parotid stafne bone defect is a very rare and infrequent variant, which is located on the buccal or lingual surface of the mandibular ascending ramus. in this paper, a case of parotid stafne defect, which was incidentally discovered during dental radiographic examination, is reported. this bone defect was observed as a lucent oval-shaped defect on the lingual aspect of the right mandibular ramu...

Introduction Parotid gland squamous cell carcinoma is an uncommon aggressive neoplasm with poor prognosis. Aural polyps are usually the presenting features of chronic suppurative otitis media, tuberculous otitis media, and adenoma or carcinoma. The malignant aural polyp is very rare.

Abstract Parotid gland is a rare site of metastasis from gastrointestinal (GI) tract primary cancer. Here, we present an interesting case report parotid unknown with probable lower GI as cancer, normal colonoscopy and upper endoscopy. This highlights the importance immunohistochemistry in taking treatment decisions during dilemmatic situations.

PURPOSE To concurrently quantify the radiation-induced changes and temporal evolutions of parotid volume and parotid apparent diffusion coefficient (ADC) in nasopharyngeal carcinoma (NPC) patients treated by intensity-modulated radiotherapy by using magnetic resonance imaging (MRI). MATERIALS AND METHODS A total of 11 NPC patients (9 men and 2 women; 48.7 ± 11.7 years, 22 parotid glands) were...

sialography is the retrograde injection of an iodinated contrast agent into the ductal system of salivary glands and this technique is the only method capable of adequately demonstrating the status of the ductal system. one of the indications of sialography is classification of the salivary ductal system fistulae. this classification has important prognostic and therapeutic values. in the prese...

BACKGROUND Radiation-induced parotid damage is a common complication in patients with nasopharyngeal carcinoma (NPC) treated with radiotherapy to head and neck region, which severely reduce the life quality of those patients. The aim of this study was to early evaluate the changes of irradiated parotid glands with T2 mapping and mDIXON Quant imaging. METHODS Forty-one patients with NPC underw...
