Before the start of the operation, repeat the procedure with the Kleinsasser tube. The tumor extends from the anterior commissure, reaching it and passing discreetly to the left onto the anterior vocal cord and posteriorly to the arytenoid. The pocket fold is reached superiorly. Overall, however, the tumor is very mobile and does not appear to infiltrate the cartilage clinically. Due to the extent of the tumor, the decision was made to perform a laser resection. The Kleinsasser tube is now used to adjust the anterior commissure. The tumor is now cut around the healthy part with the laser, including the anterior part of the left vocal fold and pocket fold. Excision is made in the anterior commissure down to the cartilage. The incision is then made caudally subglottically in the healthy area posteriorly. Separation of the cartilage from the arytenoid hump. The cartilage is preserved in any case, and the muscular structures are also preserved for the most part. Cranial and posterior resection of the pocket fold with the tumor. Here the tumor definitely does not reach the cartilage. Finally, the tumor can be cut around with the laser in toto microscopically and macroscopically in healthy tissue. Representative circular edge samples are taken. These are found to be tumor-free in the frozen section. Therefore, after extensive hemostasis with monopolar coagulation and supratupfer, the procedure is terminated. Wait for the definitive histology, then plan a follow-up endoscopy in 8 weeks.
