There is still a soybean-sized pharyngeal cyst on review after surgery, which may be a recurrence. Pharyngeal cysts arise mainly due to local inflammatory stimulation, but also due to congenital dysplasia produced. However, pharyngeal cysts grow more slowly and are often combined with fistulas and secondary infections. Theoretically, when a pharyngeal cyst is operated on, it is generally difficult for the lesion to recur if it is completely removed. If the lesion is found to be incompletely removed and there is residual cystic cavity after surgery, it will easily lead to recurrence of pharyngeal cyst after surgery, i.e. recurrence. It is recommended to observe the patient for a period of time, if the pharyngeal cyst does not increase in size or show clinical symptoms after review, the patient may not undergo the second surgery for the time being. If the pharyngeal cyst grows faster and symptoms such as dyspnea appear, secondary surgery may be needed. It is recommended that patients go to the hospital and under the guidance of the doctor, do not use drugs without authorization or delay leading to deterioration of the condition.
