How is thyroid nodule puncture done?

Thyroid nodule puncture is a common method used to determine the nature of thyroid nodule in clinical practice. The specific procedures are as follows: 1. The specific location of thyroid nodule is determined by ultrasound examination. 2. After the puncture site was determined, local infiltration anesthesia was performed at the puncture site with 1% lidocaine injection. 3. After satisfactory local anesthesia, a 0.5cm incision was made at the puncture point, and the specific location of the thyroid nodule was revealed by the color ultrasound probe. The puncture needle was held in the right hand and slowly inserted through the skin incision, gradually passed through the subcutaneous tissue and platysma muscle into the thyroid gland and reached the nodule. 4. Repeatedly puncture the inside of the thyroid nodule and send the specimen to smear cytology. If the smear specimen of the thyroid nodule is not satisfied, puncture and take the sample as many times as possible to avoid the specific nature of the nodule.
