Primary hyperparathyroidism can easily be treated with minimally invasive surgery via a “buttonhole” incision in the neck. Minimally invasive parathyroidectomy takes about 15 minutes from start to finish. Undiagnosed or untreated hyperparathyroidism can progress to irreversible complications such as renal failure and hypertension with secondary detrimental effects. Doctor Apffelstaedt has introduced this advanced procedure in South Africa in 2016.
