Lateral cricoid cuts as an adjunctive measure to enlarge the stenotic subglottic airway: an anatomic study.
The technique of laryngotracheoplasty, with an anterior approach, with or without a posterior cut, and with or without anterior or posterior cartilage grafts, has been described previously. On occasion, a severely stenotic subglottis or aberrant shape to the cricoid cartilage makes division of the lateral aspects of the cricoid cartilage desirable. ⋯ The distance was very close in the fetal larynx (measuring 1.5 mm in the 23rd week of gestational age), with an increase in dimension in the infant and child, increasing to a distance of over 1 cm in the mature adult. The clinical significance of this relationship to proposed cuts of the lateral cricoid in different age groups is discussed.
