Sialolithiasis is one of the most common diseases of the salivary
Symptoms are those of recurrent swelling of the affected gland and
pain which is made worse by eating. The problem is typically recurrent.
With ultrasonography, the calculi were correctly diagnosed in 90%
of the patients (6).
Salivary stones were recognized as high-level reverberation echoes
accompanied by posterior acoustic shadows.
Sialoliths predominated among patients aged 30 and 70 years, with
no male/female predilection. 80% of the salivatory stones is found
in the submandibular gland, 15% of them belongs to the parotid and
the sublingual gland comes up with 5%
The submandibular gland is predisposed to stone formation by the
following characteristics: high calcium concentration, dependent
position, small duct opening, high pH saliva, and long curved duct
.A simultaneous stone disease of the urinary tract or the bile duct
system occurred by chance (4%) (1 ; 5).
salivatory stones contain calcium phosphate, 74%; calcium carbonate
11%; soluble salt, 6%; organic elements, 2% and water.
All salivary gland stones greater than 1-2 mm could be detected
ultrasonographically and Mineral composition was found to influence
the radiological study but not sonographic pictures of sialoliths.
If sialolithiasis is suspect clinically, ultrasonography with a
linear scanner must be considered the diagnostic procedure of choice
(2 ; 3 ; 4).
