Fifty-six board-certified neurologists with interest and expertise in myasthenia completed a survey of indications for thymectomy in myasthenia gravis. Thymectomy was advocated for virtually all patients with thymoma, for a variable subset of patients with generalized myasthenia without thymoma, and occasionally for selected patients with disabling ocular myasthenia.
