Traumatic ciliated cyst derived from zygomaticomaxillary fracture: Report of a case

A surgical ciliated cyst of maxilla is well known as a delayed complication of radical maxillary sinus surgery for chronic sinusitis. Recent reports have suggested that orthognatic surgery, implant-related surgery, and fracture surgery also causes a development of surgical ciliated cyst. It is documented that small segments of sinus mucosa become entrapped between the bony edges of the maxilla, which resulting in cystic degeneration of the entrapped sinus mucosa many years later. However, few papers are available that fracture individual could lead to a development of a maxillary cyst with pseudostratified columnar ciliated epithelium. Here we report a unique case of the ciliated cyst in the maxilla, supposed to be derived from the zygomaticomaxillary fracture individual conservatively treated 30 years before. The diagnostic difficulty of this lesion is also discussed.
