This operation is used for successfully localised primary hyperparathyroidism where we know where the abnormal gland is. It is the operation we usually offer in over 95% of cases. It is a 2-3cm incision in the neck over where the gland is. It is done under a general anaesthetic and nerve block to smooth recovery. It carried out as a day case. Frozen section and intra-operative PTH measurement can have a role in a few cases, but don't reduce the risk of failure by any more than an additional 1%. The chance of surgery being successful in first time surgery is around 96-97% without using them.
No operation is without some risks and these are discussed here.
