Thymectomy is a surgical procedure to remove the thymus gland and may be recommended for patients with thymic tumors, including thymoma, or individuals with myasthenia gravis. Depending on the patient's condition, the procedure may be performed through open surgery or minimally invasive approaches such as video-assisted or robotic-assisted surgery. Before treatment, doctors typically perform imaging and other assessments to evaluate the thymus and surrounding structures. Postoperative monitoring and follow-up help support recovery.
