Figure 3

Lateral radiographs of the head. Lateral radiographs of the head were obtained in three head and neck positions. Left: extended head and neck position. Middle: neutral head and neck position. Right: flexed head and neck position. The pharyngeal diameter was defined as the shortest distance between the epiglottis and the roof of the pharynx (double-headed arrow). The metallic markers (M) were used to calculate the amplification factor as described by Cehak et al. [16].
