Two-dimensional and Three-dimensional Assessment of the Upper Airway/Evaluacion Bidimensional y Tridimensional de la Via Aerea Superior

The aim of this study was to validate and correlate the two-dimensional (2D) with the three-dimensional (3D) measures of the upper airway assessment. Lateral cephalograms and cone beam CT of 100 adult subjects were used to perform a 2D and 3D assessment of the upper airway. Spearman correlation coef...

Lateral cephalograms and cone beam CT of 100 adult subjects were used to perform a 2D and 3D assessment of the upper airway.

The validity tests of the 2D assessment resulted in a 73 % sensitivity, 45 % specificity, 93 % negative predictive value and 14 % positive predictive value for the nasopharynx; 100 % sensitivity, 51 % specificity, 100 % negative predictive value and 6 % positive predictive value in the oropharynx and 100 % sensitivity, 71 % specificity, 100 % negative predictive value and 13 % positive predictive value in the hypopharynx. There is a weak correlation between the 2D and 3D assessment of the upper airway. However, the lateral cephalogram has a high sensitivity and high negative predictive value, therefore, an additional complementary examination would not be necessary if the 2D assessment of the upper airway throws a normal result.

El objetivo de este estudio fue validar y correlacionar las medidas bidimensionales (2D) con las medidas tridimensionales (3D) de la evaluacion de las vias aereas superiores. Se realizaron cefalogramas laterales y cone beam CT en 100 sujetos adultos para realizar una evaluacion 2D y 3D de la via aerea superior. Se utilizo el coeficiente de correlacion de Spearman para determinar si habia correlacion entre las variables. Ademas, para la evaluacion 2D de la via aerea superior, se calculo la especificidad, sensibilidad, valor predictivo negativo y valor predictivo positivo. Se encontro correlacion en todas las variables entre dos y tres dimensiones. En la nasofaringe y la orofaringe, se encontro una correlacion debil (r <0,51) mientras que en la orofaringe moderada (0,50 <r <0,76). Las pruebas de validez de la evaluacion 2D resultaron en una sensibilidad del 73 %, una especificidad del 45 %, un valor predictivo negativo del 93 % y un valor predictivo positivo del 14 % para la nasofaringe; 100 % de sensibilidad, 51 % de especificidad, 100 % de valor predictivo negativo y 6 % de valor predictivo positivo en la orofaringe y 100 % de sensibilidad, 71 % de especificidad, 100 % de valor predictivo negativo y 13 % de valor predictivo positivo en la hipofaringe. Existe una debil correlacion entre la evaluacion 2D y 3D de la via aerea superior. Sin embargo, el cefalograma lateral tiene una alta sensibilidad y alto valor predictivo negativo, por lo tanto, un examen complementario no seria necesario si la evaluacion 2D de la via aerea superior arroja un resultado normal.
