After appropriate preparation, first set the endolarynx with the JA tube under the protection of the edentulous maxilla. Here you can see the slightly thickened right vocal fold, which has two whitish overlays, with the whitish overlay extending dorsally to the vocal process. Even with external pressure, the glottis on the right side is not completely visible laterally, but is covered by the supraglottis. For this reason, a strip of tissue is first resected from the supraglottis. The right vocal fold is then fully visible. It can now be seen that the changes in the vocal folds do not extend into the anterior commissure. The tumor also does not extend very far laterally on palpation. Start with laser surgical chordectomy with the CO2 laser ventrally. Here, the vocal fold is resected at a sufficient microscopic safety distance. Laterally, parts of the vocalis muscle are included in the resection. The resection extends posteriorly to the arytenoid cartilage, which is exposed at the vocal process, whereby the last section of the mucosa appears inconspicuous here. The resection is then guided caudally over the subglottic slope under visualization so that the entire resectate can then be removed in toto. Suture marking on the ventral resection margin. The resection margins are then resected with cold instruments and the removed tissue is sent as a resected specimen for frozen section histology. These are all found to be tumor-free. Careful hemostasis is then performed. After receiving the frozen section histology diagnosis, the patient was extubated without any problems and handed over to the anesthesia department. Conclusion: Transoral laser surgical chordectomy on the right side for cT1a glottic laryngeal carcinoma. As part of the tumor follow-up, a 1st control panendoscopy is recommended after 10-12 weeks
