Introduction: Xerostomia is the most common complication due to radiation–induced damage to salivary glands in head and neck cancer radiotherapy and it reduces quality of life. Parotid glands are main glands which they are account for secretion of stimulated saliva. Studies have demonstrated that mean tolerance parotid’s radiation dose under 26-30 Gy result in an increase in t...

introduction: mucoepidermoid carcinoma represents one of the most common malignant salivary gland tumors.however, the sclerosing morphologic variant is extremely rare with only 23 reported cases in the english-language literature since it was discovered in 1987. case report: herein, we describe another case that was diagnosed in a 25-year-old woman presenting with a posterior auricular mass, as...

The knowledge of normal and variant anatomy of the facial nerve is essential for safe surgery of the parotid gland. The location of a parotid mass in relation to the course of the facial nerve determines whether superficial or total parotidectomies should be performed. The variant course of the facial nerve within the parotid may endanger the nerve during parotid surgeries. The present report i...

UNLABELLED The modified rhytidectomy incision is an alternative to the classic cervicomastoidfacial approach for parotid surgery, camouflaging the scar in barely visible areas, resulting in better cosmesis. However, there are very few studies comparing the incidence of complications and functional results of patients submitted to parotidectomy through these two different approaches. OBJECTIVE...

INTRODUCTION Atheroma of the facial artery is an extremely rare disease. CLINICAL FINDINGS/PATIENT CONCERNS Herein, we report an extremely rare case of an atheroma arising from the facial artery, mimicking a parotid gland tumor. DIAGNOSES The preoperative diagnosis was a right-sided parotid gland tumor. INTERVENTIONS We performed removal of the right parotid gland tumor, via a modified fa...

an interesting case of rare multiple hydatid of parotid, brain and kidney is reported. she is a 35-year-old married woman first referred because of a swelling in the parotid region and later for neurological manifestions. on general physical examination, an abdominal mass was felt in the right hypochondrium. these multiple space-occupying 'lesions in the brain, kidney and parotid proved to be h...

A parotid fistula is a communication between the skin and a parotid duct or gland through which saliva is discharged. The most common cause of the parotid fistula is trauma. The major causes of parotid trauma in a civilian practice are penetrating injury to the parotid gland from an assault weapon or injury due to shattered glass after a motor vehicle accident. Acute suppurative parotitis can r...

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...

Parotid gland oncocytoma is an uncommon, benign salivary neoplasm composed of mitochondria-rich oncocytes. The purpose of this study was to correlate MR imaging and histopathology of parotid gland oncocytomas and to define the features that may distinguish these neoplasms from other benign and malignant parotid gland tumors. The MR imaging features in 9 patients with a pathologic diagnosis of o...
