First consultation with the anesthesia department. Then extremely difficult intubation of the patient. Tracheoscopy beforehand. Advancement of the 0° scope through the glottic plane into the trachea. Inconspicuous mucosal conditions in the area of the trachea. No abnormalities in the outlet of the segmental bronchi on either side. Now intubation of the patient. First advance the esophagoscope into the stomach. Careful reflection back. No abnormalities of the mucosa in the area of the esophagus. Now inspect the subglottis, glottis and supraglottis, after adjustment with the smallest small bore tube. Extremely severe exposure. No evidence of tumor growth in the area of the larynx. Now inspection of the hypopharynx and the postcricoid region. Inconspicuous mucosal conditions here too. Inspection of the oropharynx on both sides. Particularly in the region of the base of the tongue, the mucosa is very edematous but smooth, with no evidence of exophytic tumor growth. Now inspection of the oral cavity. There is an exophytic tumor in the area of the middle third of the tongue, which most likely corresponds to a malignoma. The extension is approx. 2 cm. Careful disluxation of the tongue and resection of the tumor with a clear safety margin. The tumor is resected with the electric needle with a sufficient safety margin on all sides. Marking of the specimen. As far as can be assessed intraoperatively, the tumor can be removed in a healthy state. Further procedure depends on the histology. After careful hemostasis, the procedure is completed. Final consultation with the anesthesia department. The patient is transferred to the recovery ward.
