Insights
Children with obstructive sleep apnea (OSA) exhibit distinct craniofacial differences, including mandibular length and airway size. These skeletal and soft tissue variations are key indicators for pediatric OSA.
Area of Science:
- Craniofacial Anatomy
- Pediatric Sleep Medicine
- Medical Imaging
Background:
- Pediatric obstructive sleep apnea (OSA) is linked to craniofacial abnormalities.
- Understanding these anatomical predispositions is crucial for diagnosis and treatment.
Purpose of the Study:
- To compare cephalometric measurements of skeletal, dental, and soft tissue structures in children with and without OSA.
- To identify craniofacial features associated with pediatric OSA.
Main Methods:
- Lateral head radiographs of 15 children with OSA and 15 matched controls were analyzed.
- Fifty-six cephalometric measurements assessed skeletal, soft tissue, and airway dimensions.
Main Results:
- Children with OSA showed a smaller SNB angle, increased PG/NB value, and greater anterior lower facial height.
- The hyoid bone was positioned lower, and adenoid and tonsil sizes (A and T/P) were larger in the OSA group.
Conclusions:
- Significant craniofacial differences, including mandibular length, facial height, hyoid position, and airway size, distinguish children with OSA from controls.
- These findings highlight specific anatomical factors contributing to pediatric OSA.
Objective:
This study aims to analyze differences in the skeletal, dental, and soft tissue components of craniofacial structure predisposing to the pediatric obstructive sleep apnea, by a comparison of the cephalograms between children with obstructive sleep apnea (OSA) and controls.
Materials And Methods:
The study enrolled a total of 30 children who were composed of the following two groups: 15 OSA patients and 15 controls. The two groups were strictly matched by age and sex. Lateral head radiographs were obtained and then cephalometric measurements were compared between the two. Fifty-six measurements were determined to study various skeletal, soft tissue, and airway structure.
Results:
Marked differences were demonstrated in terms of SNB, PG-NB, lower facial height, H-C3Me, and adenoid (A) and tonsil (T/P). The SNB angle (75.82 ± 4.30) in case group was smaller than in the control (78.71 ± 2.61; p = 0.035), the PG/NB value in case group (1.32 ± 0.84 mm) was higher than that in the control (0.62 ± 0.60 mm; p = 0.015). The anterior lower facial height was 65.12 ± 5.91 mm in case group (p = 0.048), while the anterior lower facial height in control was 61.51 ± 3.22 mm. The position of hyoid was lower in case group (5.30 ± 3.67 mm) compared with the control one (2.64 ± 2.58 mm; p = 0.029). Furthermore, the patients with OSA had larger As and T/Ps than the controls.
Conclusions:
The case group differed from the control group in the length of mandible, anterior lower facial height, position of hyoid and the chin, and the size of the As and T/Ps.
