First of all, after intubation by anesthesia and placement of a laser tube, insert a mouth guard and insert a size C small bore tube. Adjustment of the tumor, which is slightly difficult. In the end, however, the tumor can be adjusted well. The tumor is then cut around on all sides with a safety margin of 3-4 mm. Resection extends to the front of the cartilage, whereby all tissue is also resected. After dorsal resection up to the arytenoid cartilage. Laterally, resection of the entire vocal fold or parts of the paraglottic musculature. After removal of the tumor, which is sent for final diagnosis, removal of marginal samples. Basal, subglottic, supraglottic, anterior from the anterior commissure and posterior from the arytenoid region. Here, all tumor margin samples are free of carcinoma in the frozen section. Subsequent careful hemostasis. End the procedure with an absolutely hemorrhage-free site. Discuss the procedure again after receiving the final histology. In any case with R0 resection, also in the final findings, follow-up endoscopy in 8-12 weeks.
