History of multiple ablation of a carcinoma in the area of the left vocal fold. The last biopsy <2018> revealed a G3 differentiated squamous cell carcinoma in a biopsy of the left anterior vocal fold. Due to the lack of exposure of the anterior commissure, there is now an indication for a partial laryngectomy from the outside. The patient had ample opportunity to ask questions about the procedure before the operation. As part of the preoperative CT scan, cT1 cN0 glottic carcinoma on the left. Additional findings: cerebellar mass. This still needs to be clarified by magnetic resonance imaging in the interval.
