofacial and oral cavity surgery sector throughout Spain. The chapter on inverted papillomas was written by the professor of the University of Genoa Frank Rikki Canevari, a surgeon of national and international fame, expert on the nasal cavities. We wrote a chapter on dacryocistorinostomy, with the help of Professor Maurizio Catalani, of the University of Turin and in collaboration with a team of ophthalmologists led by professors Meduri, Aragona and doctor Migliardi. We thank the whole ENT team of the University of Palermo, led by Professor Gallina, for the chapter on the complications of endonasal surgery. We received special help from the team of the Insubria University of Varese, led by professors Bignami and Castelnuovo, world leaders in this type of surgery. They wrote the chapters on rhino-liquor fistulas and on the treatment of nasal tumors, giving us the precious images of their most interesting clinical cases. Thanks to external contributions, this book can be considered a handbook for nose surgery, updated to the most modern surgical techniques in use and with an analysis of the possible future developments of this type of surgery.
