Induction of anesthesia by the anesthesiology colleagues, then entry with O° optics and inspection of the larynx, which reveals an exophytic mass, the subglottic region and the trachea are clear. Then intubation and insertion with the Kleinsasser tube and advancement of the microscope. An exophytic mass was found in the region of the left vocal fold, 2/3 of the left vocal fold was affected, the anterior commissure was also affected, but the tumor did not spread to the opposite side, although it was a mass that also infiltrated the pocket fold on the left side. In addition, the left vocal fold was clinically less mobile. The laser was now switched on and laser resection with 1.5 Watt Suprapulse Continuous wave was started, initially in the area of the anterior commissure so that the right vocal fold was not affected. Release of the anterior commissure, then repositioning and resection of the tumor with the laser in the area of the pocket fold and then also in the posterior area so that the ary can be completely spared. Removal of the complete specimen. Then removal of several marginal samples, all marginal samples are free of carcinoma and also free of carcinoma in situ. This concludes the procedure. When adjusting the tumor, the bridge of the upper teeth comes loose. The bridge was already very loose beforehand and the patient was informed of this. The bridge is preserved and given to the patient at the end. Please check MLE in 8 weeks and present the patient at the dental clinic.
