Background And Objectives: Total thyroidectomy is indicated in most cases with postcricoid carcinoma, circumferential hypopharyngeal carcinoma and in advanced laryngeal carcinoma. Persistent hypoparathyroidism is a frequent complication after total thyroidectomy which is difficult to manage unlike hypothyroidism. This study was to assess the feasibility of parathyroid gland autotranplantation after total thyroidectomy in advanced carcinomas and their effectiveness in preventing persistent hypoparathyroidism.
Methods: This study included 26 patients with hypopharyngeal and laryngeal carcinoma presented to National Cancer Institute, Cairo University. Total thyroidectomy and total parathyroid gland excision were performed as a part of adequate oncologic surgical procedure. The parathyroid glands were identified, resected and stored in iced saline. Histological confirmation was necessary before implantation into separated muscle pockets in the anterior forearm muscles. Regular samples were drawn to assess serum parathormone and calcium levels.
Results: All patients experienced hypocalcaemia within 1-5 days after operation. Only one patient experienced parathyroid graft failure while the remaining patients were normocalcemic during follow up after surgery, indicating functioning parathyroid grafts.
Conclusions: Parathyroid gland autotranplantation is a simple safe technique with high success rate in preventing persistent hypoparathyroidism after total thyroidectomy in surgical management of advanced hypopharyngeal and laryngeal carcinomas.

Aim: Thyroid nodules, based on high-resolution ultrasonography (HRUS), are among the most common endocrine abnormalities that affect the general population because of their high estimated prevalence rates. Fine needle aspiration cytology (FNAC) is a safe, cost-effective modality to differentiate between benign and malignant thyroid nodules based on the Bethesda System for Reporting Thyroid Cytopathology (BSRTC), thus avoiding unnecessary surgery. However, categories III and IV of BSRTC remain a controversial issue in clinical practice, encompassing a wide range of risks of malignancy.

Background: This study aimed to compare the rates of postoperative and permanent hypocalcemia between postthyroidectomy indocyanine green angiography and indocyanine green angiography-guided thyroidectomy performed intraoperatively for identification and preservation of the parathyroids.
Methods: We undertook a retrospective study of 2 cohorts of patients with thyroid cancer undergoing total thyroidectomy and central neck dissection. The first cohort (control group) included patients who underwent postthyroidectomy indocyanine green angiography to predict parathyroid function by scoring the degree of fluorescence (0, black; nonvascularized; 1, gray/heterogeneous: partially vascularized; and 2, white: well vascularized), and the second cohort (angiography-guided thyroidectomy) included patients undergoing initially indocyanine green angiography-guided thyroidectomy to identify the feeding vessels of the parathyroid glands followed by postthyroidectomy indocyanine green angiography.

Introduction: Thyroid neoplasms are the most common malignancy of the endocrine system, representing 3.8% of new cancer cases, and it is the ninth most common cancer overall. The immuno-histochemical marker Hector Battifora Mesotheilial-1 (HBME-1) is a monoclonal antibody that now finds its diagnostic utility as a positive marker for well-differentiated thyroid carcinomas.

The choice between total thyroidectomy (TT) and subtotal thyroidectomy (STT) can affect postoperative complications and long-term outcomes in these patients. This study aimed to investigate postoperative complications and long-term outcomes in patients who underwent TT and STT. This retrospective study investigated 1.
