Abstract：
UNASSIGNED: The posterior orbit is a confined space, harbouring neurovascular structures, frequently distorted by tumours. Image-guided navigation (IGN) has the potential to allow accurate localisation of these lesions and structures, reducing collateral damage whilst achieving surgical objectives.
UNASSIGNED: We assessed the feasibility, effectiveness and safety of using an electromagnetic IGN for posterior orbital tumour surgery via a comparative cohort study. Outcomes from cases performed with IGN were compared with a retrospective cohort of similar cases performed without IGN, presenting a descriptive and statistical comparative analysis.
UNASSIGNED: Both groups were similar in mean age, gender and tumour characteristics. IGN set-up and registration were consistently achieved without significant workflow disruption. In the IGN group, fewer lateral orbitotomies (6.7% IGN, 46% non-IGN), and more transcutaneous lid and transconjunctival incisions (93% IGN, 53% non-IGN) were performed (p = .009). The surgical objective was achieved in 100% of IGN cases, with no need for revision surgery (vs 23% revision surgery in non-IGN, p = .005). There was no statistically significant difference in surgical complications.
UNASSIGNED: The use of IGN was feasible and integrated into the orbital surgery workflow to achieve surgical objectives more consistently and allowed the use of minimal access approaches. Future multicentre comparative studies are needed to explore the potential of this technology further.

摘要：
■后眼眶是一个狭窄的空间，有神经血管结构，经常被肿瘤扭曲。图像引导导航（IGN）有可能准确定位这些病变和结构，减少附带损害，同时实现手术目标。
■我们评估了可行性，通过一项比较队列研究，使用电磁IGN进行后眶肿瘤手术的有效性和安全性。使用IGN的病例的结果与不使用IGN的类似病例的回顾性队列进行比较。提供描述性和统计比较分析。
■两组的平均年龄相似，性别和肿瘤特征。IGN设置和注册一致实现，没有明显的工作流程中断。在IGN组中，更少的外侧眶切除术(6.7%IGN，46%非IGN)，和更多的经皮眼睑和经结膜切口(93%IGN，进行了53%的非IGN)(p=.009)。在100％的IGN病例中实现了手术目标，不需要翻修手术(非IGN的翻修手术为23%，p=.005）。手术并发症差异无统计学意义。
■使用IGN是可行的，并将其整合到眼眶手术工作流程中，以更一致地实现手术目标，并允许使用最少的入路方法。未来需要进行多中心比较研究，以进一步探索该技术的潜力。
