The Pediatric Airway

  • R. Cleveland


During infant respiration, not only the diameter but also the shape of the trachea may change dramatically. On expiration, the trachea often assumes a buckled configuration that deviates in an angular manner away from the side of the aortic arch at the level of the thoracic inlet. In addition, angular buckling associated with a widening of the pre-vertebral, retropharyngeal, and retrolaryngeal soft tissues may occur posteriorly and inferiorly at the thoracic inlet [1]. In fact, the width of the prevertebral soft tissues may increase to at least twice the AP width of the cervical vertebral bodies on expiration. This soft-tissue fullness may also be noted with flexion of the neck. As the infant matures, the amount of soft tissue decreases.
