Thyroid Biopsy

What is thyroid fine needle biopsy?

Thyroid biopsy is performed in patients with goitre by a thin needle. In goiter patients, sometimes the gland grows completely, and sometimes the nodules develop in the thyroid gland. Thyroid nodules are more common in women than men. Most of these nodules are benign. It is generally understood by the ultrasound performed by an experienced radiologist that the thyroid nodules are good or malignant. Such nodules do not require a biopsy. Occasionally, ultrasound views may be suspicious, suggesting a malignant tumor. In such cases, a definitive diagnosis can be made with fine needle aspiration biopsy.

When is the biopsy applied?

If the image of the nodule in the choroidal gland detected during thyroid ultrasound suggests a similar appearance to the growth in the lymph nodes around the thyroid gland and the image in the nodule, then a thyroid biopsy should be performed if a specific type of goiter is present and a accompanying nodule is observed. In patients with multiple nodules, which biopsy is performed from which nodule is determined by ultrasound. A thorough laboratory examination should be performed prior to the biopsy for a good physical examination and other thyroid diseases.

Is thyroid biopsy a safe method?

Thyroid needle biopsy is almost always performed with very fine needles called dental, because it is very safe and simple. Biopsy is often frightening, but simple. Thyroid biopsy is the easiest and least risky biopsy.

Is preparation necessary before thyroid biopsy?

Since the thyroid biopsy is performed with very fine needles, there is no need for any preparation. It can be done at any moment.

Is the procedure painful?

It is not very painful because it is done with very ine needles and not entered into deep tissues. Nevertheless, local anesthesia is performed before the procedure.

How is it applied?

The patient's thyroid gland is re-examined with ultrasound. Input location is determined. The support pillow is placed under the neck to allow the head to fall backwards, thus making the biopsy process more comfortable. After the region is prepared as sterile, the area to be biopsied is anesthetized by a fine needle and anesthetized. Then aspirate with an even thin needle. Thus, liquid or cell samples are taken from the nodule. This is a painless procedure. Multiple input may be required if the bad looking nodule is more than one. Each time, the entrance is drugged.

Is there any error in the diagnosis?

The biopsy of the thyroid nodules is done with a very thin needle. Security is very good, almost no risk. However, a piece of tissue was not taken, only cells were drawn with the needle. Therefore, there may not always be definitive diagnosis.

What are the complications?

With the correct approach and a good technique, usually the complication does not occur. However, infection, bleeding and cyst formation may be rare.

What should we do after a biopsy?

Biopsies with fine needle are very safe methods. Therefore, there are no limitations after the biopsy. The patient can get up immediately, take a bath, return to normal life. In rare cases, there may be pain where the needle enters, so patients can use painkillers after the procedure.
