Abstract
Narrow band imaging (NBI) is an endoscopic method using filtered wavelengths in detection of microvascular abnormalities associated with preneoplastic and neoplastic changes of the mucosa. The aim of the study is to evaluate the value of NBI endoscopy in the diagnosis of laryngeal precancerous and early stages of cancerous lesions and to investigate impact of NBI method in 'prehistological' diagnostics in vivo.
One hundred patients were enrolled in the study and their larynx was investigated using white light HD endoscopy and narrow band imaging between 6/ 2013- 10/ 2014. NBI endoscopy is a promising optical technique enabling in vivo differentiation of superficial neoplastic lesions.
These results suggest endoscopic NBI may be useful in the early detection of laryngeal cancer and precancerous lesions.
