Objective:As exclusively endoscopic endonasal resection of benign orbital tumors has become more widespread,high-quality outcomes data are lacking regarding the decision of when and how to reconstruct the medial orbital wall following resection.The goal of this study was to systematically review pertinent literature to assess clinical outcomes relative to orbital reconstruction practices.Methods:Data Sources:PubMed,EMBASE,Web of Science.A systematic review of studies reporting exclusively endoscopic endonasal resections of benign orbital tumors was conducted.Articles not reporting orbital reconstruction details were excluded.Patient and tumor characteristics,operative details,and outcomes were recorded.Variables were compared usingχ^(2),Fisher’s exact,and independentt tests.Results:Of 60 patients included from 24 studies,34(56.7%)underwent orbital reconstruction following resection.The most common types of reconstruction were pedicled flaps(n=15,44.1%)and free mucosal grafts(n=11,32.4%).Rigid reconstruction was uncommon(n=3,8.8%).Performance of orbital reconstruction was associated with preoperative vision compromise(P<0.01).The tendency to forego orbital reconstruction was associated with preoperative proptosis(P<0.001),larger tumor size(P=0.001),and operative exposure of orbital fat(P<0.001)and extraocular muscle(P=0.035).There were no statistically significant differences between the reconstruction and nonreconstruction groups in terms of short-or long-term outcomes when considering all patients.In patients with intraconal tumors,however,there was a higher rate of short-term postoperative diplopia when reconstruction was foregone(P=0.041).This potential benefit of reconstruction did not persist:At an average of two years postoperatively,all patients for whom reconstruction was foregone either had improved or unchanged diplopia.Conclusion:Most outcomes assessed did not appear affected by orbital reconstruction status.This general equivalence may suggest that orbital reconstruction is not a necessity in these cases or that the decision to reconstruct was well-selected by surgeons in the reported cases included in this systematic review.
