Sphenochoanal polyp is a rare form of choanal polyp. If unrecognised, they can be mistaken for an antrochoanal polyp. This will result in unnecessary exploration of the maxillary sinus, and a failure to remove the sphenoidal component of the sphenochoanal polyp. Adequate preoperative evaluation with computed tomography or magnetic resonance is mandatory to ascertain the correct diagnosis, and to facilitate the planning of the appropriate surgical procedure. We present two patients with sphenochoanal polyp and a review of the literature.
蝶筛后鼻孔息肉是后鼻孔息肉的一种罕见类型。如果未被识别，它们可能会被误诊为上颌窦后鼻孔息肉。这将导致对上颌窦进行不必要的探查，并且无法切除蝶筛后鼻孔息肉的蝶窦部分。术前必须进行计算机断层扫描或磁共振成像等充分评估，以确定正确诊断，并便于规划适当的手术程序。我们报告了两名患有蝶筛后鼻孔息肉的患者，并对相关文献进行了综述。
