Previous treatment with radiotherapy or chemoradiotherapy did not significantly affect the visibility of the hypopharynx.</p> </sec> <sec id="lary24760-sec-0005" sec-type="section"> <title>Conclusion</title> <p>The newly proposed Modified Killian's method provides an effective view of the entire circumference of the hypopharyngeal space even in patients receiving radiotherapy. This useful procedure can be performed easily and should be a part of flexible laryngoscopy for outpatients.</p> </sec> <sec id="lary24760-sec-0006" sec-type="section"> <title>Level of Evidence</title> <p>4. <italic>Laryngoscope</italic>, 124:2526–2530, 2014</p> </sec> </abstract>
