[Echography and parotid tumors].

Morphological criteria obtained from ultrasonic exploration of 82 parotid tumors were compared with histological findings. Precise determination was possible of the size of the tumor, its cystic or solid nature, and the pre-operative evaluation of its benign or malignant nature. In spite of certain deficiencies, the safety, rapidity of execution, and reliability of ultrasonography make it a complementary investigation of choice for all isolated nodular lesions in the parotid region before surgical exploration, which remains indispensable.
