Surgical ciliated cysts (SCC) are rare entities that were first described in the Japanese literature after treatment for chronic maxillary sinusitis. Classically associated with surgery to the maxillary sinus, they have also been reported in association with orthognathic surgery, bone grafting, and trauma. These lesions can develop from a few months up to several years after the surgical procedure. The authors report 2 new cases of SCC after a LeFort I osteotomy for class III dentofacial deformity correction. One of them presented with bilateral lesions and suffered from a recurrence after 5 years, 2 rare events associated with SCC.A review of the literature of the past 5 years was undertaken, in order to ascertain the reported time of follow-up and recurrence. A PubMed search retrieved a total of 15 articles with 17 cases reported. Nine cases were associated with orthognathic surgery, 4 with Caldwell-Luc procedures, 2 with sinus lift and 2 with trauma. The mean follow-up after removal of the SCC was of 8.6 months. Four cases did not specify the follow up time; 1 case was lost to follow-up. No relapses were reported.Like what happens with the primary lesion, a recurrence can take place several years after removal. It is the authors' opinion that adequate long-term follow-up must be granted for a timely diagnosis and treatment of relapsed SCC.
外科纤毛性囊肿（SCC）是一种罕见的疾病实体，首次在日本文献中描述是在治疗慢性上颌窦炎之后。它们通常与上颌窦手术相关，但也有报道与正颌手术、骨移植和创伤有关。这些病变可在上颌窦手术后数月至数年发生。作者报告了 2 例新的 SCC 病例，这些病例均在接受 LeFort I 截骨术治疗 III 类牙颌面畸形矫正后发生。其中 1 例出现双侧病变，5 年后复发，这是 SCC 两种罕见的并发症。作者对过去 5 年的文献进行了回顾，以确定报道的随访时间和复发时间。通过 PubMed 检索共获得了 15 篇文章，其中报道了 17 例病例。9 例与正颌手术相关，4 例与 Caldwell-Luc 手术相关，2 例与鼻窦提升术相关，2 例与创伤相关。SCC 切除后的平均随访时间为 8.6 个月。4 例未具体说明随访时间；1 例失访。无复发报告。与原发性病变一样，复发可能在切除后数年发生。作者认为，对于复发的 SCC，必须进行充分的长期随访，以便及时诊断和治疗。
