SURGICAL CILIATED CYST OF THE MAXILLA: REPORT OF A RARE LATE SURGICAL COMPLICATION

Abstract

Surgical ciliated cyst (SCC) is a rare lesion supposed to arise due to the entrapment of the remnants of the maxillary sinus lining epithelium in the surgical bone wound. A 51-year-old White woman complained of painful enlargement in the right malar region for approximately 1 year. Her medical history revealed a surgical intervention after a zygomatic bone fracture 10 years earlier. Computed tomographic sections showed a hypodense unilocular image causing expansion of the maxillary sinus walls and fenestration of the orbit floor. Surgical enucleation and reconstruction of the bone defect were performed. Histopathologic examination showed a cyst with a lining that varied from cuboidal, ciliated cylindrical pseudostratified to stratified squamous epithelium with scattered mucous cells. The fibrous wall had hyaline acellular areas with a chronic inflammatory infiltrate. The diagnosis was SCC. After 1 year of follow-up, no recurrence was noted.
