This book offers a highly didactic presentation and explanation of endoscopic surgery with video monitoring. It is a truly essential introduction to video-monitored surgery. This technique, complementary to microsurgery, applies not only to the surgery of cholesteatoma and retraction pockets, but also to other lesions of the middle ear, and has greatly reduced the incidence of residual cholesteatoma. It offers further advantages in the second operative stage of monitoring tympanoplasty by the closed technique, allowing minimal routes of cutaneous surgical approach. This manual will guide the ENT surgeon in learning a new technique and will also, by means of effective color illustrations, demonstrate the various stages and the results which can be expected.
