Cisto ciliado pós-cirúrgico: relato de caso em dois brasileiros e revisão de literatura

Abstract

The postsurgical ciliated cyst (PSCC) is a benign cyst, considered a locally aggressive lesion and related to a late complication of sinus surgery. Clinically, it can present as expansion of the vestibular or palatine corticals, pain and swelling in the adjacent facial region. Most cases occur in the posterior region of the maxilla and the diagnosis is challenging, as the clinical and radiographic features may resemble other pathologies. Treatment consists of enucleation or curettage of the cyst, with a good prognosis and rare recurrences. The aim of the study was to report two cases of PSCC in Brazilian patients, both in the sixth decade of life, edentulous, asymptomatic, with a history of trauma in the region of the maxillary zygomatic suture and traumatic tooth extraction, who later presented cystic lesions in the same region. A literature review of PSCC cases was performed taking into account the patient's age, sex, site of involvement, previous surgical history, clinical presentation, time between surgery and diagnosis, treatment, recurrence and follow-up, in order to compare the findings of cases with existing reports in the literature. According to the literature review, the youngest patient was 17 years old and the oldest 76 years old, the time between surgery and diagnosis ranged from 2 to 56 years, Le Fort I osteotomy was the most cited as a surgical history and enucleation was the most used treatment approach in case reports. Thus, it is important to carry out a detailed anamnesis and previous knowledge to include PSCC as a diagnostic hypothesis, especially in cases with a history of maxillary surgery.
