Cephalometric assessment of snoring end nonsnoring children

Study objective: To determine the differences in craniofacial cephalometric variables between snoring and nonsnoring children. Design: Cross-sectional. Setting: Case Western Reserve University Dental School, Department of Ortho dontics, and local Cleveland orthodontic private practices. Patients: Twenty-eight snoring and 28 nonsnoring children between the ages of 7 years and 14 years. Nonsnoring subjects were matched to snoring subjec ts by age, sex, and ethnicity (mean [+/- SD] age, 10 +/- 2 years; 82% white , 64% female). Interventions: None. Measurements: Snoring was assessed using a sleep behavior questionnaire adm inistered to parents or guardians. The cephalometric radiographs of the stu dy subjects were traced by a single investigator, and 1 angular measurement and 11 linear measurements of hard and soft tissues were recorded. The pai red Student's t test was used to analyze the cephalometric data. Results: Snoring children manifest a significantly narrower anterior-poster ior dimension of the pharynx at the superior and most narrow widths. Snorin g children also had a greater length from the hyoid to the mandibular plane . Conclusions: Snoring children appear to present craniofacial factors that d iffer from those of nonsnoring children.
