There is one cavea on either side of the nose, which is called "maxillary sinus".

在鼻腔两侧各有1个空腔,称为"窦"。

The uncinate fragment is then grasped and removed as one piece.This should bring into view the opening of the maxillary sinus and facilitate subsequent maxillary sinus meatotomy.

这时可以看窦开口，为进一步窦口扩大术提供便利。

ObjectiveTo discuss the CT manifestation and clinical significance of rare neoplasm in maxillary sinus, includingmalignant myoepithelioma, angioendothelioma, sarcoma of plasmacyte.

目探讨窦恶性肌皮瘤、血管内皮瘤及浆细胞肉瘤CT表现及临床意义。
