Abstrakt: Objectives: The existence of tumour cells on the surgical margin can be shown in frozen sections. However, there has been no method to obtain information about surgical clearance intraoperatively. We propose a simple method to confirm the surgical clearance of tongue carcinomas during surgery.
Methods: Just after the resection of a tumour in a conventional manner, the resected fresh specimen was immersed in a gelatine solution, maintaining its original shape and orientation, and refrigerated for solidification of the gelatine. Then ultrasound observation of the gelatine-embedded specimen was performed from the surface of the gelatine.
Results: Very fine images could be obtained easily and without any specialist skills.
Conclusions: With this method, the operator can easily obtain information about surgical clearance during the operation.
