Mucocele/Adenitis of the Zygomatic Gland
Description of the Disease and Clinical Picture
Mucocele of the zygomatic gland occurs due to damage to the gland or its duct, leading to the accumulation of saliva within a cystic formation. The process is usually unilateral, chronic in nature, and most often not painful. In the patient, exophthalmos can be observed along with protrusion of the third eyelid.
Adenitis of the zygomatic gland (sialoadenitis) is an acute process, painful, and does not result in the formation of a cyst within the gland. Often, a larger number of secretory glands are affected. The process is most often of an autoimmune nature.
 
Therapy
The diagnosis is made by ultrasound examination, CT, or MRI scans. Three to four weeks of therapy with nonsteroidal anti-inflammatory drugs can lead to the reduction of swelling and resolve the problem. Surgical resection of the cyst is also an option. Polidocanol can be injected into the cyst to induce its regression, but sometimes it can cause a strong inflammatory reaction.
