上颌窦出血性息肉的 X 线诊断

X-ray Diagnosis of the Bleeding polyp in Maxillary Sinus

出血性息肉为鼻窦炎性息肉的一种类型。本文报告68例,几乎都为单侧,好发于上颌窦,以中青年为常见。X 线检查大多可见窦腔扩大伴有骨质吸收破坏,结合鼻内有坏死样息肉。鼻出血和颌面肿胀等表现,在术前多可提出诊断。本文着重介绍华、柯氏位鼻窦平片综合观察的体会,强调柯氏位对观察上颌窦顶和内上壁的优点。

The bleeding polyp is a form ofimflammatous polyps of the nasal sinuses,most commonly involving uni-lateral maxillary sinus.The clinicaland radiologic findings are often si-milar to that of benign and malignanttumors.The authors retrospectivelystuded the sinus radiographs of 68patients with bleeding polyp.We re-vealed antral bowing with bone ero-sion in vast majority cases.Combi-ning with existence of nasal polypand epistaxis,we can make a correctdiagnosis preoperatively.Both Wate-r's and Caldwell's positions are im-portant,but the Caldwell's view isbetter in showing the antral roof andmedial wall.
