Treatment of thyroid cysts generally does not require special treatment, just regular monitoring of thyroid ultrasound and thyroid function. Thyroid function must be monitored for thyroid cysts. When thyroid function is reduced, hormone replacement therapy is needed. When thyroid function is hyperactive, anti-thyroid treatment is needed. If the patient's thyroid function is normal, only regular monitoring of thyroid ultrasound and thyroid function is required to understand changes in the size of the cyst. However, if the cyst is large enough to cause symptoms such as breathing difficulties or carotid ischemia, surgical treatment is recommended in a timely manner. Currently, radiofrequency treatment is also a new treatment method, which can be considered as an alternative option, but it is not recommended.
