If a solid nodule in the thyroid gland is very serious, it should be analyzed objectively according to the size of the nodule, whether the nodule causes local compression symptoms, and the nature of the nodule lesion. 1. If the size of the solid nodule in the thyroid gland is relatively small and does not cause tracheoesophageal compression symptoms, and the nodule has no obvious signs of malignancy through ultrasound examination, the patient may be advised to review the thyroid ultrasound in 3-6 months. 2. If the patient’s condition is not serious, the patient can be advised to review the thyroid ultrasound in 3-6 months and no special treatment is needed for the time being. 2. If the solid thyroid nodule is large in size, causing local tracheal, esophageal and nerve compression, the patient has different degrees of swallowing and breathing difficulties, and the ultrasound examination reveals that the nodule has obvious blood flow signal, calcification foci and malignant tumor signs such as aspect ratio greater than 1. In this case, the patient’s condition is more serious, so it is recommended to perform surgery in time to avoid serious complications that may endanger life.
