Structured abstract Authors – Heliövaara A, Hurmerinta K Objectives – To evaluate cephalometrically the craniofacial, pharyngeal and cervical morphology in children with CATCH 22, and to compare and quantify the findings with age‐ and sex‐matched controls. Design – A retrospective case–control study. Setting and Sample Population – Forty‐one children (20 girls) with CATCH 22 were compared with age‐ and sex‐matched controls from lateral cephalograms taken at the mean age of 8.5 years (range 5.8–12.9). The deletion of 22q11 was verified by fluorescence in situ hybridization techniques. Thirteen of the children with CATCH 22 had palatal clefts. Outcome measure – Linear and angular measurements were obtained from lateral cephalograms. A Student's t ‐test and a paired Student's t ‐test were used in the statistical analysis. Standard deviation scores (SDS) were calculated to quantify the variation. Results – Children with CATCH 22 had obtuse cranial base angles and long anterior cranial bases. Their faces were long with increased facial convexity. The maxillae were long but both jaws were retrognathic and the lower jaws posteriorly diverged. The pharynges were wide in the nasopharyngeal area and narrow in the hypopharyngeal area. The development of the hyoid bones was delayed, and hyoid bone and atlas lengths were reduced. The morphology of the children with CATCH 22 with and without a palatal cleft was similar. Despite several statistically significant differences between the children with CATCH 22 and the controls, the SDS did not exceed ±2 for any of the measurements. Conclusion – Children with CATCH 22 have several minor distinctive morphological features in the craniofacial, pharyngeal, and cervical areas.
