Résumé
To analyze the judgment efficiency of a computer stress model and severity score in severity evaluation and treatment plan selection of laryngomalacia patients. Twenty-two children (12 cases in the operation group and 10 cases in the follow-up group) with moderate to severe laryngomalacia were assessed by laryngomalacia severity score (LSS) which included visual analogue scale (VAS) and clinical score. A computer stress model of the laryngeal cavity was constructed for all children, with the von Mises stress peak (VMSP) of the model used as another quantitative evaluation method. The ROC curves of two quantitative evaluation methods, the LSS and the VMSP, were analyzed respectively, according to the clinical guideline which is regarded as the gold standard for judging whether surgery is needed. The diagnostic efficiency indexes such as sensitivity, specificity, and accuracy were calculated. The area under ROC curves (AUC) of the two methods were compared by a DeLong model. Spearman correlation analysis and Kappa test were used to test the correlation and consistency of the two quantitative evaluation methods. The independent sample t test was used to compare the difference of LSS and VMSP between operation group and follow-up group. The sensitivity, specificity, and accuracy of LSS in judging whether laryngomalacia was operated or not were 83.33%, 80.00% and 81.82%, respectively, and the area under ROC curve (AUC) was 0.825 (p < 0.05). The sensitivity, specificity, and accuracy of the computer stress model for laryngomalacia were 58.33%, 90.00% and 72.73%, respectively, and the AUC was 0.796 (p < 0.05). The spearman correlation coefficient between LSS and VMSP was 0.833, p < 0.001, which is statistically significant. LSS (t = 3.251, p = 0.004) and VMSP (t = 2.435, p = 0.024) of the two groups were statistically different. VMSP and LSS have high diagnostic efficacy in the quantitative evaluation of the severity of laryngomalacia and the selection of treatment plan. The consistency of the two quantitative evaluation methods is good, which has practical value for the evaluation of the severity of laryngomalacia and has guiding significance for surgery.
