The patient was diagnosed with squamous cell carcinoma of the right vocal fold during a panendoscopy with microlaryngoscopy <2013>. In addition, the rhinoscopy revealed a large polyp in the area of the left middle nasal passage. A CT scan showed a shadow in the area of the ethmoid bone on the left and also on the right. As the patient was symptom-free with regard to the nose, the decision was made to perform a circumscribed, findings-adapted sinus operation on the left with polypectomy and laser chordectomy on the right in the case of histologically confirmed carcinoma.
