The lateral neck radiograph in adenotonsillar hyperplasia

In this study we have considered whether the lateral neck radiograph is useful in predicting the degree of airway obstruction, and whether supine and erect views are more useful than a single film. We evaluated the supine and erect lateral neck radiographs of 50 patients with upper airway obstruction due to enlarged tonsils and adenoids. Our results show that the supine radiograph, which is technically easier to perform, is entirely satisfactory for appraising the size of the tonsils and adenoids, but that neither view tells us much about the degree of airway obstruction during sleep.
