Supraglottic sulcus tumor: a tumor with a specific biological type. Features: The tumor invades the top of the chest above the second rib, and is mostly associated with painful symptoms such as upper limb pain and diaphragmatic paralysis, while the top of the chest cavity has an extremely complex and important vascular and nerve alignment and complex skeletal structure, so it was always considered incompletely resectable years ago and treatment was mostly based on radiotherapy. For most thoracic surgeons, surgery for supraglottic sulcus tumors is still a great challenge. Because of the special location of supraglottic tumors, most of them cannot be completely resected by the traditional postero-lateral open incision. In recent years, we have adopted a modified transsternal sternal stalk incision to solve these shortcomings. A significant proportion of national superior sulcus tumors originate from post-tuberculosis scar carcinoma, which is less malignant and has a tendency to be locally invasive but less likely to metastasize distantly. Tumor invasion of blood vessels and brachial plexus nerve is not a contraindication to surgery, and the complete resection and replacement of the invaded blood vessels can achieve quite satisfactory results after preoperative half-volume radiotherapy.
