Cingulotomy aims to injure the anterior cortex of the cingulate gyrus in order to promote cognitive-emotional changes in the patient's perception of their pain. Postoperative follow-up was performed on 14 patients who underwent bilateral stereotactic cingulotomy to relieve chronic non-cancer pain associated with medically intractable depression. Of the 14 patients selected, 5 men and 9 women, 4 suffered from craniofacial pain, 7 from chronic tension headache, 2 from fibromyalgia and one from chronic pelvic pain. Patients were evaluated according to the Hamilton scale for depression (0-62 points), the visual analogue scale for pain (VAS: 0-10 points) and the number of hospitalizations. Before the operation, the average VAS score was 9.28 and the Hamilton score was 31 points. In the first year, the results showed a significant improvement and reached an average of 4.22 points on the VAS and 18 on the Hamilton scale. In the second year, the average score according to the VAS was 4 points and according to Hamilton, 16.3. In the third year the average value was 5.3 on the EVA and 19.3 points on the Hamilton scale. At the fourth year of follow-up, it was shown that the improvement was sustained, with an average of 3.3 points on the VAS and 16.3 on the Hamilton. The number of hospitalizations in the first year decreased by 83.7%; during the second and third years, 88.6%, and it reached 100% in the fourth. The results show the role of cingulotomy in relieving pain and suffering in well-selected patients.
