Laryngeal cancer is one of the common malignant tumors in otorhinolaryngology, and is the second most common cancer of the respiratory tract after lung cancer, and the incidence of laryngeal cancer has been increasing in recent decade. At present, the treatment of laryngeal cancer is mainly based on surgery, and total laryngectomy is still one of the main means to treat advanced laryngeal cancer. Patients with laryngeal cancer who undergo total laryngectomy will definitely lose their speech function. After total laryngectomy, laryngeal cancer patients lose their articulation function and cannot speak, which affects social communication and causes significant mental trauma and inconvenience to patients’ life. Therefore, the postoperative speech rehabilitation of these patients is very important to improve their quality of life. The main methods of postoperative speech rehabilitation after total laryngectomy are artificial larynx, esophageal articulation and articulation reconstruction surgery. Esophageal articulation method After total laryngectomy, the patient can still vocalize after training, which is also called esophageal voice. After laryngectomy, the patient swallows the air into the esophagus and stomach through the tongue, and then burps to squeeze out the air and make the esophagus and pharynx vibrate to produce sound, and finally form speech. Esophageal articulation is the most economical and effective articulation method, without further surgery, non-invasive, without auxiliary tools, easier to master, better tone, close to the normal larynx sound, and accepted by most patients. The electronic larynx uses a battery to vibrate the air in the larynx as the source of vocal power. There is no need to worry about the source of airflow or the volume of air in this method. Simply place the electric larynx in the proper position, turn on the electronic larynx, and match the mouth shape and tongue movement. The initial learning can all pronounce the voice, but the placement of the larynx, the opening and closing of the button, and the movement of the mouth and tongue need to be practiced diligently. However, the pronunciation tone is single. Pneumatic artificial larynx Pneumatic artificial larynx is one of the tools for laryngectomees to revive their voice. The air coming out through the air hole vibrates the eardrum inside the artificial larynx to produce sound. Voice reconstruction (articulation button installation) is a surgical method to form a channel between the trachea and esophagus, through which the air flow from the lungs enters the esophagus or hypopharyngeal cavity, impacting the mucous membrane and producing sound. Surgical reconstruction methods are divided into two categories: (1) tracheoesophageal fistula (2) tracheoesophageal puncture articulatory tube implantation. The tracheoesophagus is punctured between the tracheoesophagus and a silicone hair tube is implanted.
