title: The nonspecificity of the antral bowing sign in maxillary sinus pathology.
abstract: Although bowing of the posterior antral wall occurs most commonly with juvenile angiofibroma, it can occur with any slow growing noninvasive lesion involving the retromaxillary region. Cases of schwannomas, a lymphoepithelioma, and a fibrous histiocytoma are presented as examples of the nonspecificity of the antral bowing sign.
