A statistical analysis with the chi-square test was unable to show a difference between the above procedures, regarding the definitive resolution of the disease. From the 55 cases, 9 (16.6%) had total remission, 41 (74.5%) remained with symptoms and need some kind of treatment, and 5 (9.09%) died (three patients with thymoma, one patient with congenital myasthenia gravis, severe kyphoscoliosis and pulmonary restriction, and one patient during the thymectomy procedure). It was found a relation between the signs of respiratory insufficiency, myasthenic crisis and thymoma only in the group of patients who died.
