Abstract: Intro: This study evaluates ultrasound's sensitivity and specificity in detecting conditions like laryngomalacia, valleculae cysts, vocal cord nodules, and paralysis.Objective: To evaluate the diagnostic accuracy of ultrasound(US)in comparison to laryngoscopy for identifying laryngeal disorders in pediatric patients.Methods: A cohort of 36 participants was assessed using both laryngoscopy and ultrasound.Sensitivity, specificity, and inter-rater reliability were analyzed for each condition.Results: Ultrasound demonstrated excellent sensitivity and specificity for laryngomalacia(90％ and 93． 75％, respectively)and valleculae cysts(100％) .For vocal cord nodules, sensitivity was 90％ and specificity 92． 31％, while vocal cord paralysis showed a lower sensitivity of 25％, despite 100％ specificity.The inter-rater agreement yielded a substantial Kappa coefficient of 0． 770, highlighting strong concordance between diagnostic modalities.Discussion: Ultrasound is a reliable, non-invasive tool for diagnosing most laryngeal disorders with high sensitivity and specificity.Conclusion: Ultrasound offers a non-invasive, accurate alternative to laryngoscopy, with potential for further refinement.
