BACKGROUND Indications for thyroidectomy during laryngectomy are controversial. We examined whether clinicopathologic features can predict thyroid gland involvement, and the prognostic effect of thyroid gland involvement in patients undergoing total laryngectomy. METHODS The study set out to review preoperative assessment, operation findings, pathologic findings, and follow-up data. RESULTS...

Introduction: Computed tomography (CT) consists of 11% of all imaging methods, but accounts for approximately 67% of radiation exposure due to diagnostic cases. More than one-third of all CT scans are done in the head and neck area. The thyroid gland is irradiated during CT head and neck. According to studies, this gland has the highest levels of radiation-induced cancer, and i...

Introduction: Thyroid hormones play an important role in the regulation of metabolism, maturity and reproduction. Thyroid dysfunction affects almost all endocrine glands such as pituitary and testis. The aim of this study was to investigate alterations of testosterone and luteinizing hormone (LH) serum levels as well as weights of thyroid gland and testes in methimazole (MMI)-induced hypothy...

metastasis to the oral region is very rare and accounts for less than 1% of oral malignant tumors. breast, lung, kidney, adrenal, gastro intestinal tract and prostates are most common primary tumors from which metastasis to oral region occur frequently. metastasis from thyroid gland is extremely rare to oral region. we present an unusual case of metastatic follicular carcinoma of thyroid in max...

background  it is remain a main concern that pediatric chest radiographies contribute to the significant radiation exposure to the thyroid gland as a more susceptible organ to radiation induced cancer. the aim of this study was to evaluate the entrance surface dose (esd) of pediatric chest radiography compared to the diagnostic reference levels (drl) and evaluation the efficacy of the lead (pb)...

An ectopic location of the thyroid gland usually occurs in the midline, starting anywhere from the tongue to the diaphragm. The occurrence of an ectopic thyroid gland in a non-midline site is extremely rare. We report a 32-year-old Malay woman with an aberrant thyroid gland presenting as a parapharyngeal lesion. She had a normally functioning thyroid gland. An ectopic thyroid should be consider...
