Methylene Blue Video Contact Endoscopy Enhanced with SPIES Filters in Early Detection of Malignancies of the Vocal Fold

摘要

Methylene blue video contact endoscopy was imagined for the first time in the early '70s by a gynecologist named Hamou. He was the first one to perform contact colposcopy using methylene blue staining. Because of the poor medical optic technology at that time the method was abandoned. Prof. Mario Andreea and Oscar Diaz preformed in 1994 the first video contact endoscopy of the vocal fold. We propose a new way to enhance the video contact endoscopy's power to detect early malignancies of the vocal fold using SPIES software filters. The method will be be critically analyzed.
