Under general anesthesia, we removed the osteotomy fixation plates and excised the lesion.Histopathological examination revealed a cyst comprising cellular fibrous connective tissue, mainly lined by stratified squamous epithelium; however, the regions of focal pseudostratified columnar and ciliated epithelium were also present. Surgical ciliated cyst was diagnosed on the basis of histopathological, clinical, and radiographical findings.Altho...
