Lateral right maxillary sinus 8 mm ap x 6 mm transverse x 9 mm craniocaudad mucous retention cyst versus polyp. 

What does that mean?

Depends: If it is asymptomatic and painless then nothing. A usual finding, especially in asthmatics. If there are symptoms, frequent sinusitis, or it is growing as noted on serial exams then removal is recommended with histological examination (biopsy). ...Read more

Can a mucous retention cyst in the left maxillary sinus cause headaches, double vision and selling around the eyes?

Can a mucous retention cyst in the left maxillary sinus cause headaches, double vision and selling around the eyes?

Most would not: A number of mucus retention cysts are often first diagnosed as asymptomatic findings on panoramic radiographs taken in a dental office. If a mucus retention cyst is large enough whereby it occupies enough volume in the maxillary sinus, it could potentially contribute to all of the symptoms you are inquiring about. Further evaluation of your symptoms would be recommended. ...Read more

Chinese medicine can help dissolve them...I suggest you talk to an ENT and a chinese medicine practitioner for more information. ...Read more

I have a mucous retention cyst or polyp in maxillary sinus. Is there any relation to my pituitary tumor or to the fact that I have always had a poor sense of smell?

I have a mucous retention cyst or polyp in maxillary sinus. Is there any relation to my pituitary tumor or to the fact that I have always had a poor sense of smell?

Unrelated entities: A pituitary tumor plays no role in the development/formation of a mucous retention cyst, or a sinus polyp. These are quite common, an usually asymptomatic (unless they block the drainage from the sinus into the hiatus semilunaris or if they are occupying a large volume of the sinus) and i see them as an incidental finding on a weekly basis on radiographs of my patients. ...Read more

I'm experiencing nasal congestion and have a retention cyst in left maxillary sinus. What does that mean?

Common finding : Usually, a mucous retention cyst in one maxillary sinus is of little importance or concern. The cyst is a mucus filled structure on the floor or side walls of the sinus. It can gradually enlarge, but not necessarily. It is unrelated to your nasal congestion. This is something you need to discuss with your otolaryngologist further about long term treatment and follow-up. ...Read more

Can a polyp or retention cyst in the maxillary sinus cause imbalance?

Can a polyp or retention cyst in the maxillary sinus cause imbalance?

Possible but rare: Polyps or cysts in the maxillary sinuses are very common. Unless they are obstructing the opening to the sinus, they are completely benign and nothing should be done, especially surgery. If it blocks the opening, a simple endoscopic surgery can remove the blockage and improve symptoms. ...Read more

Ct results: minor mucosal changes in the paranasal sinuses seen in the maxillary sinus regions with mucous retention cysts. Possible cause?

Not to worry: I see a fair proportion of my patients demonstrating these in their sinuses as an incidental finding on ct scan. They very rarely require any sort of surgical intervention and should be differentiated from a mucocele (which are different. Allergies, sinusitis, mucosal irritation lead to these fluid filled "sacs". ...Read more
