What does evidence of bilateral medial any rectories and partial ethmoidectomiies mean in relation to sinuses without air fluid levels mean?

Sinus surgery: It looks like some of your terminology is a little off, but partial ethmoidectomies means that the ethmoid sinuses have been partially opened surgically. Other common findings when someone has had sinus surgery are maxillary antrostomies, sphenoidotomies and frontal sinusotomies. Sometimes, turbinate work is done and this could be called a turbinectomy. No fluid usually means no infection

It sounds like you: have a copy of your sinus CT scan report! I'd be a little surprised if you had had bilateral medial antrectomies, or removal of a portion (the antrum) of the walls of the maxilla. Usually an antrostomy is done--making an opening into the maxillary sinus--along with the ethmoidectomy. After this surgery, done to promote drainage, one would not expect to see fluid blockage/air fluid level.
