To determine the frequency of complications and the usefulness of this technique.
Patients who underwent a minor salivary gland biopsy for a possible diagnosis of SS at Rivadavia Hospital between October 2007 and May 2010 where included. The patients were seen a week and a month after the procedure for follow-up.
Frequency of acute complications (n=186): 15 patients; 8.1 % , 95 % CI: 4.7-13.2 (Bleeding 7.5 % , syncope 3.2 % , hematoma 2.7 % . No accidents occurred). Medium term complications (n=164): 16 patients: 9.75 % , 95 % CI: 5.9-15.6 (pain 7.32 % , inflammation 3.66 % , sensitivity disorders 3.05 % , granuloma 1.22 % ). No infections or suture dehiscence occurred. Microscopic results: 154 biopsy reports were received: glandular 90.9 % , 95 % CI: 85-95 (typical, sialadenitis, grade III and IV infiltration).
MSGB has very low frequency of medium term and acute complications and it has high usefulness.
