The patient has a histologically (G2) confirmed squamous cell carcinoma of the left glottis with transition into the anterior commissure and the right vocal fold anteriorly as well as the ventriculus laryngeus and the subglottis on the left side. The vocal process of the arytenoid cartilage appears to be infiltrated. However, the patient vehemently rejects a laryngectomy and radiochemotherapy. For this reason, there is an indication for renewed microlaryngoscopy and an attempt at partial resection according to Leroux-Robert.
