A Shift in the Orbit: Immediate Endoscopic Reconstruction After Transnasal Orbital Tumors Resection.

Endoscopic endonasal resection of orbital lesions is a safe and common approach. Nevertheless, medial orbital wall defects following the procedure are not routinely addressed, potentially leading to diplopia and enophthalmos. In this article, the authors propose a new technique for purely endoscopic endonasal reconstruction of orbital wall defects following endoscopic endonasal resection of orbital lesions. The patient, a 43-year-old male, suffering from right exophthalmos and diplopia due to a venous malformation of the right orbit underwent endoscopic endonasal resection of the mass. Excision was followed by immediate transnasal endoscopic reconstruction with a commercially available porous polyethylene mesh (Medpor). The postoperative course was uneventful. The patient did not report any residual orbital asymmetry or diplopia. No recurrence of the venous malformation, mesh infection, or reconstruction instability was reported during the follow-up. The authors believe that this new technique could spur head and neck surgeons in strategically rethinking their approach to orbital tumors, proposing reconstruction to patients on a routine basis, and developing even more reliable and manageable solutions.
