Abstract
Stridor occurs when a portion of the upper respiratory tract (larynx, oropharynx, nasopharynx, or oral cavity) is obstructed. The location of the lesion is indicated by the character of the stridor; if at or above the level of the vocal folds, it is inspiratory and, if caused by a lesion just below the vocal folds (subglottis), is both inspiratory and expiratory and is therefore called biphasic stridor. Lesions of the trachea, larger bronchi and secondary bronchi, cause expiratory stridor. Obstruction distal to the larger secondary bronchi is usually characterized by expiratory wheezing.
