Pharyngeal cysts are divided into nasopharyngeal cysts, oropharyngeal cysts and laryngopharyngeal cysts. Different parts of the cysts have different symptoms, mainly: nasal congestion, poor ventilation, swallowing obstacles, foreign body sensation in the throat, hoarseness and dyspnea. 1. Nasopharyngeal cysts: they appear in the nasopharynx with symptoms of nasal congestion, poor ventilation and sometimes increased nasal discharge. 2. Oropharyngeal cysts: appear in the oropharynx, may have swallowing obstruction and discomfort. 3. Laryngopharyngeal cysts, epiglottis cysts, mainly due to pharyngitis and other inflammatory stimuli, causing mucosal edema. It causes dysphagia when swallowing food, and there may be foreign body sensation in the throat. If the cyst grows on the vocal cords, it becomes a vocal cord cyst, which can cause vocal cord vocal disorders, and the vocal cords can not be closed normally, resulting in hoarseness. 4. Difficulty in breathing: as the pharyngeal cysts continue to grow, resulting in the narrowing of the airway, will gradually block the airway, causing breathing difficulties. Pharyngeal cysts should be rushed to the hospital in time and treated under the guidance of professional doctors.
