As previously mentioned parathyroid adenoma is a benign tumor of the parathyroid gland. The radiological tests (ultrasonography, scintigraphy, etc.) are used routinely before the surgery, for localization of the adenoma. If the adenoma localized the operation is easy to perform. A 3-4cm long incision is made on the anterior region of the neck and the adenoma is removed easily. The time of the operation is short and the recovery of the patient is quick.

However, if the adenoma localization cannot be detected with preoperative radiological tests, the surgeon's work is difficult. The surgeon must work patiently with kind manupilations. Expand the neck incision may be necessary and the time of operation getting two or three hours. Somehow the experienced surgeons find the adenoma but there is no guarantee!
