Tracheoscopy. No abnormalities here. Perform panendoscopy. Enter with the Kleinsasser tube and inspect the hypopharynx and larynx. No abnormalities here. Perform an oropharyngoscopy. There is a rough mass in the area of the left tonsil that extends to the soft palate as well as to the anterior and posterior palatal arch and cannot be moved. Marking of the incision margins and incision of the mucosa with the monopolar needle. Part of the soft palate on the left must be resected. Successive dissection of the tumor with removal of a small muscle margin in the depth. The anterior palatal arch must be resected completely, the posterior palatal arch partially and a small area of the base of the tongue. The specimen is thread-marked and sent to the frozen section. All edges are tumor-free in the frozen section. In the meantime, the PEG is inserted. Entering with the flexible esophagoscope and pre-mirroring into the stomach. Oesophagus and stomach unremarkable. If the diaphanoscopy is good, perform the PEG insertion using the thread pull-through method. Due to the very large wound area in the oropharynx, perform a small tracheostomy. Skin incision below the cricoid cartilage for this. Exposure of the musculature. Splitting of the musculature in the linea alba. Exposure of the thyroid gland. Undermining of the thyroid gland. Dissection of the thyroid gland. After bipolar coagulation, exposure of the anterior wall of the trachea. Entering the trachea between the second and third tracheal cartilages. Creation of a visor tracheotomy. Creation of a mucocutaneous anastomosis. Caudal and cranial insertion of an 8 mm tracheal cannula. Completion of the procedure without complication. Waiting for the final histology and planning of a neck dissection on both sides. Subsequent presentation at the tumor conference.
