[Narrow band imaging for early diagnosis of epithelial dysplasias and microinvasive tumors in the upper aerodigestive tract]. HNO. 2015 Dec 17; Authors: Arens C, Betz C, Kraft M, Voigt-Zimmermann S Abstract The various stages of tumor growth are characterized by typical epithelial, vascular, and secondary connective tissue changes. Narrow band imaging (NBI) endoscopy is a minimally invasive imaging technique that presents vascular structures in particular at a higher contrast than white light endoscopy alone. In combination with high-resolution image recording and reproduction (high-definition television, HDTV; ultra-high definition, 4K), progress has been made in otolaryngological differential diagnostics, both pre- and intraoperatively. This progress represents an important step towards a so-called optical biopsy. Flexible endoscopy in combination with NBI allows detailed assessment of areas of the upper aerodigestive tract which are difficult to assess by rigid endoscopy. Papillomas, precancerous, and cancerous lesions are characterized by epithelial and connective tissue changes, as well as by typical perpendicular vascular changes. Systematic use of NBI is recommended in the differential diagnosis of malignant lesions of the upper aerodigestive tract. NBI also convinces by a significant improvement in pre- and intraoperative assessment of superficial resection margins. In particular, the combination of NBI and contact endosc...
