There is a common clinical symptom of a type of disease, self-perception of blockage in the throat, tightness in the neck, sticky feeling of sticky leaves or sputum, or a small ball-like “mass” moving up and down in the pharynx, neither swallowing nor spitting out, more obvious when swallowing saliva, but eating is not prevented. First of all, to exclude hypopharyngeal or esophageal masses, it is necessary to go to the hospital for detailed examination and clear diagnosis. Second, if the mass is excluded, we can consider “pharyngeal xenophobia” pharyngeal congestion, foreign body sensation in the pharynx is called pharyngeal xenophobia in Western medicine. The pathogenesis of pharyngeal heterosensitivity is more complex. Some local factors in the pharynx, upper esophagus and surrounding tissues (including factors that were insignificant) stimulate the nerve endings of the stomach and esophagus, which are transmitted upward to the cerebral cortex, causing the sensory center to produce some abnormal sensations. People who are already depressed, mentally unstable or suffering from neurosis are even more mentally disturbed by such sensations, which aggravate the sensations. The fear of cancer, depression and mental uneasiness themselves cause excessive tension in the plant nerves and neurovascular dysfunction, which aggravate the abnormal sensations in the throat. Common causes: 1. Common ENT diseases causing pharyngeal heterosensitivity include: chronic pharyngitis (lymphatic follicle hyperplasia in the posterior pharyngeal wall), chronic nasopharyngitis (congestion in the nasopharyngeal roof or posterior wall with secretions), chronic sinusitis (purulent secretions in the posterior nostrils) posterior nostril polyps, epiglottis cysts, hyperplasia of the caudate, lymphatic tissue hyperplasia of the tongue root, etc.; 2. Related to gastroesophageal reflux; 3. The cause is unknown. Treatment: Targeted treatment according to the cause. Laryngeal cancer is one of the common malignant tumors in otorhinolaryngology and the second most common cancer of 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, postoperative speech rehabilitation of these patients is of great importance to improve their survival quality. The main methods of speech rehabilitation after total laryngectomy are artificial larynx, esophageal articulation and articulation reconstruction surgery. Du Jianqun, Department of Otolaryngology and Head and Neck Surgery, Tianjin First Central Hospital Esophageal articulation method After laryngectomy, no vocal cords can still be vocalized after training, which is also called esophageal voice. After the larynx is removed, 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. Electronic larynx 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 holes vibrates the eardrum inside the artificial larynx to produce sound. The air flow from the lung enters the esophagus or hypopharynx through this channel and impacts the mucous membrane to produce sound, which is called tracheoesophageal voice. There are two types of surgical reconstruction methods: (1) tracheoesophageal fistula. (Disadvantage: aspiration of water into the trachea is easy) (2) Tracheoesophageal puncture articulation tube implantation. (2) Tracheoesophageal puncture and implantation of a silicone hair tube. (Disadvantage: the pronunciation button needs to be replaced regularly, and the pronunciation button is more expensive).
