Abstract

Early detection of cancerous lesions of the larynx may be the best method of improving patient quality of life and survival rates. New in-vivo technologies may be of great clinical relevance in improving the accuracy of sampling during microlaryngeal surgery. Optical coherence tomography (OCT) is an optical imaging technique that clearly identifies basement membrane violation caused by laryngeal cancer. With a microscope-based spectral domain OCT (SD-OCT) we reached in vivo a fairly accurate assessment of benign and dysplastic laryngeal lesions. Recent improvements in OCT technology have led to the development of high-speed OCT systems displaying millions of pixels per second. These systems allow non-contact real-time imaging of large sections of laryngeal tissue. Polarization contrast OCT (PS-OCT) may provide additional information about the lamina propria of the true vocal cord because of the birefringence of connective tissue. We present microscope-based high-speed SD-OCT images with and without polarization contrast and 3D volumes of selected laryngeal pathologies in order to demonstrate our current concepts for the intended intraoperative application. High-speed SD-OCT and polarization contrast can also be complemented by our recently developed rigid confocal endoscopic system to obtain cellular and sub-cellular information about the tissue. Further perspectives will be presented.
