Endoscopic slide-in orbital wall reconstruction for isolated medial blowout fractures.

ABSTRACT:

Background

This study evaluated the efficacy of the endoscopic medial orbital wall repair by comparing it with the conventional transcaruncular method. This surgical approach differs from the established endoscopic technique in that we push the mesh inside the orbit rather than placing it over the defect.

Methods

We retrospectively reviewed 40 patients with isolated medial orbital blowout fractures who underwent medial orbital wall reconstruction. Twenty-six patients underwent endoscopic repair, and 14 patients underwent external repair. All patients had preoperative computed tomography scans taken to determine the defect size. Pre- and postoperative exophthalmometry, operation time, the existence of diplopia, and pain were evaluated and compared between the two methods. We present a case showing our procedure.

Results

The operation time was significantly shorter in the endoscopic group (44.7 minutes vs. 73.9 minutes, p= 0.035). The preoperative defect size, enophthalmos correction rate, and pain did not significantly differ between the two groups. All patients with preoperative diplopia, eyeball movement limitation, or enophthalmos had their symptoms resolved, except for one patient who had preexisting strabismus.

Conclusion

This study demonstrates that endoscopic medial orbital wall repair is not inferior to the transcaruncular method. The endoscopic approach seems to reduce the operation time, probably because the dissection process is shorter, and no wound repair is needed. Compared to the previous endoscopic method, our method is not complicated, and is more physiological. Larger scale studies should be performed for validation.

Project description:BackgroundLittle attention has been paid to combined orbital floor and medial wall fractures with the involvement of the inferomedial orbital strut. Managing this particular fracture can prove challenging. However, various innovative techniques have been introduced to assist with the process. Our study focuses on sharing our approach to orbital wall reconstruction using navigation guidance and titanium-reinforced porous polyethylene plates, specifically cases involving the inferomedial orbital strut. We believe that implementing a navigation system can effectively lead surgeons to the fracture site with utmost safety. Also, we hypothesized that this navigation system is beneficial to use singe fan titanium-reinforced porous polyethylene plates with orbital wall fractures involving IOS while minimizing possible complications.MethodsWe retrospectively reviewed 131 patients with medial orbital wall and orbital floor fractures with or without combined other facial bone fractures who underwent orbital wall reconstruction by a single surgeon from May 2021 to May 2023. Amongst, we identified fourteen orbital wall fractures involving the inferomedial orbital strut. We used a subciliary incision as the only approach method for performing titanium-reinforced porous polyethylene plates for navigation-guided orbital wall reconstruction. Patients were followed up for at least three months.ResultsAll cases were effectively resolved using titanium-reinforced porous polyethylene plates. There were no complications during the patient's complete recovery, confirmed clinically and radiologically. Based on the serial CT results, it was discovered that implanted titanium-reinforced porous polyethylene plates successfully covered the defect.ConclusionBased on our retrospective analysis, it has been determined that among the 131 recorded cases of orbital fractures, 14 of them (or 10.7%) involved the inferomedial orbital strut. Navigation-guided reduction using titanium-reinforced porous polyethylene (TR-PPE) plates can lead to predictable, reliable, and excellent outcomes for treating orbital fractures involving the inferomedial orbital strut without complications.

Project description:OBJECTIVES: To compare the surgical outcomes of inferomedial wall orbital decompression (IM-OD) and balanced medial plus lateral wall orbital decompression (ML-OD) in patients with inactive Graves’ orbitopathy (GO) with regard to exophthalmos reduction and ocular motility abnormalities. METHODS: Forty-two patients with inactive GO eligible for OD were randomly assigned to either the IM-OD or ML-OD groups. Pre and postoperative evaluations included Hertel exophthalmometry, sensory, and motor extraocular motility assessment, standardized photographs in the nine gaze positions, and computed tomography (CT) of the orbits. ClinicalTrials.gov: NCT03278964. RESULTS: Exophthalmometry reduction was statistically significant in both groups (p<0.001), but was greater in the ML-OD group (p=0.010). New-onset esotropia occurred in 11.1% and 23.5% of patients who underwent IM-OD and ML-OD, respectively, with no statistically significant difference in the frequency of pre and postoperative strabismus in either group. The mean increase in preoperative esotropia was 24±6.9 and 12±8.8 prism diopters in patients who underwent IM-OD and ML-OD, respectively. In the IM-OD group, abduction and elevation worsened at the first (p<0.05) and third (p<0.05) postoperative visits but were restored at 6 months. The versions did not change postoperatively with ML-OD. The preoperative CT-measured medial rectus muscle area predicted new-onset strabismus (p=0.023). Significant postoperative medial rectus muscle enlargement occurred in both groups (p<0.001). Restriction in elevation and abduction was significantly associated with enlarged inferior (p=0.007) and medial rectus muscle areas (p=0.002). CONCLUSIONS: IM-OD is as safe as ML-OD with regard to new-onset strabismus, and represents a good alternative for patients who do not require significant exophthalmos reduction. ML-OD offers greater exophthalmos reduction and smoother postoperative recovery. Patients with preoperative enlarged medial rectus muscle on CT are at risk for new-onset esotropia, and preoperative esotropia is likely to increase after OD.
