[Ultrasonographic intraoperative evaluation of neoplastic changes in the tongue, tonsil, larynx, salivary and neck masses--preliminary report].

UNLABELLED: The new diagnostic method, intraoperative ultrasound is presented. There are very few publications in the literature, but they mainly concern the application of transcutaneous ultrasound in localizing the abscesses, their puncture and drainage. Intraoperative imaging of tongue, tonsil, larynx tumors, submandibular and parotid glands and neck masses have been provided by means of a linear 7.5 MHz probe in Poznań ENT Dept. K. Marcinkowski University of Medical Sciences. The application of this method is pioneer and new. The aim of the study was to compare the sensitivity and the specificity of preoperative, transcutaneous ultrasound with the intraoperative one, to assess how the new method influences the extensiveness of the performed procedures and sonographic-surgical correlation of safety margins. MATERIAL: 5 patients with parotid tumors, 4 with tongue, 6 with tonsil and 6 with larynx cancers have been examined. In 13 of them, apart from primary site diagnostics, the neck masses have been assessed. The imaging documentation is presented and the preliminary conclusions concerning the usefulness of this method have been drown.
