Introductory consultation with the anesthetist. Then advance the 0° scope through the glottic plane into the trachea. Advance the endoscope. Mucosal conditions are unremarkable on all sides up to the exit of the segmental bronchi during reflection. There were also no abnormalities in the subglottis, glottis and supraglottis. Now intubation of the patient. Inspection of the larynx. No special features in the area of the subglottis, glottis and supraglottis. Inspection of the oropharynx and oral cavity. No special features. After pulling up the soft palate, there are no special features in the nasopharynx. Inspection of the hypopharynx: There is a mucosal appearance in the area of the piriform sinus on both sides. In the area of the posterior pharyngeal wall, passing over to the right side, a papillomatous, broad-based structure can be seen above the arytenoid cartilage. This structure is most suspicious for a papilloma. Set-up of the CO2 laser and resection of this mucosal area as an excisional biopsy. Under the microscope, this papilloma is completely resected with the laser while sparing the muscles. Careful hemostasis. Dry conditions at the end of the operation. Further procedure depending on the histology. Final consultation with the anesthetist. Completion of the procedure.
