ABSTRACT
Objetivo: La permeabilidad nasal se correlaciona con unos parámetros funcionales y anatómicos, que se objetivan mediante la rinomanometría anterior activa (RNMAA). Objetivo: Se pretende comparar las alteraciones visualizadas mediante endoscopia nasal (EN) con los parámetros de la RNMAA. Material y métodos: Se realiza un estudio observacional prospectivo de 45 pacientes afectos de obstrucción nasal y desviación septal. Se exploran mediante RNMAA y EN, clasificando las desviaciones en cuadrantes anterosuperior y anteroinferior. Se analiza el grado de concordancia interobservador y la validez de la prueba diagnóstica. Resultados: Se obtiene una sensibilidad y especificidad del 74,6% y 60,5% respectivamente, comparando globalmente la RNMAA con la EN. Conclusión: La disminución del flujo en fase espiratoria se correlaciona con las obstrucciones inferiores objetivadas en la EN. En el estrecho vestíbulo fosal, esta correlación no es predictiva (AU)
Objective: Nasal permeability is related to functional and anatomical parameters, which are objectified by active anterior rhinomanometry (AARNM). The study aims to compare alterations visualized through Nasal Endoscopy (NE) with nasal flow parameters in AARNM. Material and methods: We carried out a prospective observational study of 45 patients suffering from nasal obstruction and septal deviation. They were explored through AARNM and NE, and the deviations were classified into anterosuperior and anteroinferior quadrants. The degree of agreement between observers and the validity of the diagnostic test was then analyzed. Results: A sensitivity of 74.6% and a specificity of 60.5% were obtained comparing AARNM and EN globally. Conclusion: A reduced flow of the expiratory phase is correlated to inferior obstructions observed through NE. In the narrow nasal vestibule this correlation is not predictive (AU)
