    Abstract:
    Since 1967, transcervical thymectomy has been the procedure of choice for all patients with nonthymomatous myasthenia gravis and a selected group of patients with thymomatous myasthenia gravis operated upon at the Mount Sinai Hospital. A total of 180 transcervical thymectomies have been performed. In 12 patients, a pre-existing tracheostomy was present. Morbidity was minimal, limited to three instances of bleeding, five of pneumothorax, one of self-limited chylothorax, and one wound infection. One postoperative death from an unrelated cause occurred in 1967. The postoperative course has been smoother and the management of the myasthenia gravis considerably easier than those following transthoracic approaches. Consequently, routine elective tracheostomy at the time of thymectomy has been abandoned. The average period of hospitalization does not exceed one week. As a result of the minimal risk involved, indications for thymectomy now include all patients with generalized myasthenia gravis, and the procedure is performed earlier in the course of disease. Postoperative electromyographic findings show immediate improvement in the majority of patients operated upon during the first year in which symptoms occur. Transcervical thymectomy arrests the progress of the disease, decreases the mortality rate, and has long term results equal to those of transthoracic approaches. Earlier remissions, fewer germinal centers, and a smaller number of thymomas were noted in patients operated upon early in the course of the disease. A decrease in neoplasms outside the thymus gland and in neonatal myasthenia gravis was also noted following thymectomy.
