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 Orthodontics, 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 subjects 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 administered to parents or guardians. The cephalometric radiographs of the study subjects were traced by a single investigator, and 1 angular measurement and 11 linear measurements of hard and soft tissues were recorded. The paired Student’s t test was used to analyze the cephalometric data.

Results: Snoring children manifest a significantly narrower anterior-posterior dimension of the pharynx at the superior and most narrow widths. Snoring children also had a greater length from the hyoid to the mandibular plane.

Conclusions: Snoring children appear to present craniofacial factors that differ from those of nonsnoring children.

Key Words: cephalometry • children • snoring
