[A "mother-and baby scope-optic" for middle ear endoscopy (author's transl)].

A new optic system for middle ear endoscopy is presented. It was developed in collaboration with Ltd. Wolf during the past 2 years. Via a bigger optic a smaller optic can be introduced under control. Through the new optic system it is possible to get a good survey about all "hidden places" in the middle ear. The optic can be used for pre- and intraoperative diagnostic.
