Abstract

Intracranial aneurysms pose a significant clinical challenge for cerebrovascular and endovascular neurosurgeons both in treatment decision-making and in the technical aspects. The most important question is whether the aneurysm has ruptured, thereby necessitating urgent treatment. In the unruptured ophthalmic artery aneurysm case with vision loss, the decision to treat rests on understanding the risk of hemorrhage, the success in addressing neurological deficits, and the morbidity of any potential treatment. Computed tomography angiography, conventional angiography, and magnetic resonance imaging are critical and complementary in the diagnosis and management of ophthalmic artery aneurysms, which have also been termed paraclinoid or junctional aneurysms. Due to technological advances, multiple treatment methods are possible, including surgical clipping, endovascular coiling, and flow diversion. Flow diversion is emerging as an effective, less invasive technique with good vision outcomes. This chapter discusses the data behind decision-making, reviews the surgical technique of flow diversion, and emphasizes important aspects of perioperative management.

Abstract

Background Ineffective closure of complex skull base approaches leads to wound complications and cerebrospinal fluid (CSF) leak. This can result in protracted hospital stays, additional procedures, delayed postoperative recovery, and increased cost of care. Removal of large middle fossa-infratemporal fossa tumors are particularly problematic as they result in a large dead space with gravity-facilitated CSF leakage into the cavity. In this report we describe the use of a novel technique, the “inverted gull wing” titanium mesh reconstruction. Methods Attempts to address this problem have focused primarily on closure and the use of myocutaneous flaps. Patients who have had multiple prior treatments are often afflicted with significant tissue attenuation that preclude dural closure or the use of local flaps. Although vascularized free flaps are an effective option in this scenario, they can add significant operative time and often yield suboptimal cosmetic results. We describe the use of the inverted gull wing titanium mesh reconstruction in the closure of 2 patients who underwent complex transzygomatic infratemporal fossa approaches for tumor with dural and sinonasal transgression. Results Postoperatively, there were no pseudomeningoceles, CSF leaks, or technique-related morbidities. Conclusions The inverted gull wing technique represents a simple, fast, and effective closure for complex transzygomatic infratemporal fossa approaches.
