Clinical, laboratory and sialographic findings were studied in 35 adul
t patients with recurrent parotitis. The patients were followed up for
0.5-23 years. The results showed that sialographic recovery occurred
3-5 years after disappearance of clinical symptoms. Recurrent parotiti
s is not a autoimmune disease, and remission may take place spontaneou
sly, including clinical and sialographic healing. However, marked dege
neration of the parotid gland or chronic obstructive parotitis may dev
elop consequently. The differential diagnosis of recurrent parotitis i
n adults is also discussed.
