The superior thyroid artery (STA) is the dominant arterial supply of the thyroid gland, upper larynx and the neck region. The knowledge of variations in possible patterns of origin, courses, and branching pattern of the STA is also important for surgical procedures in the neck region, such as emergency cricothyroidotomy, radical neck dissection, catheterization, reconstruction of aneurysm and carotid endarterectomy. The surgical anatomy of the STA was studied in 20 adult Anatolian preserved cadavers between the age of 40 and 70 years. The outer diameter of the STA origin was observed to be 3.53 +/- 1.17 mm. The location of the origin of the STA according to the carotid bifurcation was evaluated as above (25%), below (35%) and at the same level (40%). The distribution patterns of the STA were classified into six types depending on the branching pattern. The outer diameter of the infrahyoid branch, superior laryngeal artery, sternocleidomastoid artery and cricothyroid branch at their origins were observed to be 1.13 +/- 0.14, 1.42 +/- 0.47, 1.54 +/- 0.96 and 1.30 +/- 0.41 mm, respectively. Typical and variant glandular branching patterns were observed in 85 and 15% of the specimens, respectively. The outer diameters of anterior, anteromedial, anterolateral and posterior glandular branches were measured as 2.05 +/- 0.46, 1.41 +/- 0.43, 1.51 +/- 0.41 and 1.73 +/- 0.53 mm, respectively. It is necessary to understand the surgical anatomy of the STA to carry out successful radical neck dissection and to minimize postoperative complications in a bloodless surgical field.

Objectives: To assess the usefulness of sentinel lymph node biopsy (SLNB) in patients with early-stage oral squamous cell carcinoma (OSCC).
Materials And Methods: Seventy-five patients (mean age 62 years) diagnosed with cT1-2 N0 underwent SLNB with Tc, lymphoscintigraphy/SPECT-CT, and gamma probe detection with intraoperative histological examination of the resected sentinel lymph nodes (SLNs). Elective neck dissection was performed during the same surgical procedure of primary tumor resection when malignant deposits were detected microscopically.

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.

Rationale And Objectives: Papillary thyroid carcinoma (PTC) often metastasizes to lateral cervical lymph nodes, especially in level II. This study aims to develop predictive models to identify level II lymph node metastasis (LNM), guiding selective neck dissection (SND) to minimize unnecessary surgery and morbidity in low-risk patients.
Methods: A retrospective cohort of 313 PTC patients who underwent modified radical neck dissection (MRND) between October 2020 and January 2023 was analyzed.

Background: The objective of this study is to assess the association between age and lymph nodes metastasis (LNM) in T1 oral tongue squamous cell carcinomas (OTSCC) patients.
Methods: Patients with T1 OTSCC were extracted from the SEER database between 2005 and 2014. Univariate and multivariate logistic regression models were produced to recognize the association between age and risk factors of LNM.

Objectives: The aim of this study was to investigate the role of lymph node yield (LNY), lymph node ratio (LNR), and neutrophil to lymphocyte ratio (NLR) as prognostic factors, their impact on survival in patients with advanced laryngeal squamous cell carcinoma (LSCC).
Methods: This multicentric retrospective study included 195 patients with clinical N0 advanced laryngeal carcinoma who underwent total laryngectomy and/or total pharyngolaryngectomy over 5 years. The number of lymph nodes extracted (LNY) and the number of positive nodes were counted.
