Abstract

Background: Supraorbital craniotomy (SOC) has brought a paradigm shift in approaching anterior skull base lesions. With better understanding of relevant anatomy, the indications are being stretched from highly selected, small-to-moderate-sized tumors to large and complex anterior skull base lesions. Objective: We share our experience and discuss the nuances of surgery for large anterior skull base meningiomas using the SOC. Methods: This is a single institute study using prospectively collected retrospective data from seven cases of large anterior skull base meningiomas (>3 cm) using the SOC. We reviewed the indications, safety, and procedural complications in these cases. Results: Simpson's Grade 2 excision was achieved in all these seven cases, with faster postoperative recovery. Follow-up clinical outcome and cosmesis were satisfactory. Conclusion: SOC is a safe alternative for the standard skull base approaches in treating large anterior skull base meningiomas. The SOC can be effectively used to treat selected large anterior skull base meningiomas.
