Parotid Tumor Clinical Trial
Official title:
Study of the Facial Nerve in MRI 3T in the Preoperative Assessment of Parotid Tumors
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.
