There was a significant correlation between the values of the number of papillae and blood vessel morphology. Moreover, these two parameters revealed a significant inverse correlation with gustatory function. As expected, both parameters on the affected side were significant lower than those on the unaffected side in patients.</p> </sec> <sec id="lary24031-sec-0005" sec-type="section"> <title>Conclusions</title> <p>The assessment of fungiform papillae using narrow band imaging endoscopy is easy, highly sensitive, and reliable; therefore, it might be useful as an objective examination of taste function.</p> </sec> <sec id="lary24031-sec-0105" sec-type="section"> <title>Level of Evidence</title> <p>N/A. <italic>Laryngoscope</italic>, 123:2405–2410, 2013</p> </sec> </abstract>
