Surgical Ciliated Cysts May Mimic Radicular Cysts or Residual Cysts of Maxilla: Report of 3 Cases

Abstract

Surgical ciliated cysts, or postoperative maxillary cysts, are benign cystic lesions induced after a surgical procedure in the maxillofacial area. It is a cystic lesion in the maxillary region that develops after radical sinus surgery to treat maxillary sinusitis. It is frequently reported in he Japanese literature, and most cases are related to revious Caldwell-Luc surgeries to treat maxillary sinustis. There are case reports of surgical ciliated cysts that eveloped after midface and bimaxillary orthognathic urgery, alveolar bone grafting, and maxillofacial trauma. It is believed that some cells of the respiratory ining are trapped during a surgical procedure or rauma. Subsequent cystic change of the trapped lining nd enlargement of the cyst from the osmotic difference ause destruction of adjacent bone and structures. As he cyst expands, it may affect the adjacent teeth. The linical scenario may be identical to a radicular cyst if a nonvital” tooth is involved. We present 3 cases of surgical ciliated cysts where the atients had previously undergone maxillary sinus sureries and later presented with cystic lesions in the axillary region similar to radicular cysts or residual ysts.
