Diagnostic Test Value of Assessment Adenoid Enlargement with and Without Airway Obstruction Using Lateral Soft Tissues X-ray Compared to Nasoendoscopy

Abstract

Adenoid hypertrophy is one of the most important causes of airway obstruction. Skull lateral soft tissues X ray are reliable diagnostic tools for detection adenoid enlargement with or without airway obstruction. Compared to nasoendoscopy that invasive and not available in all hospital. The aim of this study is to evaluate the diagnostic value of Skull lateral soft tissues X ray for assessment adenoid enlargement using Kurien, Cohen and Konak, Fujioka and McNamara methods compared with nasoendoscopy. Analytic observational with cross sectional study. 24 patients suspected adenoid enlargement was performed Skull lateral soft tissues X ray and measured the enlargement with Kurien, Cohen and Konak, Fujioka and McNamara methods. After performed X-ray these patients was been nasoendoscopy. Diagnostic value of Skull lateral soft tissues X ray Kurien methods show sensitivity was 73.6%, specificity 100%, positive predictive value 100%, negative predictive value 50% and accuracy 79.1%. Diagnostic value of Skull lateral soft tissues X ray Cohen and Konak methods show sensitivity was 94.7%, specificity 100%, positive predictive value 100%, negative predictive value 83.3% and accuracy 95.8%. Diagnostic value of Skull lateral soft tissues X ray Fujioka methods show sensitivity was 10.5%, specificity 100%, positive predictive value 100%, negative predictive value 22.7% and accuracy 29.1%. Diagnostic value of Skull lateral soft tissues X ray McNamara methods show sensitivity was 68.4%, specificity 100%, positive predictive value 100%, negative predictive value 45.4% and accuracy 75%. Adenoid enlargement can be measure with Skull lateral soft tissues X ray using Cohen and Konak method that has the highest sensitivity, specificity, and accuration compare another methods and using McNamara methods can predict the airway obstruction.
