Introductory consultation with the anesthetist. Then adjustment of the larynx with the size C small bore tube. This is extremely difficult. By positioning the patient appropriately, the glottic plane can be adjusted well. Using the laser, resection of the tumor in the sense of a right chordectomy. The resection ultimately extends from the posterior commissure from the tip of the arytenoid cartilage to the anterior commissure. Careful preparation in the paraglottic space. Repositioning the MLE tube and changing the MLE tube so that the anterior commissure can be exposed with the smallest MLE tube (size D). Clinically, it is clearly possible to cut around the tumor in healthy tissue, whereby large parts of the subglottic slope and the vocalis muscle are also resected. In the area of the anterior commissure, the cartilage is exposed in a circumscribed manner. As far as can be assessed intraoperatively, the tumor can be completely resected in the healthy tissue. This is made possible by frequent changes of position and massive external pressure. After resection of the tumor, a total of four marginal samples are taken, all of which are found to be tumor-free in the frozen section. Careful hemostasis. Completion of the procedure. In view of the size of the tumor, a control MLE is absolutely indicated in 6-8 weeks. Final consultation with the anesthesiologist. Transfer of the patient to the recovery ward.
