First induction of anesthesia. Then perform a rigid tracheoscopy. Inconspicuous mucosal conditions here. The patient is then intubated without any problems. Now insertion of the flexible esophagoscope under insufflation. Pre-insufflation into the stomach. Here and on retraction in the area of the esophagus, regular mucosal relief without evidence of exophytic tumor growth. Now repositioning. Insertion of a mouth guard and insertion of a Kleinsasser C-tube. Inspection of the structures of the oropharynx, hypopharynx and endolarynx. Regular mucosa is visible on all sides. Now insertion of an oral retractor. Snare the tongue and inspect the edge of the tongue. On the right side, an approx. 1 x 1.5 cm large, coarse, centrally ulcerated mass can be seen in the posterior third. Demonstration of the findings to <CLINICIAN_NAME>. He recommended a complete excision with a safety margin using an electric needle and suture marking. Therefore, proceed according to this recommendation. First mark the resection margins. Then successively cut the fibers of the tongue musculature. Strict care is taken to resect the healthy tissue with a safety margin of a few mm. The tumor can be completely removed and is then suture-marked. Finally, bipolar coagulation is performed to stop the bleeding and, if the wound is dry, the procedure is completed without complications.
