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. Feb 07, · 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 ).Understanding these differences is important for airway management and, when necessary, for successful tracheal intubation of neonatal, infant, and pediatric airways.
The pediatric trachea is much more pliable and smaller in diameter than the adult and has immature tracheal rings. Eckstein M. Out-of-hospital pediatric airway management. Ann Emerg Med 44(2. May 02, · For example, assuming that the diameter of the cricoid ring in the infant is 4 mm and the diameter of the adult cricoid ring or trachea is 8 mm, 1 mm of edema circumferentially within the airway (i.e., reduction of the diameter of the airway by 2 mm) would decrease the cross-sectional area of the airway in the infant by approximately 75% (to 2 mm), whereas the adult .
