Introductory consultation with the anesthesia department. Positioning of the patient. Insertion of the mouth guard. Suturing of the tongue. Start the resection from the tumor border facing the tip of the tongue with a safety margin of about 2 - 3 mm. The tumor appears to be very extensive and not too deep. Due to the extensive growth, however, a very large resection area is visible. The resection is performed on all sides about 2 - 3 mm into the healthy tissue. The resection is performed with successive hemostasis. The tumor can ultimately be resected and removed in a circular fashion. A very extensive wound surface is revealed, which is why reconstruction may now be necessary depending on the functional outcome. As a result, the decision was made not to perform a single-stage neck dissection on both sides in order to keep the option of reconstruction open. For this reason, repeated hemostasis. Injection of local anesthetic into the wound area for postoperative pain reduction. Final consultation with the anesthetist. Completion of the procedure after removal of all instruments. Planning of neck dissection on both sides with level I a on both sides at intervals.
