What Is Passavant's Ridge? We define Passavant's ridge as a "localized soft tissue projection that extends in an arc or crescent along the lateral and posterior nasopharyngeal walls." Passavant's ridge is not a permament pro jection, but rather a "functional" structure, which appears during speech and disappears during quiet breathing (Fig. 9.1).
