First, after alcohol disinfection, local anesthesia is applied. Skin incision. Subcutaneous preparation in depth. Median splitting of the infrahyoid musculature. Exposure of the thyroid cartilage. Push the perichondrium from the left side over to the right. Then left paramedian splitting of the thyroid cartilage. Entering the larynx. Starting from the supraglottic side, the left vocal fold is first completely incised, also towards the subglottic side and partially released. The thyroid cartilage is then also cut through on the right, so that a V-shaped section of thyroid cartilage remains on the complete resection. Here too, the soft tissue is pushed away from the inner wall of the thyroid cartilage. The tumor is then cut around successively, starting from the supraglottic area; the left tumor was only in the area of the left vocal fold, approximately up to the middle third. On the right side, the vocal fold tumor on the vocal fold extends to just before the vocal process; it also extends slightly into the morgue sinus and is completely cut around here. The specimen is thread-marked for final histology with a short/short thread mark for the vocal fold at the right rear and a long/long thread mark for the subglottic anterior commissure. Subsequent resections are then successively made in the supraglottic region and in the morgue sinus on the right and left. These are also sent for final histology. Circular margin samples are then taken. These are all tumor-free, with only minor dysplasia in the right supraglottic region, which is not resected further. Finally, careful hemostasis. Insertion of a Keel. Multi-layer wound closure and insertion of a flap. Completion of the procedure.
