The maxillary sinus, like other paranasal sinuses, secretes mucus. If this mucus does not flow out, and is blocked in the lining of the sinus, a cyst is formed. The cyst is filled with the "retained" secretions. This is called ‘maxillary sinus mucus retention cyst’.
This is found in cases of chronic sinusitis. If the cyst is small, you may not need to remove it. Please consult an ENT surgeon for treatment options. A cyst is surgically removed if it is obstructing the natural sinus drainage and in case it is very large, or secondarily infected.

I have mucus retention cysts in both maxillary sinuses too. The problem for me is this insane post nasal drip for already 2 years or more now. Sometimes it´s so difficult to swallow the mucus my neck is sore. I also have sleep apnea. Can these be indications for surgery? I don´t know how big the cysts are, the CT scan wouldn´t say. Thanks.
