Laryngeal cancer is one of the common malignant tumors of the head and neck, and its incidence rate takes the first place among head and neck malignant tumors in the north. As we all know, larynx is the vocal organ of human body, which is connected with oropharynx and trachea, and it is the important gate of respiratory tract at the beginning of trachea, and it also has the important function of assisting swallowing. Therefore, tumors occurring in the larynx and the corresponding surgery will definitely involve these functions of the larynx. Whether and how to pronounce after laryngeal cancer surgery is one of the main concerns of patients. The surgical treatment for laryngeal cancer depends on the classification of the laryngeal tumor (i.e., the size of the tumor, the involved parts and scope, etc.), and clinically there are partial laryngectomy and total laryngectomy. Total laryngectomy, as the name implies, is the removal of the entire laryngeal body, then these functions of the larynx are lost, and the patient cannot pronounce and breathe through the mouth and nose, so the patient has to breathe through the tracheostomy in front of the neck for the rest of his life. However, in recent years, with our research on the anatomy of the larynx and the function of articulation, we have also realized the problem of articulation in patients after total laryngectomy. The principle is to use the diastolic function of the esophagus, which is a muscular organ, to inhale the pharyngeal air into the esophagus and make it expand passively to form an air reservoir, then use the esophagus to contract to make the gas in the air reservoir expel and vibrate the mucous membrane to make sound, which is the esophageal sound. Then, with the coordinated action of the conduction and resonance organs, the esophageal language is formed. Physiologically, esophageal speech does not require any instruments, is economical and simple, and avoids the trouble and pain of surgery once and for all. However, its shortcomings are: low pitch, short voice duration and long practice time. Patients after total laryngectomy can join Beijing laryngeal-free association for practice. Tracheo-esophageal vocalization: This includes tracheo-esophageal fistula and tracheo-esophageal articulatory tube implantation. The former uses autologous vein, hypopharyngeal mucosa, tracheal mucosa, esophageal mucosa and skin of the neck to form a channel between tracheoesophagus, which has a better vocal effect, long vocal time, coherent speech and does not require special training. The latter is done by puncturing the tracheoesophageal space and implanting the articulatory tube, which can be done in one or two stages. Electronic larynx – pneumatic artificial larynx: including mechanical larynx and electronic larynx. The former is the pneumatic artificial larynx, commonly known as the trumpet. When vocalizing, the catheter is inserted into the mouth, and the tracheostomy is covered with a cup, and the air flow is vocalized through the vibration chamber of the artificial larynx, and speech is formed through the oronasal resonance and the constructive airway. The latter uses electronic components to oscillate to produce frequency pulse wave currents, which are transformed into acoustic energy through a high-power amplifier transducer to make the generating membrane emit sound. In conclusion, the artificial larynx is practical and convenient, but the vocalization is monotonous.
