Introductory consultation with the anesthetist. Then advance the 0° optic through the glottic plane into the trachea. Inconspicuous mucosal conditions in the area of the trachea up to the exit of the segmental bronchi. Intubation of the patient. Then inspection of the hypopharynx on both sides, the postcricoid region and the oropharynx. In the area of the base of the tongue, the mucosal conditions are unremarkable, also in the area of the hypopharynx and the postcricoid region. In the area of the left tonsil, the mucosal conditions are unremarkable. The floor of the mouth is also completely normal on inspection and palpation. Inspection of the right tonsil. A tumorous mass is seen here, which completely covers the tonsil and also extends somewhat laterally. Then elevation of the soft palate. Inspection of the nasopharynx. Inconspicuous mucosal conditions here. Advance the flexible endoscope into the stomach. Careful mirroring back. Inconspicuous mucosal conditions in the area of the stomach and oesophagus. Adjustment with the tonsil retractor. Then incision of the right-sided tonsil, including the areas suspected of being tumorous. Dissection laterally into the pharyngeal musculature. Careful dissection of the tumor. As far as can be assessed intraoperatively, the tumor can be completely removed. Removal of the tumor in the area of the posterior palatal arch and in the area of the base of the tongue. Careful hemostasis. Removal of several marginal samples. Clinically, the resection is performed safely in healthy tissue. If conditions are dry overall, the procedure is now completed. Final consultation with the anesthetist. Transfer of the patient to the recovery ward.
