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 laryngeal lesions. Study Design Electronic videoendoscopic evaluation of laryngeal lesions with digital image processing. Methods Seventy patients underwent electronic videoendoscopy without digital image processing and, subsequently, with the digital image processing function. Of these, 15 patients with white lesion of the vocal fold and laryngeal neoplasms were assessed in the study. Clinical assessments made before enhancement of digital image processing function were compared with those after enhancement in 15 patients. Results Of the 15 patients observed, the clinical diagnoses of two patients were changed after enhancement. Both patients underwent endolaryngeal microsurgery with histopathological examination of the removed lesions, which confirmed the definitive diagnosis. The clinical diagnoses of both patients 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 laryngeal lesions.
