Rare Mandibular Surgical Ciliated Cysts: Report of Two New Cases

The surgical ciliated cyst, also known as the “postoperative maxillary cyst” or “implantation cyst,” occurs as a result of iatrogenic implantation of respiratory epithelium into a noncontiguous surgical site after sinus surgery. It typically presents as a well-defined radiolucency in the maxilla in young adults. Histopathologically, the cyst is lined by ciliated columnar, cuboidal, or pseudostratified squamous epithelium with mucous cells. We report two rare cases of a surgical ciliated cyst located in the mandible.
