Parathyroid Surgery
The four parathyroid glands sit behind the thyroid and regulate calcium. When one becomes overactive (usually because of a benign adenoma), calcium levels rise — causing fatigue, kidney stones, bone loss, and low mood.
What it involves
Dr Marais performs targeted parathyroidectomy: pre-operative sestamibi and ultrasound localise the abnormal gland so that a small incision is enough to remove it. Intra-operative PTH measurement confirms cure before you leave theatre.
When it's indicated
Confirmed primary hyperparathyroidism (persistently elevated calcium with elevated PTH), symptomatic hypercalcaemia, kidney stones, or unexplained bone loss.
The approach
This is one of the most rewarding operations in surgery: a single hour of work can resolve years of symptoms. It requires precise pre-op imaging and calm operating — both of which are core to the practice.
