Thyroid and Parathyroid Disease

Dr. Wreesmann is a thyroid and parathyroid surgeon with more than 10 years experience.

He was fellowship-trained at Memorial Sloan Kettering Cancer Center in New York, a leading center for treatment of thyroid and parathyroid tumors. Dr. Wreesmann has performed more than 500 thyroid and parathyroid operations among patients across all age groups, including patients who have undergone failed initial surgery for (para)thyroid cancer elsewhere, or have recurrent (para)thyroid cancer. 

Our team works in close collaboration with specialized endocrinologists to provide integrated care for all thyroid and parathyroid conditions. This includes thyroid nodules, goiters, (para)thyroid adenomas, thyroid cancer, and all types of thyroid and parathyroid (revision) surgery. We offer a coordinated service suited to all aspects of thyroid and parathyroid disease. Correcting (para)thyroid problems requires an integrative approach, including nutritional support and lifestyle changes. This is why our team works with a variety of disciplines such as nutritionists, dieticians, physiotherapists, and family practitioners.

Whatever the problem regarding your thyroid or parathyroid, we will help you find the solution. 


During your consultation for a (para)thyroid problem, examination may include one or more of the following:

Palpation of (feeling) the thyroid- we will feel your neck and assess your thyroid for size, aspect, and consistency, amongst others. We will assess the rest of your neck, including your lymph nodes and salivary glands. The parathyroid cannot normally be felt with the hands. 

Flexible endoscopy-in some cases of thyroid disease, it is necessary to assess your voice box and the mobility of your vocal cords through a flexible endoscopy. This involves inserting a small camera into your nasal cavity.  The endoscope we use is a thin, flexible tube with a tiny, built-in camera at the tip of it. During the examination you will be asked to make certain sounds, which helps us assess your vocal cords better. Flexible endoscopy is done awake, but at your request a local anesthetic (numbing) spray can be used. 

Blood tests- you may be referred for blood tests at one of our other clinics. Tests may include thyroid hormone levels, parathyroid hormone levels and calcium, amongst others. 

Ultrasound of the thyroid- a specialized radiologist will carry out an ultrasound of your thyroid. They will put some gel over your skin and pass a probe over the thyroid area, which will be visible on a monitor. 

Fine needle aspiration or needle biopsy-in some cases, during the ultrasound, the radiologist may insert a thin needle into your thyroid and aspirate a sample of cells or a small biopsy out for further investigation. A pathologist (a doctor who studies bodily tissues and fluids) will study the cells or tissue fragments under a microscope. This takes some time, and you will be given your results around two weeks after the investigation.

Sestamibi scan-you may be referred for a  specialized scan during which a mild and safe radioactive fluid is injected into your veins. This is absorbed by your overactive parathyroid gland; healthy parathyroids will not take up any radioactive particles. An X-ray of the neck is then taken which will show the overactive parathyroid and its location in the neck.
