Study objective: To determine the differences in
craniofacial cephalometric variables between snoring and nonsnoring
Setting: Case Western Reserve University Dental School,
Department of Orthodontics, and local Cleveland orthodontic private
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%
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.
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
Conclusions: Snoring children appear
to present craniofacial factors that differ from those of nonsnoring
