[Modern photo-endoscopic techniques for examination of the nasopharynx (author's transl)].

Advances in electrotechniques and optics in the last years have led to the use of fiberoptic endoscopes in the examination of the nasopharynx. A modified photo-endoscopic method is reported, utilizing a Hopkins' lens system which is introduced intraorally. A robot-reflex camera with variable optics and focal distance is used for photographic documentation of nasopharyngeal findings. The efficiency of the method is demonstrated by selected clinical examples.
