New laryngeal reconstruction

New laryngeal reconstruction is a new technology developed in the 1980s. It was pioneered by Huang Henian of Shanghai Medical University in 1981. It is mainly used in patients with laryngeal cancer who need subtotal laryngectomy to reconstruct the three functions of larynx pronunciation, breathing and swallowing on the basis of eradication of lesions. Laryngeal reconstruction is a method pioneered by Arslan Serafini (1971) for direct anastomosis of the trachea and pharynx. The upper end of the cervical trachea replaces the larynx, which has made great progress in the reconstruction of pronunciation and respiratory function. Improved, but there are still reports of mistaken swallowing, which may lead to lung infection, and even block the airway, causing suffocation. The contradiction of pronunciation and swallowing function has not been properly resolved. The main reason is that the neck trachea is dissected Structurally it has not been able to replace the physiological function of the larynx. Therefore, the role of new laryngeal reconstruction is to create autologous cartilage, bone, muscle and nerve tissue for reconstruction.
