First, after intubation of the patient with the laser tube, insertion of a mouth guard, insertion of a size B small bore tube. Expose the tumor. This starts just in front of the arytenoid cartilage and extends to just in front of the anterior commissure. Based on the biopsies, resection of the most anterior parts of the right vocal fold, which is included in the resection. Resection forward to the cartilage. Removal of the specimen. Successive laser removal of the tumor with a safety margin of at least 3 to 4 mm on all sides. In the anterior lateral area up to cartilage level, soft tissue remains in the posterior lateral area. Resection including the anterior parts of the arytenoid cartilage. Resection also with parts of the conus elasticus. After removal of the specimen, it is marked with sutures. In addition, marginal samples from the arytenoid area from the lateral side and from the area of the anterior commissure. Marginal samples and specimen are sent to the frozen section. Here the specimen and margin samples are tumor-free. Thus R0 situation. Subsequent careful hemostasis. Absolutely hemorrhage-free site on final inspection. Tracheotomy is not necessary. Subsequent removal of the mouth guard and small irrigation tube. The procedure was completed without complications. Overall still just T1a, rather no T1b glottic carcinoma. Due to the resection down to the cartilage, the patient still receives 600 mg Clindamycin i.v. intraoperatively, which should be continued postoperatively for a total of 1 week. Follow-up MLE in 8 to 12 weeks is essential.
