Abstract：
BACKGROUND: Zygomatic implants have been proposed in literature for atrophic maxillary fixed oral rehabilitations. The aim of the present research was to evaluate, by a clinical and tomography assessment, a surgical complication of a zygomatic implant penetration to the orbit.
METHODS: A 56 year-old female patient was visited for pain and swelling in the left orbit after a zygomatic implant protocol. The orbit invasion of the zygomatic implant screw was confirmed by the CBCT scan. The patient was treated for surgical implant removal and the peri- and post-operative symptoms were assessed. No neurological complications were reported at the follow-up. The ocular motility and the visual acuity were well maintained. No purulent secretion or inflammatory evidence were reported in the post-operative healing phases.
CONCLUSIONS: The penetration of the orbit during a zygomatic implant positioning is a surgical complication that could compromise the sight and movements of the eye. In the present case report, a zygomatic implant removal resulted in an uneventful healing phase with recovery of the eye functions.

摘要：
背景：文献中已经提出了用于萎缩性上颌骨固定口腔修复的Zygomo植入物。本研究的目的是评估，通过临床和断层扫描评估，颧骨植入物穿透眼眶的手术并发症。
方法：一名56岁的女性患者，在进行骨植入治疗后，因左眶疼痛和肿胀而就诊。CBCT扫描证实了the骨植入螺钉的眼眶侵入。患者接受外科植入物移除治疗，并评估围手术期和术后症状。随访时未报告神经系统并发症。良好地保持了眼运动和视力。在术后愈合阶段，没有脓性分泌物或炎症证据的报道。
结论：颧骨植入定位过程中眼眶的穿透是一种手术并发症，可能会损害眼睛的视力和运动。在本案例报告中，骨植入物的去除导致了一个平稳的愈合阶段，恢复了眼睛的功能。
