| | Parathyroid Disease: Diagnosis and Treatment |
 | | Parathyroid adenomas generally are not palpable on physical examination. | | | Secondary hyperparathyroidism entails hyperplasia of the parathyroids secondary to dysfunction of another organ system. | | | The greatest development within the area of parathyroid surgery has been a minimally invasive approach, which refers to the directed, unilateral resection of a solitary thyroid adenoma. |

| | Parathyroid Disease (Feb.1997) |
| | Vocal cord paralysis as a result of recurrent laryngeal nerve damage occurs in less than 1% of parathyroid surgery, and can be avoided by careful dissection of the RLN and keeping it in full view during surgery in the area. | | | Proponents for localization prior to every parathyroid surgery argue that since greater than 80% of the cases of hyperparathyroidism are due to adenomas, surgical time and consequently morbidity can be decreased if the adenoma is localized prior to surgery. | | | The concept of performing localization studies previous to the first parathyroid surgery, however, is controversial because of the 95% success rate in experienced hands. |

| | The cryopreservation of parathyroid tissue for possible later implantation is an option in units with specific experience of this technique. | | | A "focused" approach following imaging of the parathyroids my permit a smaller surgical scar and can be open or using minimally invasive techniques (MI) MI surgery should only be performed by those surgeons explicitly trained in the procedure, (and will probably be applicable in no more than 50% of patients). | | | The operation should be conducted by a surgeon experienced in parathyroid surgery. |

| | Parathyroid Surgery |
| | Focused and traditional parathyroid operations each have their own unique requisites, advantages, and disadvantages, but each may prove equally effective if applied appropriately to the individual patient in consultation with a surgeon experienced with each approach. | | | There are two main approaches to parathyroid surgery which can be accomplished using local anesthesia and small incisions (minimally invasive surgery) with the possibility for same day discharge after a period of observation (6 hours). | | | In order for the focused approach to be successful, additional intraoperative monitoring is also necessary in order to confirm that a patient is cured of their disease following removal of the single adenoma. |

| | Most parathyroid surgeons do not believe that the intra-operative probe is necessary because it does not improve the success rate of parathyroid surgery and it only makes the procedure more complicated. | | | It is important to note that inexperienced surgeons may only perform the unilateral approach when using local anesthesia, however, an experienced surgeon will be able to use both approaches under local or general anesthesia with very little difference between the two in terms of recovery time, hospital stay, incision size, duration of operation and complications. | | | here are two main approaches for parathyroid surgery: unilateral (one side of the neck) and bilateral (both sides). |

| | Since hyperparathyroidism was first described in 1925, the symptoms have become known as "moans, groans, stones, and bones." The primary treatment for this disease is the surgical removal of the faulty gland. | | | A Sestamibi scan is often used to determine which parathyroid gland(s) are responsible for overproduction of parathyroid hormone. | | | The sole purpose of the parathyroid glands is to regulate the calcium level in our bodies within a very narrow range so that the nervous and muscular systems can function properly. |

| | This condition is sometimes successfully treated by the administration of the hormone. | | | Calcium is intimately involved not only in the formation of bone, but also in the functioning of the nervous system; thus hypoparathyroidism, the disease associated with a deficiency in parathyroid hormone secretion, is characterized by muscle spasms leading eventually to generalized convulsions and various psychiatric symptoms. | | | Hyperparathyroidism, the result of oversecretion of the hormone, often leads to the resorption of bone and can only be treated by the surgical removal of all of the parathyroid glands, which can be found in unusual locations. |
