Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="hed23452-sec-0001" sec-type="section"> <title>Background</title> <p>Optical coherence tomography (OCT) allows tissue histologic‐like evaluation, but without tissue fixation or staining. We investigated OCT images from tissues obtained at thyroid and parathyroid surgeries to provide a preliminary assessment as to whether these images contain sufficient information for recognition and differentiation of normal neck tissues.</p> </sec> <sec id="hed23452-sec-0002" sec-type="section"> <title>Methods</title> <p>Normal tissues were obtained from patients undergoing surgical treatment. Two new‐generation OCT systems, including optical frequency domain imaging (OFDI) and μOCT, were compared to representative hematoxylin‐eosin histology.</p> </sec> <sec id="hed23452-sec-0003" sec-type="section"> <title>Results</title> <p>Thyroid, fat, muscle, lymph nodes, and parathyroid tissues were evaluated. Histologic‐like microscopic characteristics sufficient for tissue type identification was realized using both systems for all tissue types examined.</p> </sec> <sec id="hed23452-sec-0004" sec-type="section"> <title>Conclusion</title> <p>This pilot study demonstrated that new‐generation OCT systems are capable of recognizing and differentiating neck tissues encountered during thyroid and parathyroid surgeries. Further advances in OCT miniaturization and development of sterile intraoperative probe formats may allow OCT to offer an intraoperative "optical biopsy" without fixation, staining, or tissue resection. © 2013 Wiley Periodicals, Inc. <italic>Head Neck</italic> 36: 1329–1334, 2014</p> </sec> </abstract>
