The choice of fine needle puncture for thyroid disorders also has certain hazards. Complications can easily occur during surgical puncture, commonly in patients with malignant tumors, which can easily lead to implantation and metastasis of tumor cells, which is also a serious complication. Some patients are prone to side injuries during the puncture process. Commonly, glandular injury can lead to bleeding, and vascular injury can easily lead to secondary bleeding. Patients with nerve injury may experience pain, numbness, and even abnormal pronunciation. It is best to be guided by color ultrasound during the puncture process to significantly reduce the chance of complications. Some patients are prone to local inflammatory reactions after puncture, i.e., infections, which can be treated with oral anti-inflammatory drugs. However, in general thyroid puncture is necessary to clarify the nature of thyroid nodules and the overall risk is low for experienced physicians.
