This innovative procedure can be considered an important tool during diagnosis, treatment, and follow‐up of patients with precancer and cancer of the larynx and hypopharynx.</p> </sec> <sec id="lary25124-sec-0006" sec-type="section"> <title>Level of Evidence</title> <p>1b. <italic>Laryngoscope</italic>, 125:1600–1606, 2015</p> </sec> </abstract>
