What treatment is available for thyroid cysts?
Thyroid cysts account for approximately 10% of all thyroid nodules. Draining the cysts is usually a temporary treatment because the cysts rapidly refill with fluid. Permanent treatment required removing half the thyroid gland. Recently it was discovered that injecting alcohol (100% ethanol) after removing the fluid would eliminate the cyst. This treatment (percutaneous ethanol injection) has now replaced surgery as the treatment of choice for cystic nodules in many thyroid clinics.
