Thymectomy is a surgical procedure that involves the removal of the thymus gland, which is located in the upper chest behind the sternum. This gland plays a crucial role in the immune system, particularly during childhood, as it helps produce T-cells that fight infections. Thymectomy is often performed to treat conditions like myasthenia gravis, an autoimmune disorder that affects muscle strength. The surgery can be done through traditional open surgery or minimally invasive techniques, such as robotic surgery. Recovery time varies, but many patients can return to normal activities within a few weeks. Thymectomy may improve symptoms and quality of life for those with certain autoimmune diseases.
