in these study we analyze pattern of parotid gland neoplasms according to histopathological types, most common type clinical presentation and type of surgical treatment(superficial parotidectomy or total parotidectomy radical parotidectomy
Parotid neoplasm consists of a wide range of benign and malignant lesions, and parotidectomy has been the mainstay for management of these neoplasms. Within the parotid gland there are branches of the intra-parotid facial nerves, which are tiny in calibre and are prone to injury to injury during operation. It has been reported in recent retrospective view that the incidence of temporary and permanent facial nerve injury were 9.2% and 5.2% respectively, the risk of which increased with old age, malignant tumour and revision surgery. Traditional the incidental of facial nerve injury is reduced by intra-operative facial nerve monitoring and surgical magnification, while imaging has limited role in aiding this purpose. However with advancement in MRI technique high resolution three-dimensional sequences (i.e. neurogram sequences) are available for better visualization of branches of facial nerves. The investigators would therefore aim to demonstrate additional efficacy of these techniques and also to compare with conventional 3D post-contrast anatomical imaging studies in the localization and visualization of the facial nerve branches in patients with tumour. With better pre-operative imaging, the investigators hope to reduce the chance of facial nerve injury in these patients.
Comparison between Ultrasound-Guided Ethanol Sclerotherapy (UGES) & surgical excision in management of warthin tumor of parotid gland.
This clinical trial studies the effect of customized 3 dimensional (3D) printed oral tents on patients with head and neck cancer who are receiving radiotherapy. Oral stents are made from the impression of patients' mouth and cover patients' teeth and gums during radiation therapy. A customized, 3D-printed oral stent may help to reduce mouth blisters and/or sores that may develop in patients while receiving head and neck radiation therapy.
1. st visit: Inclusion, 3Tesla injected parotid MRI performed as part of routine care for characterization, to which two specific high resolution sequences will be added. Evaluation of the exact position of the parotid tumor relative to the trunk of the facial nerve and its first branches, classification into two categories: on contact (≤ 5 mm) or at a distance (> 5 mm). 2. nd visit: Surgical intervention of the parotid tumor. The surgeon will specify the same data as that collected by the radiologists after the MRI. 3. rd visit: Post-operative consultation in the week following the intervention. The surgeon will look for the occurrence of post-operative facial paralysis.
The aim of the study is to evaluate concordance between the facial nerve's path in the parotid evaluated by radiologist in preoperatively and the facial nerve's path in the parotid evaluated by surgeon in peroperatively.
Parotid gland tumors are mostly treated surgically, but the extent of parotidectomy is decided upon preoperative work-up information. Preoperative management generally includes clinical evaluation, collection of a pathological sample, most often through fine-needle aspiration cytology (FNAC), and imaging. FNAC, despite its high sensitivity and specificity, has the drawback of an approximately 20 per cent rate of nondiagnostic or indeterminate result. Magnetic Resonance Imaging (MRI) provides the best morphological description of the lesion, which is helpful to the surgeon for the planning of the intervention. Recently, advanced functional techniques have been introduced, in association to the conventional morphologic ones: diffusion-weighted imaging (DWI) and dynamic contrast-enhanced imaging (DCEI) demonstrated the ability to provide information about the possible histological origin of parotid lesions. Multiparametric MRI (mp-MRI) comes from the combination of anatomical and functional sequences. The Authors postulate that mp-MRI evaluation may be able to provide information not only about the extension of the lesion, but also about histology, with a high accuracy, at least comparable to ultrasound-guided FNAC. In the present study, the Authors aim to define the value of FNAC and mp-MRI in the preoperative management of parotid gland tumors, comparing their success intended as the capability of the exam to be both diagnostic and accurate in formulating the correct histological suspect of malignancy. Participants are patients affected by parotid gland neoplasms, candidates for surgical resection. The lesion will preoperatively be assessed with both clinical evaluation, ultrasound-guided FNAC and mp-MRI in our Institution. Mp-MRI includes conventional sequences, DWI and DCEI; its interpretation will allow the definition of the suspect histology. FNAC and mp-MRI suspects will be compared to the final histopathological report after surgical removal of the neoplasm. The study considers a total of 100 patients, of whom 50 are analyzed retrospectively (being already operated after obtaining both FNAC and mp-MRI preoperatively) and the remaining 50 to be enrolled prospectively.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether intensity-modulated radiation therapy or 3-dimensional conformal radiation therapy is more effective in decreasing hearing loss in patients undergoing radiation therapy for parotid gland cancer. PURPOSE: This randomized phase III trial is studying intensity-modulated radiation therapy to see how well it works compared with 3-dimensional conformal radiation therapy in decreasing hearing loss in patients who have undergone surgery for parotid tumors.
Liberal use of fine needle aspiration biopsy of parotid gland masses is controversial. All information regarding this procedure has been retrospective. Our objective is to evaluate prospectively the diagnostic accuracy of the test, alone and when associated to clinical and/or radiologic data.
