[The actual role of bilateral neck exploration in the treatment of primary hyperparathyroidism].

Surgery is the only curative treatment for primary hyperparathyroidism (pHPT). Surgical exploration is recommended for all patients with biochemically documented pHPT and signs or symptoms of the disease. Some patients are asymptomatic, others have subtle symptoms that disappear after parathyroid surgery. Felix Mandl successfully performed the first parathyroidectomy in 1925, using a bilateral neck exploration (BNE) with examination of all four glands and this remained the procedure of choice for pHPT into the 1990s. As over 80% of pHPT cases are due to a single parathyroid adenoma, many authors have questioned the need of BNE and have proposed directed unilateral approaches, termed "mini-invasive parathyroidectomies". The aim of this report is to define which is the actual role of the conventional surgical approach to pHPT.
