Objective  To understand anatomy of parathyroid gland and explore its application value in protection of parathyroid gland function during thyroidectomy. Methods  The literatures, which were associated with the parathyroid anatomy and hypoparathyroidism were collected. The origin, function, anatomical location, number, blood supply, lymphatic system of the parathyroid gland and its relationship with surrounding tissues of parathyroid gland and its clinical significance in the thyroidectomy, were reviewed. Results  The position of the superior parathyroid gland was relatively constant, and the inferior parathyroid gland was more likely to be ectopic. The number of the parathyroid gland was uncertain. The mainstream view was that the arterial supply of the parathyroid glands was mainly ensured by the inferior thyroid artery, a few by anastomosis of the superior and inferior thyroid arteries, or by the superior thyroid artery. However, the alternative view was that the blood supply of the parathyroid gland was not mainly derived from the inferior thyroid artery. The parathyroid gland was not easily distinguished from the adipose tissue and lymph node. Whether there was an independent lymphatic system in the parathyroid gland was still controversial. In the thyroidectomy, the parathyroid gland and its blood supply were reserved or protected by distinguishing from the Zuckerkandl tubercle, recurrent laryngeal nerve, and parathyroid specific attachment fat, which were identified by utilizing of the nanocarbon, loupe magnification, etc.. Especially in the central lymph neck dissection, the main thyroid artery trunk and its important branches should be carefully dissected or retained through the gentle capsular dissection and the correct use of energy devices for vessel sealing. The parathyroid gland in situ was reserved according to the parathyroid type. If it was not possible to be preserved, the parathyroid autotransplantation was necessary during the thyroidectomy. Conclusions  Understanding origin and location of parathyroid gland, it could provide a direction for searching parathyroid gland during thyroidectomy. Being familiar with blood supply of parathyroid gland makes it possible to protect blood vessel and preserve parathyroid gland. Gentle capsular dissection, rational use of energy device, and indocyanine green angiography seem to be more important. Number of parathyroid gland allows us to treat each parathyroid gland as the last one, if it is not preserved in situ , parathyroid gland need to be autografted to avoid hypoparathyroidism.
