Cysts in the right lateral wall of the pharynx may be tonsil cysts and pharyngeal mucus cysts, which can be treated conservatively or surgically. If the cyst is small, does not cause physiological abnormalities, the swelling grows slowly and does not affect physiological function, the lesion can be dynamically observed for changes and there is no need to rush to treatment. 1. Tonsil cysts: If the tonsil cysts are relatively large and affect swallowing and breathing, trigger recurrent acute episodes of chronic tonsillitis, as well as the pharynx, foreign body sensation, tingling and other symptoms are obvious, tonsillectomy can be done, and at the same time, remove the cysts. 2. Pharyngeal mucus cysts: mostly caused by the blockage of mucus gland ducts of small salivary glands in the side wall of the pharynx, such as larger cysts that cause breathing and swallowing obstacles, or the swelling grows faster and causes inflammation to form abscesses, surgical resection can be chosen for treatment. When you find the growth of cysts on the right side wall of the pharynx, you can actively seek medical treatment and follow the doctor’s instructions to standardize the diagnosis and treatment.
