BACKGROUND
Clearing thick secretions from the hidden crevices of the maxillary sinus can be challenging and can increase operative time during endoscopic sinus surgery.
METHODS
We demonstrate the Displacement Technique as a user-friendly technique to address thick secretions within the maxillary sinus barring no orbital floor dehiscence. First, a wide maxillary antrostomy is performed. Then, a surgical pledget is placed in the maxillary sinus to displace the inspissated content into the nasal cavity using a curved suction. This process is repeated as necessary.
CONCLUSION
The displacement technique is a simple and inexpensive method for addressing stubborn secretions.
背景
清除上颌窦隐蔽缝隙中的浓稠分泌物具有一定挑战性，可能会增加内镜鼻窦手术的操作时间。
方法
我们展示了一种移位技术，该技术是一种用户友好型技术，适用于处理上颌窦内无眶底裂开的浓稠分泌物。首先，进行广泛的上颌窦造口术。然后，将一个手术棉片放入上颌窦中，使用弯吸管将浓稠的内容物推到鼻腔中。必要时可重复此过程。
结论
移位技术是一种简单且经济实惠的处理顽固分泌物的方法。
