In the present paper we report our clinical experience with hydrostatic sialography, a modification of the conventional technique, which consist in introducing the contrast liquid into the salivary glands by means of gravity pressure. Additionally, a comparative study was done between both techniques. Our results are in accordance with those previously reported in the current literature i.e. the hydrostatic sialography is superior to the current technique, since does not allow the overinjection of the contrast liquid in the salivary gland and also is better tolerated by the patient. However, new experiences with the technique are needed, largely in patients with different diseases of the salivary glands in order to establish the usefulness of the latter in daily practice.
