以往对于鼻窦、上颌窦检查时 ,大都采用俯卧式瓦氏位摄片检查 ,将患者俯卧在摄影台上 ,Ｘ线垂直拍照。这种方法较为传统 ,摆放时操作人员和病人都不方便 ,因此 ,照片上经常出现鼻窦或上颌窦显示不很清楚 ,影响诊断结果。经过反复实践我们改用立位后 ,效果良好 ,且摆放位置方便 In the past for sinus, maxillary sinus examination, most of the use of prone Valsalvae radiography, the patient prone on the photography stage, X-ray vertical photo.

After repeated practice we switched to standing position, the effect is good and the location is convenient
