First induction of anesthesia by the anesthesiologist, intubation using a laser tube, followed by entry with a small bore tube and inspection of the hypopharynx and larynx. An exophytic mass is seen in the area of the aryepiglottic fold on the right and at the piriform sinus entrance on the right. The mass is filmed. Then attempt to insert a spreading laryngoscope. This is particularly difficult. Call in <CLINICIAN_NAME>, who is able to adjust the tumor with difficulty. Perform laser resection, starting on the medial side. Successive resection of the tumor with a safety margin so that the tumor is safely removed from the healthy tissue. Removal of several marginal samples. All R0 in the frozen section. At the end, insertion of supratupers and hemostasis using monopolar coagulation. No bleeding. Glottis not affected and free, therefore no tracheostomy performed and no PEG inserted. Sterile washing and draping for neck dissection on the right side. After consultation with <CLINICIAN_NAME>, in the case of cN0 and small tumor extension, only neck dissection on the right side. Incision of a skin fold for this. Dissection of the platysma. Dissection of the platysma cranially. Exposure of the sternocleidomastoid muscle. Exposure of the omohyoid muscle. Exposure of the submandibular gland. Exposure of the cervical vascular sheath. Dissection of the internal jugular vein. Dissection of the facial vein. Exposure of the hypoglossal nerve. Exposure of the accessorius nerve. Dissection of the plexus branches II a to IV and dissection of the neck levels II a to IV, while sparing the plexus branches. The neck levels are sent in individually. The patient is a study patient in the <STUDY_NAME> study. Please present urgently at the tumor conference. If adjuvant therapy is necessary, this must be carried out in <LOCATION>.
