Preoperative evaluation of the precise localization of the intrapartotic facial nerve is essential for the ENT surgeon to assess the risk of nerve damage during parotid tumor excision, and inform the patient of the risk of post-paralyzed facial nerve palsy. procedure
1. st visit: Inclusion, parotid MRI 3Tesla high resolution with specific sequences and gadolinium injection performed at the A. de Rothschild Foundation. Evaluation by two radiologists of the exact position of the parotid tumor with respect to the trunk of the facial nerve and its first branches, classified into two categories: contact (≤ 5 mm) or distance (> 5 mm).
2. nd visit: Surgical intervention of the parotid tumor. The surgeon will specify the same data as those collected by the radiologists after the MRI. The surgeon will not be aware of the data concerning the ratios of parotid tumor to facial nerve collected on MRI sequences for research purposes.

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 evaluat...
In this study, the investigators will evaluate the clinical usefulness of 3 dimensional double echo steady state MRI (3D-DESS MRI) for functional preservation of the facial nerve during pa...
Open-label, non-randomized, dose escalation trial of AAV2hAQP1 administered via Stensen's duct to a single parotid gland in subjects with radiation-induced xerostomia The objectives are to...
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 prospec...
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 cel...
Here we present a patient with a parotid secretory carcinoma (SC) with high-grade transformation. A 65-year-old female was referred to our hospital due to a gradually growing right parotid tumor disco...
Warthin tumor is described using various terms, such as papillary cystadenoma lymphomatosum, adenolymphoma or monomorphic adenoma. It is a medical condition related to the salivary glands, namely a be...
A variety of neoplastic and non-neoplastic lesions of the parotid gland can present with a predominantly cystic architecture, and although radiologists frequently encounter cystic parotid tumors, othe...
Warthin-like mucoepidermoid carcinoma is a newly recognized rare entity and could be misdiagnosed as a benign Warthin tumor. We report such a case of a 36-year-old male who presented with a left parot...
Schwannomas are benign tumors which arise from Schwann cells and take place along peripheral nerves. Extra-temporal facial nerve schwannomas are infrequent and present as painless masses in the paroti...
A tumor of both low- and high-grade malignancy. The low-grade grow slowly, appear in any age group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the salivary gland and produce lymph node and distant metastases. Mucoepidermoid carcinomas account for about 21% of the malignant tumors of the parotid gland and 10% of the sublingual gland. They are the most common malignant tumor of the parotid.

Tumors or cancer of the PAROTID GLAND.
The region of the face on either side, around the PAROTID GLAND.
A benign tumor characterized histologically by tall columnar epithelium within a lymphoid tissue stroma. It is usually found in the salivary glands, especially the parotid.
Diseases involving the PAROTID GLAND.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
