Effects of head posture on the oral, pharyngeal and laryngeal axis alignment in infants and young children by magnetic resonance imaging

“…The quantification of visualization conditions with angle measurements, as we attempted to do, can be criticized. Particularly anatomical axis alignment and laryngeal visualization are not equivalent (27–30). The term ‘line of vision’, as defined by Adnet et al.…”
