After an introductory consultation with the anesthesia colleagues, the patient is first positioned. The base of the tongue is then positioned on the left side using the size B small bore tube. This shows a small circumscribed ulcer after monopolar coagulation from the previous operation. There are no microscopically suspicious tumor findings. A small induration is also palpable at depth. This area is now generously resected with the laser. The resection is performed up to the base of the vallecula. Then take marginal samples from the lateral, anterior, medial and basal settling areas. These are sent together with the resectate for frozen section diagnostics. The intraoperative diagnosis is as follows: Completely captured squamous cell carcinoma in fraction 1. However, metaplasia can still be seen in the anterior and medial settling area, which is why the pathology department recommends a subsequent resection. Careful resection of the medial and anterior settling area. So that a distance of 3-4 mm is created here again. Subsequently, careful hemostasis using monopolar coagulation. Then, when the wound is dry, after subtle bleeding control, the procedure is ended and all instruments are removed. After a final consultation with the anesthesia colleagues, the patient goes to the recovery room after extubation if the course of the anesthesia is normal.
