Hypoparathyroidism is a common complication following thyroidectomy, resulting in significant disturbances in calcium homeostasis due to low parathyroid hormone (PTH) levels. This comprehensive review examines the risk factors associated with transient and permanent hypoparathyroidism post-thyroidectomy, emphasizing surgical, patient-related, and perioperative factors. Transient hypoparathyroidism, characterized by temporary hypocalcemia resolving within weeks to months, is often managed with short-term calcium and vitamin D supplementation. In contrast, permanent hypoparathyroidism persists beyond six months post-surgery, necessitating lifelong supplementation and potentially PTH replacement therapy. The review delves into the anatomy and physiology of the parathyroid glands, mechanisms leading to hypoparathyroidism, and incidence rates. Surgical factors such as the extent of thyroidectomy, surgeon expertise, and intraoperative parathyroid gland preservation are critical in determining the risk of hypoparathyroidism. Patient factors, including age, sex, pre-existing conditions, and perioperative management, influence outcomes. Diagnostic and monitoring strategies, along with management protocols for both transient and permanent hypoparathyroidism, are discussed. Prevention strategies, emerging research, future surgical techniques, and intraoperative monitoring directions are highlighted to improve clinical outcomes. This review aims to enhance understanding, inform surgical practices, and optimize postoperative care to minimize the incidence and impact of hypoparathyroidism in thyroidectomy patients.

Objective: This study aimed to assess the degree of effect of central lymph node dissection on postoperative hypoparathyroidism incidence.
Methods: The incidence of postoperative hypoparathyroidism was compared between patients receiving thyroidectomy with central neck dissection for papillary thyroid carcinoma and those undergoing thyroidectomy for benign thyroid diseases (thyroid follicular adenoma and/or nodular goiter) necessitating surgical intervention.
Results: The incidence of postoperative hypoparathyroidism was not significantly different between the groups of lobe thyroidectomy for benign thyroid diseases and lobe thyroidectomy with ipsilateral central lymph node dissection for papillary thyroid carcinoma (immediate: 9.

Background: This study aimed to evaluate the prognostic outcomes of thyroidectomy extent in unilateral TNM T1 or T2 papillary thyroid carcinoma with lateral lymph node metastasis.
Methods: Retrospective data were collected from unilateral papillary thyroid carcinoma patients with unilateral lymph node metastasis who underwent surgery at Qilu Hospital of Shandong University from 2011 to 2022. Patients were categorized into 2 groups based on the extent of the thyroidectomy (total thyroidectomy versus lobectomy).

Introduction And Importance: Primary hyperparathyroidism (PHPT) is a frequent complication to multiple endocrine neoplasia type 1 (MEN1), presenting challenges due to increased risk of multi-gland disease and recurrence post parathyroidectomy (PTX). This case report examines the management of PHPT in a MEN1 patient, emphasizing possible benefits from intraoperative parathyroid autofluorescence imaging (AF).
Case Presentation: A 21-year-old woman with MEN1 presented with mild hyperparathyroidism symptoms in 2014.
