At the beginning of the operation, the surgeon positions the patient. After induction of anesthesia, alcohol disinfection and infiltration anesthesia are performed. A zigzag incision is then made in the midline. Careful dissection through the subcutaneous tissue to the prelaryngeal muscles. This is pushed apart in the midline. Now expose the larynx from the incisura to below the cricoid cartilage. Tissue in the form of a pyramidal lobe of the thyroid gland is visible below the cricoid cartilage. However, after clamping and ligation, this piece of tissue is removed and sent for final histology. The larynx is then dissected in the midline. Sawing open with the wheel. As described above, the tumor is limited to the right vocal fold. It extends to the anterior commissure, but not beyond, and is firmly attached to the anterior part of the thyroid cartilage and cannot be moved. Careful dissection with pointed scissors and the Freer. Detachment of the tumor then also with the punch from the anterior thyroid cartilage. Therefore possible R1 resection here. Dissection then dorsally up to the arytenoid cartilage. The tumor preparation is sent for final histology. Now saw out the triangle from the thyroid cartilage where the tumor had grown in the anterior region. This is sent as the 2nd specimen for final histology. Now take representative edge samples. These are all found to be tumor-free by <CLINICIAN_NAME> from the pathology department in the frozen section. Careful hemostasis. Irrigation of the wound. Adaptation of the thyroid cartilage. Then closure of the lower triangle using muscle flaps. Subsequent insertion of a flap and adaptation of the prelaryngeal muscles in the midline. Now 2-layer wound closure. Completion of the procedure without any indication of complications.
