    First Use of Long-Range Optical Coherence Tomography to Image Airway Structure in Awake Children

    Objectives: Identifying the appropriate operation(s) for children with sleep-disordered breathing (SDB) remains a challenge, and current imaging modalities have major shortcomings. We have pioneered the use of long-range optical coherence tomography (LR-OCT) to provide real-time images of the upper airway (UA) during sleep and wakefulness. Here we present our first use of LR-OCT to image the UA of awake children. (1) Understand how LR-OCT produces high-resolution structural images by acting as an optical range-finder. (2) Recognize how LR-OCT can identify strictures and real-time collapse of the airway. Methods: This study builds upon our experience using LR-OCT to image 58 ...
