Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="abs1-1" sec-type="section"> <title>Background</title> <p>Oncologic resection of the nasopharynx is challenging due to its complex and deep‐seated nature. We aimed to illustrate the anatomic landmarks of endoscopic nasopharyngectomy and design a surgical training model that could facilitate learning of this technique.</p> </sec> <sec id="abs1-2" sec-type="section"> <title>Methods</title> <p>An endoscopic endonasal dissection of the nasopharynx was completed in fresh cadaveric specimens under conditions similar to those of our operating suite. Digital data from a high‐resolution CT scan were imported to an image guidance system to be used during the dissections.</p> </sec> <sec id="abs1-3" sec-type="section"> <title>Results</title> <p>We expanded the sinonasal corridor, harvested a contralateral nasoseptal flap, and exposed the pterygopalatine and infratemporal fossae. A detailed anatomic dissection of the nasopharynx was correlated to multiplanar images provided by the image guidance system, highlighting appropriate bony, neural, and vascular landmarks.</p> </sec> <sec id="abs1-4" sec-type="section"> <title>Conclusions</title> <p>Understanding the anatomy‐based endoscopic modular approaches facilitates planning and safe execution of an oncologic nasopharyngectomy. Clinical experience remains mandatory because anatomic models fall short of clinical scenarios. © 2012 Wiley Periodicals, Inc. © 2012 Wiley Periodicals, Inc. Head Neck, 2013</p> </sec> </abstract>
