The displacement technique: a simple method for clearing maxillary sinus stubborn mucus.

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.
