We herein describe a case of accessory parotid gland tumor, including diagnosis and surgical approach. The accessory parotid gland is salivary tissue separated from the main parotid gland and lying on masseter muscle. It has secondary duct empting into the Stensen's duct. The accessory parotid gland exists in 21-61 % of individuals. However, the appearance of an accessory parotid tumor is rare,...

  To detect the effects of sympathomimetic drugs with selective action on β1 and β2 adrenoceptors, male albino mice were treated by intraperitoneal administration of dobutamine and terbutaline for 15 days. Three groups of mice were selected as dobutamine, terbutaline and control groups, respectively. At the end of the experiment, the animals were sacrificed and the parotid glands were removed a...

BACKGROUND Accessory parotid gland tissue is salivary tissue adjacent to Stensen's duct that is distinctly separate from the main body of the parotid gland. Surgical removal of an accessory parotid mass is usually accomplished through an external neck incision. However, this procedure inevitably results in a neck scar. METHODS We report the case of a 55-year-old man with an accessory parotid ...

conclusions there was no statistically significant difference in the parotid absorbed dose between spiral tomography and a panoramic radiograph (p value = 0.18). the overall results of this study were similar to other studies. results for the tube side parotid, the average absorbed doses in spiral tomography of the anterior and posterior parts of the maxilla and mandible, with the 2 mm slice th...

The sparing of the parotid glands in the treatment of head and neck cancers is of clinical relevance as high doses to the salivary glands may result in xerostomia. Xerostomia is a major cause of decreased quality of life for head and neck patients. This paper explores the relationship between the overlap of the target volumes and their expansions with the parotid glands for helical delivery pla...

BACKGROUND AND AIM: Due to increasing use of X-rays in diagnosis and treatment of diseases, this study aimed to measure and compares the absorbed dose in a number of sensitive organs of head and neck in different radiographic techniques.METHODS: Thermoluminescence dosimeter (TLD) and a male equivalent RANDO phantom were used to measure the absorbed dose in organs. The dosimeters were set in cer...

INTRODUCTION Acinic cell carcinoma is a rare form (2-4%) of parotid tumor. It is, however, the most frequent form of bilateral parotid tumor and the second most frequent form in children. CASE REPORT A 22-year-old man had several years' history of left parotid tumor, discovered to be acinic cell carcinoma. MRI found a synchronous contralateral tumor of the same histologic nature. DISCUSSION...

PURPOSE We hypothesized that a difference in restricted diffusion would exist in patients with connective tissue disorders (CTD) as compared with those without CTD. Our purpose was to determine whether the apparent diffusion coefficient (ADC) measurement could be used to identify parotid abnormalities in patients with CTD. METHODS One neuroradiologist, who was unaware of patient histories, re...

A common side effect of radiotherapy used in the treatment of oral cancer is the occurrence of structural and physiological alterations of the salivary glands due to exposure to ionizing radiation, as demonstrated by conditions such as decreased salivary flow. The present study evaluated ultrastructural alterations in the parotid glands of rats receiving a fractionated dose (1,500-cGy) of radia...
