Abstract :
The occurrence of salivary stones in the parotid gland 
is rare. In this paper, four cases of salivary stones 
found in the parotid gland are reported and the 
clinical and radiographic features were discussed. The 
patients consisted of one male and three females in 24 
to 64 years of age. They were associated with 
parotitis and swelling of the cheek or buccal mucosa, 
but the symptoms were mild. All stones were found in 
the duct and relatively small in size, but two stones 
were present in three patients. Ultrasonography and CT 
were quite useful in diagnosing the location and 
number of stones. With the exception of a case in 
which the stones were discharged spontaneously in 
association with pus discharge, the stones were 
surgically removed by an intraoral approach in all 
cases.
