OBJECTIVE To evaluate longitudinal changes in parotid volumes and saliva production over 2 years after 30 Gy irradiation. METHODS We retrospectively evaluated 15 assessable patients treated for advanced oral cancer. Eligibility criteria were a pathologic diagnosis of squamous cell carcinoma, preoperative radiation therapy with a total dose of 30 Gy delivered in 15 fractions, and the availabil...

BACKGROUND AND PURPOSE To compare intensity-modulated treatment plans of patients with head and neck cancer generated by forward and inverse planning. MATERIALS AND METHODS Ten intensity-modulated treatment plans, planned and treated with a step&shoot technique using a forward planning approach, were retrospectively re-planned with an inverse planning algorithm. For this purpose, two strategi...

BACKGROUND The most common histological diagnosis of bilateral parotid gland neoplasm is Warthin tumor. Bilateral malignant tumors of the parotid gland are extremely rare. METHODS A 60-year-old man presented with a painless mass in the right preauricular area and an MRI scan showed multiple masses in the parotid glands, bilaterally. A standard superficial parotidectomy was performed on the ri...

A parotid cyst is a well-documented clinical entity. Here we report a case of low-grade mucoepidermoid carcinoma as an occult neoplasm; a rare presentation of a parotid cyst in a 35-year-old female patient who presented with well-defined small cystic swelling of right parotid gland; cytologically consistent with a simple parotid gland cyst. The purpose of this article is to create awareness abo...

Recent progress in diagnosis, treatment, prognosis, and outcome of parotid cancer is reviewed. Modern imaging allows evaluation of the anatomical extent of the cancer and its relationship to the facial nerve, and the World Health Organization (WHO) Histological Classification facilitates accurate, consistent diagnosis. Surgery remains the treatment of choice with preservation of a functioning f...

BACKGROUND AND PURPOSE Trigeminal nerve injury or dysfunction is associated with denervation atrophy of muscles innervated by the mandibular branch of the trigeminal nerve. The purpose of our study was to evaluate the association between chronic CN V denervation and parotid gland atrophy. MATERIALS AND METHODS Twenty-six patients with chronic masticator muscle atrophy were retrospectively ide...

For determination of the dynamics of parotid urea secretion in conscious sheep, a previously standardized transit time ultrasonic flow metering system was used to measure bilateral parotid flow. Six ewes fed for ad libitum consumption were prepared under halothane anesthesia with ultrasonic probes around both parotid ducts; these ducts were also cannulated orally. After probe encapsulation (8 d...

BACKGROUND Lesions of the 'tail' of the parotid gland are difficult to assess clinically and provide a diagnostic dilemma on imaging, especially in the axial plane. Pedunculated lesions of the 'tail' of parotid can be mistaken for an extra parotid lesion. Accurate localisation of these lesions on imaging is essential to assist the clinical diagnosis, to prevent inadequate/incomplete excision an...

PURPOSE Our practice policy has been to provide intraoperative radiotherapy (IORT) at resection to patients with head-and-neck malignancies considered to be at high risk of recurrence. The purpose of the present study was to review our experience with the use of IORT for primary or recurrent cancer of the parotid gland. METHODS AND MATERIALS Between 1982 and 2007, 96 patients were treated wit...
