Abstract Objective: To explore the structural features of upper airway morphological in snoring children with multislice spiral CT scan and post-processing techniques and to reveal the relationship between structural abnormalities and the severity of snoring. Methods: Children with snoring were enrolled and divided into primary snorer (PS) group (n=45) and obstructive sleep apnea hypopnea syndrome (OSAHS) group (n=73) based on polysomnography (PSG). Another 40 cases were enrolled as the control group (n=40). Multislice spiral CT scan covering upper airway was performed and measurements of soft tissue, bone structure and spatial structure of the upper airway were obtained from a 3-dimensional segmentation using image analysis workstation of phillips Corp. Results: The area, length, thickness and volume of adenoid, the area and the volume of the soft palate, the cross-sectional area of the tonsils in snoring children groups were significantly higher than those in the control group (P<0.05). The cross-sectional area of the the velopharyngeal, the anterroposterior diameter of the velopharyngeal, the nasopharynx volumes and the velopharyngeal volumes, the paranasal sinus volumes in snoring children groups were significantly reduced than that in the control group (P<0.05). The angle (α) was smaller and adenoid-nasopharynx ratio increased in snoring children groups than those in the control group (P<0.01). Conclusion: The snoring children have airway obstruction of various degrees at the upper airway because of the adenoid and tonsillar hypertrophy and the enlarged soft palate. Sinusitis is often complicatd and lower hyoid bone position moves down leading to increased upper airway resistance.
