Abstract:
Background:Orbital medial wall fractures, which are more common than inferior wall fractures, have traditionally been difficult to diagnose with conventional radiography. As the fracture extends deep into the bony orbit, accurately visualizing internal structures becomes challenging, increasing the risk of optic nerve compression. In a previous study, the author introduced a technique for treating medial orbital wall fractures using a combined transethmoidal and transcaruncular approach. In this study, the authors hypothesized that the use of surgical navigation could enhance precision, safety, and anatomical reconstruction in this approach and employed navigation during surgery for medial orbital wall fractures and evaluated whether it improved postoperative functional and anatomical outcomes while minimizing complications.
Methods:From September 2021 to November 2023, 48 patients with isolated medial wall fractures underwent surgical treatment using a combined transcaruncular approach and transethmoidal packing to repair the orbital fracture. Of these patients, 23 underwent surgery with the use of intraoperative navigation, while the other 25 did not. Intraoperative navigation was employed to facilitate precise fracture reduction and reduce the risk of optic nerve injury. The outcomes were compared by dividing the patients into two groups. Preoperative and postoperative assessments included ophthalmologic evaluations, Hertel exophthalmometry, and computed tomography-based orbital volume measurements.
Results:The surgical approach with intraoperative navigation was successfully performed in all patients. Postoperative outcomes showed full recovery without residual symptoms or complications. Orbital volume measurements indicated a significant reduction in the preoperative orbital volume ratio from 109.03% to 104.80% postoperatively (p< 0.001). However, changes in the Hertel scale were not statistically significant (p = 0.086).
Conclusion:The integration of intraoperative navigation in medial orbital wall fracture surgery enhances the precision of medial orbital wall restoration and minimizes postoperative complications, supporting its use in the surgical management of medial orbital fractures.
