Abstract

ObjectiveTo review our experience of reconstructing the lateral and superior orbital walls after resection of sphenoid wing meningiomas. We will review the presentation and complications, examine the aesthetic results postoperatively, and compare preoperative and postoperative computed tomographic scans. To our knowledge, a comparative analysis of preoperative defect and postoperative reconstruction has not been performed.MethodsWe conducted a retrospective analysis, with a minimum of 5 months and a maximum of 9 years of follow-up in an academic multidisciplinary skull base center. Twenty-two patients were treated for sphenoid wing meningiomas by resection and reconstruction with split calvarial bone graft and, for more than half of the patients, also with free abdominal fat graft. The main outcome measures were aesthetic evaluation of patients and analysis of tumor control using computed tomographic scans, survival, and complications.ResultsA total of 24 resections were performed on 22 patients. The average follow-up was 14.6 months. All patients had meningiomas with similar preoperative presentations, and for 21 of the 22 patients aesthetic reconstruction resulted in the near symmetry of the 2 sides. All patients are currently alive, those who underwent complete resection are without recurrence, and 15 (68.2%) did not incur complications. One patient experienced a worsening of temporal wasting following radiation therapy.ConclusionReconstruction of the defect with split calvarial bone and free abdominal fat grafts affords the patient excellent aesthetic results as well as good symmetry, as demonstrated by a postoperative computed tomographic scan.
