[Endoscopic ear surgery. Initial evaluation].

The authors describe an endoscopic procedure of surgery of the ear and report on their experience in surgery for cholesteatoma with a closed procedure in the first step and the systematic second-look. The use of such a system is an essential complement for the surgical microscope to control some regions of the middle ear such as the sinus tympani. The study deals with 72 cases of cholesteatoma operated successively. The number if residual cholesteatomas is analyzed. The merits of controlling assemblies in some ossiculoplasties with an endoscopic system are discussed.
