Differences between the infant and adult airway. Nicole W. Pelly, MD. The infant airway differs from the adult airway in structure and in functionality (Figure 192-1).Understanding these differences is important for airway management and, when necessary, for successful tracheal intubation of neonatal, infant, and pediatric airways. Pediatric Airway Anatomy; Obligate Nasal Breathers Large Tongue Large Occiput Larynx and Trachea are funnel shaped Vocal Cords slant anteriorly Larynx located higher in neck (at C4 vs. C6 in adults) Narrowest part of the pediatric airway is at cricoid cartilage (until age 5). In adults the narrowest part is at the glottis opening.
