A pharyngeal cyst is usually an abnormal expansion of a small sac in the laryngeal chambers. Cysts in this disease grow very slowly and are common in people of all ages, but people in their 30s are more likely to develop pharyngeal cysts. Laryngeal cysts are usually caused by a bacterial infection. Other causes, such as: other bacterial infections, such as Streptococcus pneumoniae; fungal infections, and people with weakened immune systems are at greatest risk for these types of infections. Viral infections, such as varicella zoster virus and herpes simplex virus. Trauma to the throat, such as blows to the throat, or burning the throat by drinking very hot liquids, smoking especially illegal drugs such as marijuana or cocaine. Usually patients with a throat abscess will have the following clinical manifestations: severe sore throat, difficulty and pain when swallowing, difficulty breathing which may improve when leaning forward, abnormal sounding and high pitched breathing (wheezing), high temperature, irritability, low or hoarse voice, drooling. For the treatment of pharyngeal cysts, if the condition is critical, the cause should be promptly identified and tracheotomy should be performed immediately. Patients with relatively mild symptoms of the disease can be treated with some antibiotics and hormones for acute laryngitis.
