Thyroid Surgery
The thyroid gland sits at the base of the neck and controls metabolism. It can develop nodules, grow into a goitre, become overactive, or — less commonly — develop cancer. Surgery removes part or all of the gland when indicated.
What it involves
Dr Marais performs both hemithyroidectomy (one lobe) and total thyroidectomy through a small horizontal incision in a natural neck skin crease. Intra-operative nerve monitoring protects the vocal cord nerves; the parathyroid glands are carefully preserved.
When it's indicated
Nodules that are suspicious on ultrasound or biopsy, goitres that are large or symptomatic, Graves' disease unresponsive to medication, and confirmed or suspected thyroid cancer.
The approach
Endocrine surgery is a special interest. Nerve preservation, calcium balance and cosmetic outcome are non-negotiable — the scar sits in a natural line and fades to be almost invisible.
