Thyroid & Parathyroid Surgery in Istanbul

Thyroid surgery sits millimetres from the nerve that powers your voice. Experience, and monitoring that nerve during surgery, is how it stays safe.

Who this is for

You may have been found to have a thyroid nodule on an ultrasound, a goitre that has grown, a biopsy result that needs surgery, or overactive parathyroid glands affecting your calcium. In each case the question is the same: does this need an operation, and if so, which one?

What happens at the first visit

Prof. Dr. Hafız reviews your ultrasound, blood tests and any biopsy results, and examines your neck and voice box. Because the voice matters so much in thyroid surgery, he checks how your vocal cords move before any operation is planned. You leave the visit knowing whether surgery is needed at all — sometimes it is not — and what he recommends.

How he protects your voice

The recurrent laryngeal nerve, which moves the vocal cords, runs directly behind the thyroid. Prof. Dr. Hafız uses intraoperative nerve monitoring — a signal that confirms the nerve is working during the operation — and has made this technology one of his career's focus areas. The parathyroid glands, which control calcium, are identified and preserved with the same care.

Thyroid and parathyroid surgery is one of Prof. Dr. Hafız's starred focus areas. He has performed these operations throughout a career that began in 1989, teaches the anatomy behind them, and uses recurrent laryngeal nerve monitoring as standard. He operates himself and follows you personally afterwards.

Prof. Dr. Günter Hafız

If you have a nodule, goitre or parathyroid problem and want a professor of this exact anatomy to look at it — or you have been told you need surgery and want certainty first — book a consultation and bring your ultrasound and blood results.

Does every thyroid nodule need surgery?
No. Many nodules only need observation. Whether yours needs surgery depends on its size, its appearance on ultrasound and the biopsy result, and that is exactly what the consultation clarifies.
Will my voice change after thyroid surgery?
Protecting the voice is central to how Prof. Dr. Hafız operates, including monitoring the voice nerve during surgery. He will explain the risks honestly for your specific case before you decide.
Will I need to take medication after surgery?
If the whole thyroid is removed, thyroid hormone replacement is usually needed. If only part is removed, it depends. This is discussed with you before the operation, never after.
