Surgical Ciliated Cyst of the Posterior Maxilla in an Old Male, Mimicking Residual Cyst or Odontogenic Keratocyst: A Case Report

Abstract

Surgical ciliated cysts of the maxilla arise from respiratory epithelium that lodges in the maxilla after radical maxillary or sinus surgery. This case report was conducted in 2020 in Mashhad Dental School, Mashhad University of Medical Science, Mashhad, Iran. We present here an unusual case of surgical ciliated cyst of a 73-year-old adult male patient with a history of nasal polyp surgery 40 years ago. Early diagnosis due to CBCT and Clinical examination was a residual cyst or OKC (odontogenic keratocyst). The histopathology result of this lesion surprised us after the excisional biopsy and enucleation. The clinical examinations and radiographs of the jaw lesions may lead the maxillofacial surgeons to misdiagnosis and mistreatment. Therefore, it is obligatory to notice all aspects of these lesions carefully.
