OBJECTIVES: To present electronic videoendoscopy of the larynx with digital image processing and to discuss this endoscopic technique from the standpoint of diagnostic usefulness of @entity75 . STUDY DESIGN: Electronic videoendoscopic evaluation of @entity75 with digital image processing. METHODS: Seventy @entity1 underwent electronic videoendoscopy without digital image processing and, subsequently, with the digital image processing function. Of these, 15 @entity1 with white lesion of the vocal fold and @entity25364 were assessed in the study. Clinical assessments made before enhancement of digital image processing function were compared with those after enhancement in 15 @entity1 . RESULTS: Of the 15 @entity1 observed, the clinical diagnoses of two @entity1 were changed after enhancement. Both @entity1 underwent endolaryngeal microsurgery with histopathological examination of the removed lesions, which confirmed the definitive diagnosis. The clinical diagnoses of both @entity1 after enhancement were compatible with histopathological diagnoses. CONCLUSIONS: The enhanced color images provided by this system are superior in both quality and resolution to those obtained by conventional flexible fiberoptic endoscopy with a video camera. This system should be a valuable tool for the diagnosis of @entity75 .
