Objectives/hypothesis: Routine identification of all four parathyroid glands has been advocated as a means of reducing rates of postoperative hypocalcemia and inadvertent parathyroidectomy. The object of the present study was to investigate whether identification of more parathyroid glands during thyroidectomy performed by capsular dissection technique had any impact on incidence of postoperative hypocalcemia and unintentional parathyroid resection.
Study Design: Prospective cohort study of consecutive patients undergoing total thyroidectomy by capsular dissection technique over a 3-year period. Exclusion criteria included performance of concomitant central neck dissection, hyperparathyroidism, revision surgery, and invasive cancer.
Methods: The number of parathyroid glands identified intraoperatively was recorded. No effort was made to find glands that were not obviously apparent during the course of dissection. Patients were not placed on routine calcium supplementation.
Results: The final study population consisted of 126 patients. The mean number of parathyroid glands identified was 2.3. The incidence of biochemical (any postoperative calcium <2 mmol/L) and clinical hypocalcemia was 22.2% and 10.3%, respectively. Patients in group A (0-2 parathyroids identified) had a significantly lower incidence of clinical hypocalcemia than patients in group B (3-4 parathyroids identified) (3.2% vs. 17.1%, P = .02). The differences in biochemical hypocalcemia were not significant (16.1% vs. 28.1%, P = .13). The incidence of inadvertent parathyroidectomy was 9.5%. There was no difference between the groups in incidence of inadvertent parathyroidectomy (9.7% vs. 9.4%, P = 1.0).
Conclusions: Routine identification of all four parathyroid glands is not necessary in thyroidectomy performed using capsular dissection technique.

Endocrine surgery in multimorbid, frail and geriatric patients is increasing, is often urgent and characterized by special risk constellations. Successful parathyroid gland surgery nearly always results in a marked improvement, irrespective of the specific risk profile of the patient. Except for critical intubation and mediastinal interventions in the risk profile, surgery of the thyroid glands is predominantly beneficial and justifiable even in frail patients.

Background: The importance of parathyroid gland preservation in thyroid surgery has been well recognized; however, the rapid identification of the parathyroid gland, particularly the inferior parathyroid gland (IPG), remains challenging. This study aimed to evaluate the effectiveness of retrograde inferior parathyroid protection technique (RIPPT) based on thymus preservation.
Methods: A total of 236 patients were enrolled in this study between August 2019 and December 2020.

Background: Radioactive iodine (RAI) is a common treatment for various thyroid diseases. Previous studies have suggested susceptibility of parathyroid glands to the mutagenic effect of RAI and the development of primary hyperparathyroidism (PHPT). We tested the possible link between prior RAI treatment, disease presentation, and treatment outcomes.

Tertiary hyperparathyroidism is characterized by hypercalcemia resulting from autonomous parathyroid hormone production and usually occurs after a prolonged period of secondary hyperparathyroidism. This condition can be a complication of X-linked hypophosphatemia (XLH), a rare genetic disease characterized by renal phosphate loss and consequent hypophosphatemia. Parathyroidectomy is considered the first-line therapy but surgical intervention can be complicated by hungry bone syndrome.
