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.
