A Case in Which Infection Was Recognized after Le Fort Ⅰ Type Osteotomy Using an Absorbable Plate and Developed into a Surgical Ciliated Cyst

Abstract

We report a case of a surgical ciliated cyst that developed after Le Fort Ⅰ osteotomy with an absorbable plate. A 35-year-old woman who underwent a Le Fort Ⅰ osteotomy in 2017 was referred to our hospital because of swelling and pain at the bottom of the left nasal cavity. Computed tomography revealed a single-chamber transmission image on the inferior margin of the piriform aperture. The patient was treated surgically under general anesthesia. The thin bone wall between the cystic cavity and the maxilla was removed, and thick fibrous tissue was observed. The postoperative course was uneventful, and there were no signs of recurrence. Histopathological findings revealed a surgical ciliated cyst lined by multi-lineage hairy epithelium and squamous epithelium.
