Abstract:
The knowledge of the location of the parathyroid glands is valuable in the parathyroidectomy and subtotal thyroidectomy. 319 parathyroid glands have been found in 100 cases. 80% of the parathyroid glands are situated in tile normal yet concealed position: the upper pair, above the mid of the posterior margin of the lateral lobe of the thyroid gland, while the lower pair, near the inferior 1/3 of the posterior margin of the lateral lobe. They all lie in the space between the proper capsula and fascia sheath of the thyroid gland.In subtotal thyroidectomy, the posterior part of the lateral lobe is usually preserved, it aims to protect the parathyroid gland, and is an effective procedure to prevent the injury of the recurrent nerve. Morever, it is most important to preserve the fat and loose connective tissue near the lateral lobe of the proper capsule, in order to avoid the excission of the parathyroid glands on abnormal locations (16%). In procedure of the operation on parathyroidoma or hyperparathyroidism, the first thing is to examine the condition of the lower pair parathyroid glands, which usually lie near or below the lower end of the lateral lobe and on the both sides of trachea. If the lower pair of parathyroid glands is identified to be pathological in nature, then the examination of the other pair can be performed on routine. 4% of the lower pair of the parathyroid glands are found on the both sides of trachea.A clear standard statistical diagram of the location of the parathyroid gland has been designed in this study.
