Salivary Mucoceles Tips and tricks
Salivary mucoceles are a collection of saliva that has leaked from a damaged salivary gland or duct and they are surrounded by granulation tissue. They are not cysts. Cysts are cavities lined by epithelium, whereas the granulation tissue lining of a mucocele is produced secondary to inflammation caused by free saliva in the tissues. Saliva takes the path of least resistance, irritates tissue and causes inflammation. Granulation tissue forms in response to the inflammation and prevents saliva from migrating further. The cause of salivary mucoceles is rarely identified. The sublingual salivary gland is the most commonly involved.
