Transorbital Debulking of Sphenoid Wing Meningioma

Abstract

Objective: To describe the clinical features and outcomes of patients who underwent transorbital debulking of sphenoid wing meningioma.

Methods: Patients with a diagnosis of sphenoid wing meningioma who underwent transorbital debulking were included in this series. Preoperative and postoperative symptoms and examination findings, including best corrected visual acuity (BCVA) and proptosis were extracted from patient charts. All imaging studies, records of additional surgical and medical management, and complications of surgery were collated.

Results: Eight patients were included. The most common symptoms at presentation were blurred vision (6/8) and proptosis (6/8). The most common clinical findings at presentation were decreased visual acuity and proptosis. Mean BCVA preoperatively was 0.93 in logMARunits andmeanrelative proptosis preoperatively was 4.88 mm. All patients underwent orbitotomy with or without bone flap with decompression of hyperostotic bone and subtotal resection of soft tissue mass. Mean follow-up time was 14months. Five of eight patients experienced postoperative improvement in BCVA, for mean change of 0.32. All patients demonstrated reduction in proptosis postoperatively with a mean reduction of 3.63 mm.

Conclusions: Sphenoid wing meningioma can present with decreased visual acuity and/or proptosis. It is possible to address both of these problems in selected patients with transorbital debulking, an approach that avoids the aesthetic and functional consequences of craniotomy. The aim of this technique is not surgical cure, but rather improvement in vision and disfigurement.
