The nonspecificity of the antral bowing sign in maxillary sinus pathology.
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.
