Abstract:
Objective:To analyze the characteristics of upper airway three-dimensional CT images in children with laryngoscope exposure.Methods:50 cases of Pierre Robin sequence who suffered mandibular distraction osteogenesis were included. Preoperation, Cone beam CT scan was performed to get upper airway anatomy information. Images were imported into medical engineering software Mimics for 3D reconstruction. The related anatomical parameters such as the cross-sectional area of the epiglottis tip, oral volume, palatopharynx volume, and glossopharyngeal volume were measured. The exposure of glottis was observed by direct laryngoscope after anaesthesia. According to Cormack-Lehane classification, 2 groups were divided into groups (group A, 30 cases), non exposure group (group B, 20 cases), and the difference of image data between the two groups was compared.Results:Comparing CT measurement index values of the two groups, it was found that there were no statistically significant differences in D4, D8, D10, D11, angle 3, angle 6 and oral volume between the two groups ( P≥0.05), while there were statistically significant differences in other indicators between the two groups ( P<0.05). The area of the airway at the tip of epiglottis and the volume of palatopharyngeal cavity are of great significance to the differential diagnosis of laryngoscopic exposure in children with Pierre Robin sequence, and the decision tree model was established accordingly. Conclusions:The decision tree model based on the area of the airway at the tip of epiglottis and the volume of the palatopharyngeal cavity can predict the difficulty of laryngoscopic exposure in children with Pierre Robin sequence.
