“…Endoscopy combined with CASNS could provide minimally invasive access with excellent visualization to achieve accurate reconstruction and stable fixation. 31 . Pre-bent or 3D printed patient-specific implants or 3D orbital models have also been used in combination with CASNS to improve treatment results, especially in complicated, delayed or secondary reconstruction of the orbit.…”

Purpose To evaluate the outcomes with and without aid of a computer-assisted surgical navigation system (CASNS) for treatment of unilateral orbital wall fracture (OWF). Methods Patients who came to our hospital for repairing unilateral traumatic OWF from 2014 to 2017 were included in this study. The patients were divided into the navigation group who accepted orbital wall reconstruction aided by CASNS and the conventional group. We evaluated the surgical precision in the navigation group by analyzing the difference between actual postoperative computed tomography data and preoperative virtual surgical plan through color order ratios. We also compared the duration of surgery, enophthalmos correction, restoration of orbital volumes, and improvement of clinical symptoms in both groups systemically. Quantitative data were presented as mean ± SD. Significance was determined by the two-sample t -test using SPSS Version 19.0 A p < 0.05 was considered statistically significant. Results Seventy patients with unilateral OWF were included in the study cohort. The mean difference between preoperative virtual planning and actual reconstruction outcome was (0.869 ± 0.472) mm, which means the reconstruction result could match the navigation planning accurately. The mean duration of surgery in the navigation group was shorter than it is in the control group, but not significantly. Discrepancies between the reconstructed and unaffected orbital-cavity volume and eyeball projection in the navigation group were significantly less than that in the conventional group. One patient had remnant diplopia and two patients had enophthalmos after surgery in the navigation group; two patients had postoperative diplopia and four patients had postoperative enophthalmos in the conventional group. Conclusion Compare with the conventional treatment for OWF, the use of CASNS can provide a significantly better surgical precision, greater improvements in orbital-cavity volume and eyeball projection, and better clinical results, without increasing the duration of surgery.

“…6,19,22 –25 A recent study by Chen et al combined intraoperative navigation with endoscopic assistance giving even greater intraoperative overview. 26 When using PSIs, size and thickness are variable providing solutions for difficult anatomic situations as in secondary orbital reconstruction. In addition, titanium spacers can be used for intraorbital volume adjustments (Figures 1 to 3).…”

Study Design: This study presents a case-control study of 33 patients who underwent secondary orbital reconstruction, evaluating techniques and outcome. Objective: Adequate functional and aesthetical appearance are main goals for secondary orbital reconstruction. Insufficient premorbid orbital reconstruction can result in hypoglobus, enophthalmos, and diplopia. Computer-assisted surgery and the use of patient-specific implants (PSIs) is widely described in the literature. The authors evaluate the use of selective laser-melted PSIs and hypothesize that PSIs are an excellent option for secondary orbital reconstruction. Methods: The sample was composed of 33 patients, previously treated with primary orbital reconstruction, presenting themselves with indications for secondary reconstruction (i.e. enophthalmos, diplopia, or limited eye motility). Computed tomography and/or cone beam data sets were assessed before and after secondary reconstruction comparing intraorbital volumes, infraorbital angles, and clinical symptoms. Clinical outcomes were assessed using a standardized protocol. Results: Results show a significant change in intraorbital volumes and a reduction of clinical symptoms after secondary reconstruction. Conclusions: Outcomes of this study suggest that secondary orbital reconstruction can be performed routinely using selective laser-melted PSIs and titanium spacers.

“…No tratamento primário das fraturas que envolvem as paredes orbitais, a visibilidade limitada do acesso cirúrgico padrão transconjuntival geralmente pode resultar em um posicionamento incorreto dos materiais de reconstrução (CHEN et al, 2018), o que com o manejo de procedimentos cirúrgicos por navegação, torna-se possível evitar esses erros de posicionamento a esses padrões de fraturas, assim como a redução da necessidade de reconstruções secundárias (LÜBBERS et al, 2011).…”
