A cephalometric study of children with chronic perennial allergic rhinitis
Insights
Children with chronic perennial allergic rhinitis exhibit distinct craniofacial differences. Their facial patterns are longer and more divergent, with shorter upper jaws, worsening with disease severity.
Area of Science:
- Craniofacial Morphology
- Pediatric Allergy
- Cephalometric Analysis
Background:
- Chronic perennial allergic rhinitis (CPAR) is prevalent in children.
- Potential links between CPAR and craniofacial development are suggested.
- Understanding these links requires detailed cephalometric evaluation.
Purpose of the Study:
- To compare cephalometric features in children with CPAR versus controls.
- To investigate the relationship between CPAR severity and craniofacial morphology.
Main Methods:
- Lateral cephalometric head films were obtained for 100 children with CPAR and 99 controls (ages 6-16).
- Craniofacial morphology was assessed through standardized measurements.
- Statistical analysis was performed on the collected data.
Main Results:
- Children with CPAR showed significantly longer and more divergent facial patterns compared to controls.
- A shorter maxilla (upper jaw) was observed in children with CPAR.
- Increased vertical facial dimensions and hyperdivergence correlated with CPAR severity.
Conclusions:
- CPAR is associated with specific craniofacial alterations in children.
- Facial hyperdivergence and maxillary shortening are key cephalometric findings in pediatric CPAR.
- The severity of CPAR influences the expression of these craniofacial characteristics.
Abstract:
This study compared the cephalometric features of a group of one hundred children aged from six to sixteen years suffering from chronic perennial allergic rhinitis of differing grades of severity with those of 99 control subjects of similar age. Both samples were drawn from a Children's Hospital which has a large population of patients with chronic perennial allergic rhinitis attending the Allergy Clinic. Lateral cephalometric head films of each subject were recorded and a series of measurements made to assess and compare the craniofacial morphology. The data were statistically analysed. The study found that the children suffering from chronic perennial allergic rhinitis had longer and more divergent facial patterns as well as horizontally shorter maxillae than those in the control group. In addition, those parameters associated with increased vertical dimension and hyperdivergence demonstrated progressive expression with increasing severity of the chronic perennial allergic rhinitis.
