How does a surgeon remove a maxillary sinus cyst?

Often unnecessary.: most maxillary sinus cysts are benign and are only found on routine xray examination. They are usually mucous in origin and rarely is the removal recommended. If recommended the procedure involves an incision in the muccobuccal fold area and an entry into the sinus is made with a drill. The cyst is curetted-incision is closed. Minor if any discomfort. An office procedure.
