Figure 2: A representative image depicting the influence of tongue size on modified Cormack-Lehane grade (MCLG). In image b, the large tongue (in comparison to image a) is obscuring the view of the glottis, thereby increasing MCLG during direct laryngoscopy. Thus, a large, posteriorly protruding tongue increases MCLG and is likely to hinder the smooth passage of the TEE probe into the esophagus. Abbreviations: G: glottic opening; black line: depicts oropharyngeal axis during laryngoscopy
