Minimally invasive thyroid and parathyroid operations: surgical techniques and pearls.

With advances in technology and greater demand for minimally invasive procedures, novel minimally invasive approaches to thyroid and parathyroid glands increasingly have been described and practiced worldwide. For the MIT approaches, the direct/cervical approaches truly can be considered minimally invasive, as they require less surgical dissection than the conventional thyroidectomy. The indirect/extracervical approaches, however, only can be considered endoscopic, however, because they generally do require greater surgical dissection. Still, among the indirect/extracervical approaches, the axillary approach appears the preferred choice, as it requires the least amount of dissection while offering the advantage of being scarless in the neck. The addition of the robot such as the de Vinci surgical system could make some of the extracervical approaches technically less challenging and improve patient outcomes. Unlike MIT, MIP has become the standard approach for surgical management of primary hyperparathyroidism caused by localized solitary parathyroid adenoma.
