The pain, which was centered in the left hyoid region, had started insidiously a few months earlier. He had no history of dysphonia, dysphagia, difficulty with breathing, or earache. He had stopped smoking 20 years earlier. Microlaryngoscopy with the patient under general anesthesia revealed a 1×1-cm smooth mass in the left arytenoid region.
