[The use of ultrasonic tomography for assessing the spread of a primary tumor of the mucosa in the retromolar area and for choosing the surgical treatment method].

Ultrasonic examination was carried out in 31 patients with stage III-IV squamous-cell carcinoma of the retromolar mucosa. Dissemination of the tumor of the retromolar triangle into the stomach was detected in 14, into the adjacent anatomical structures in 6 patients. Combined operations with inclusion into the block of removed tissues of the involved structures were carried out due to the information obtained.
