Major Types of Parahtyroid Glands Location and Their Relationship with the Post-Operative Hypoparathyroidism

We have performed 130 operations on the thyroid gland. The spectrum of surgical interventions on the thyroid gland was as follows: hemithyroidectomy was performed for 49.2% of patients, thyroidectomy – for 23.1% of patients and thyroidectomy with central and peripheral lymph node dissection – for 27.7% of patients. All patients were performed the determination of PTG type and their visual assessment.Types A and B1 are rarely traumatized during operations on thyroid gland, PTG of type B2 and B3, C practically in almost all cases are damaged or become ischemic in a varying degree, therefore, types B2, B3 and C can be considered as the risk factors for the development of postoperative HPT, and in case of type B2 of PTG they were technically difficult to be isolated without damage, and in the B3 and C types it is generally difficult to keep them intact. Determination of the type of PTG and their visual assessment is the basis for solution to the problem of preservation of PTG in place or of their autotransplantatio
