Initially induction of anesthesia and transoral and tracheal intubation using a laser tube by the anesthesia colleagues and positioning of the patient by the surgeon. Adjustment of the endolaryngeal findings. This revealed a pronounced exophytic mass starting from the area of the vocal process of the left arytenoid cartilage, growing anteriorly into the anterior commissure, growing laterally into the pocket fold, thus T2 glottic laryngeal carcinoma. With good adjustability, decision to attempt transoral laser resection. Setting the laser beam to continuous mode 6 watts. The laser moves around the mass. It is then possible to remove the mass macroscopically in toto using the piecemeal technique. Three marginal samples are then taken (supraglottis, anterior commissure, vocal process). All three marginal samples were found to be tumor-free by the pathology colleague <CLINICIAN_NAME>. An R0 resection can therefore be assumed. Repeated inspection. Hemostasis using monopolar coagulation and swabs soaked in suprarenin. Dry conditions. Removal of the Kleinsasser tube. Completion of the procedure without complications. Transoral laser resection of an R0 resection of a cT2 glottic laryngeal carcinoma on the left. Please schedule follow-up MLE in 8 weeks.
