Experiments involving thymectomy in newborn mice showed that it unexpectedly resulted in wasting disease when performed before the mouse was three days old. This is because the thymus is the site where T cells are generated. Removal of the thymus resulted in autoimmunity, in which the immune cells attack the organism's own healthy cells and ...
Thymectomy is the surgical removal of the thymus. [2] The usual reason for removal is to gain access to the heart for surgery to correct congenital heart defects in the neonatal period. [27] Other indications for thymectomy include the removal of thymomas and the treatment of myasthenia gravis. [2]

Subtotal thyroidectomy — Removal of majority of both lobes leaving behind 4-5 grams (equivalent to the size of a normal thyroid gland) of thyroid tissue on one or both sides—this used to be the most common operation for ...

Tonsillectomy is the removal of the tonsils. Trabeculectomy is the removal of part of the eye's trabecular meshwork as a treatment for glaucoma.
Such trials have been performed with kidney and heart transplants, drastically extending the time the animals were surviving without immunosuppressing drugs. [5] The first human heart-and-thymus co-transplantation was performed on Easton Sinnamon in 2022, a newborn who suffered from both a lack of T cells, and a serious heart defect.
[6] [9] Surgical removal of the mass is the definitive treatment for ectopic thymus tissue that is causing symptoms. [4] It has been reported that the ectopic thymus tissue can transform into cancerous tissue. [4] However, due to most diagnosed ectopic thymus tissue being resected due to this concern, the natural progression is not well explored.
Surgical removal (excision or debridement) of the damaged skin is followed by skin grafting. The grafting serves two purposes: it can reduce the course of treatment needed (and time in the hospital), and it can improve the function and appearance of the area of the body which receives the skin graft.
