Five pediatric airway surgeons evaluated the three-dimensional models for determining the surgical approach, incision location and length, graft length, and need for single or double-stage surgery of seven children (median age 4.4\u2009years, M:F ratio 4:3). They rated the importance of the three-dimensional model findings compared to the direct laryngoscopy videos and CT findings for each domain on a validated Likert scale of 1\u20135. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> The mean rating for all domains was 3.6\u2009\u00b1\u20090.63 (\u201cmoderately important\u201d to \u201cvery important\u201d), and the median rating was 4 (\u201cvery important\u201d). There was full agreement between raters for length of incision and length of graft. The between-rater agreement was 0.608 (\u201cgood\u201d) for surgical approach, 0.585 (\u201cmoderate\u201d) for incision location, and 0.429 (\u201cmoderate\u201d) for need for single- or two-stage surgery. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> Patient-specific three-dimensional printed models of children's upper airways were scored by pediatric airway surgeons as being moderately to very important for preoperative planning of open laryngotracheal surgery. Large\u2013scale, objective outcome studies are warranted to establish the reliability and efficiency of these models. <\/jats:p><\/jats:sec><jats:sec><jats:title>Graphical
