Cephalometric assessment of snoring and nonsnoring children
1Department of Orthodontics, School of Dentistry, Case Western Reserve University, Cleveland, OH 44106-4905, USA.
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.

01:20Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
