Surgical ciliated cysts, also known as postoperative maxillary cysts or implantation cysts, occur mainly in the posterior maxilla after radical maxillary sinus surgery; they rarely develop in the mandible. They are thought to occur when the sinonasal epithelium is infiltrated by a surgical instrument during surgery or as a result of transplantation of bone or cartilage with respiratory epithelium attached.
We report a case in which a surgical ciliated cyst developed in the anterior part of the mandible, presumably as a result of bimaxillary orthognathic surgery and genioplasty performed 24 years earlier. We then review the few similar cases reported in the literature.
Surgical ciliated cysts in the mandible are extremely rare, but they could occur after simultaneous surgery on the maxilla and mandible, even decades later. To prevent surgical ciliated cysts in the mandible, we recommend that the surgical instruments, especially the saw blade used during bimaxillary surgery, be new or cleaned and that previously placed plates and screws be removed at an appropriate time.
外科纤毛囊肿，也称为术后上颌囊肿或植入性囊肿，主要发生在上颌窦根治术后的上颌后部；在下颌骨中很少发生。它们被认为是在手术过程中鼻窦上皮被手术器械侵入，或者是由于附着有呼吸道上皮的骨或软骨移植所致。
我们报告一例外科纤毛囊肿发生在下颌前部的病例，推测是24年前进行双颌正颌手术和颏成形术的结果。然后我们回顾了文献中报道的少数类似病例。
下颌骨中的外科纤毛囊肿极为罕见，但在上颌骨和下颌骨同时手术后甚至几十年后都可能发生。为预防下颌骨中的外科纤毛囊肿，我们建议手术器械，尤其是双颌手术中使用的锯片，应为新的或经过清洁的，并且应在适当的时候取出先前放置的钢板和螺钉。
