Inflammatory polyps that arise in the maxillary antra may extend into the nasal cavity and result in nasal obstruction. In some instances a combination of roentgenographic findings is helpful in diagnosis. This combination includes diminished aeration of the involved maxillary antrum, expansion of the antrum, and a soft tissue mass within but not arising from the nasopharynx.
发生于上颌窦的炎性息肉可延伸至鼻腔并导致鼻塞。在某些情况下，X线检查结果的综合表现有助于诊断。这些表现包括患侧上颌窦的通气减少、窦腔扩大以及鼻咽部内的软组织肿块（并非起源于鼻咽部）。
