After active patient identification, the patient is taken to the operating theater. Introductory consultation with the anesthesia department. Carrying out the team time-out. Induction of anesthesia by the anesthesia colleagues. Positioning of the patient by the surgeon. Insertion of the reinforced mouth retractor and looping of the tip of the tongue. Palpatory identification of the tumor borders in the area of the right-lateral, posterior third of the tongue. Marking of the resection margins using the monopolar needle. Successive resection of the tumor while maintaining a sufficient safety distance. Punctual hemostasis is repeatedly performed in between. Resection of the tumor in toto and suture marking. Repeated hemostasis using bipolar coagulation. If the macroscopic safety margin is sufficient, definitive margin samples are deliberately not taken. If the wound bed is dry, the operation is now completed without complications. Remove the tongue suture and the reinforced mouth guard. Final consultation with the anesthetist. Postoperatively, please attend the interdisciplinary tumor conference after receiving the definitive histology. If rejection of the necessary adjuvant therapy is expected, a clear recommendation should be made to the patient.
