"In May 2017, a clearly visible thyroid nodule measuring about four centimeters was discovered on the left side of my thyroid gland and a smaller nodule and a cyst filled with fluid on the right side. However, a blood sample showed that I did not suffer from either hypothyroidism or hyperfunction of the thyroid gland. The endocrinologist I consulted advised me to have the entire thyroid gland removed. And to do so before the nodules were examined for potential malignancy. Since I am a single mother of two small children, this diagnosis posed a big problem for me, as the removal of the thyroid gland is associated with risks such as loss of voice as well as the lifelong intake of hormones, which have to be continually adjusted and, above all, requires an initial hospital stay of several weeks. I looked into the findings and found out that there is a newer treatment method of thermal ablation aimed at destroying the nodules by heating. Prof. Dudeck is the first doctor in Switzerland to perform this treatment in Hirslanden in Zurich. Prof. Dudeck reacted very quickly after I contacted him and analyzed the nodules for thermal ablation feasibility as well as whether the nodules were malignant. I received his positive diagnosis within a very short time. He then performed the thermal ablation sometime later. It lasted only a short time and did not cause any pain. He and his team took fantastic care of me. I felt very well again immediately after the surgery and had no side or late effects. I was able to go back home to my children the next day. The ablated large nodule is hardly visible anymore, the small nodule has completely disappeared. The follow-up examination with Prof. Dudeck showed that the larger nodule will shrink further. I assume that it won't be visible much longer. My thyroid functions normally.

I am amazed by the results of Prof. Dudeck. Without him, I would have lost my actually functioning thyroid gland along with its potential risks and lifelong medication. Instead, I'm fine and my health is completely restored. I am incredibly happy and grateful for the help I have received from Prof. Dudeck."

"We (my husband and I) are thrilled. The difference can already be felt inside and out. It's just wonderful. Thank you for your work."

"I accidentally became aware of thermal ablation and even today (3 months after the surgery) I am very glad that I have chosen this method. I was awake during the procedure, was able to hear everything and after the successful surgery, I was able to admire the result right away via ultrasound. Today, as I said 3 months after the operation, about 70% of the nodule has disappeared and I have no "consequential damages".

I will recommend this method to anyone in a similar situation."

""It was a wonderful experience for me to see after the ultrasound how enormously my large nodule has already shrunk in this short time.

I am very happy that I have had this method, that you offer, performed by you. Thank you very much. I am very grateful that I have accidentally read about this method in a medical journal.

Before this surgery, I had no energy, could not sleep well and had strong bronchitis every year and was often in a bad psychological condition. Since I'm in a choir, I was worried that I wouldn't be able to sing anymore, because I very often had a strong tension on the right side of my neck, which has now disappeared.

Immediately after the surgery, I was feeling psychologically very well, all negative impressions that came from outside bounced off me. This has continued to this day, with a few small exceptions. My sleep has improved a lot, I have energy again that sometimes I feel like I could run a marathon. I didn't get a cold or even bronchitis this year, even though my husband has been dealing with it for weeks.

I believe that this too was due to this therapy. I very much hope that this procedure will receive more attention from doctors and especially family practitioners. This procedure is not painful and I was very well cared for during my stay at the clinic.

I hope that you will be able to help many more people with this gentle method."

"After I found Prof. Dudeck as a specialist for "treating thyroid nodules without a scalpel" on my own initiative and in responsibility to my body/health and after we made a quick appointment, I had for the first time the feeling that someone can help me. The explanation of thermal ablation was quite extensive and meaningful to me that I agreed to the small surgery. A surgery without scars, without general anesthesia and without lifelong dependency on medication.

Today, after 3 months I am more than happy and satisfied with my thyroid gland. Meanwhile, I can wear a scarf, a turtleneck, even a necklace. I have no shortness of breath, no more difficulty swallowing or the feeling that someone is choking me. I don't need to take any medication, I don't have any scars and thanks to the thermal ablation I had done, I am doing extremely well after years of fighting for the preservation of my thyroid gland.

I have a quality of life again, a healthy quality of life."

"Thanks to thermal ablation, I was able to keep my thyroid fully functional.

Due to a disturbing goiter on my right thyroid lobe that had almost grown to the size of a kiwi and smaller nodules on the left side,  I had already scheduled an appointment for thyroid removal. Fortunately, I read an article in the "Schweizer Illustrierte" just in time about the thermal ablation method of benign thyroid nodules in the Hirslanden Hospital of Prof. O. Dudeck. I immediately contacted him by mail and received an answer from him personally the very next day. After it became clear in the course of the examinations that the nodules were benign, Prof. O. Dudeck's thermal ablation could take place under local anesthesia (duration approx. 30 minutes). I was able to speak during the surgery and felt no pain at all. Immediately after the surgery, the kiwi-sized nodule had shrunk to chestnut size. Today, 6 months later, I can still feel the knot twice the size of a pea. But nobody's staring at my neck anymore because of the goiter. I am glad and grateful to have decided for this "mini-intervention" in the best atmosphere with Prof. O. Dudeck. My thyroid is fully functional today. If the thyroid gland had been almost completely removed, I would now have to take thyroxine and possibly even calcium for the rest of my life. I can only recommend the procedure to any fellow sufferer with benign thyroid nodules."
