Trans-Eyebrow Mini-Orbitozygomatic Pterional Approach for Minimally Invasive Skull Base Surgery

Abstract

Surgical treatment of skull base pathologies remains one of the most challenging tasks to neurosurgeons. Advances in neuroimaging as well as the evolution of modern techniques and neurosurgical equipment have paved the way for a more precise diagnosis, a better selection of the surgical approach and have prompted the adaptation of minimally invasive concepts to different aspects of modern neurosurgical practice. The trans-eyebrow mini orbitozygomatic pterional approach is a tailored approach that provides multiple avenues to the target, minimizing retraction of the brain and affords better exposure of the pathology. It was performed on 16 patients with frontobasal or suprasellar tumors. The post-operative clinical outcome was excellent with smooth and fast recovery as well as satisfactory cosmetic results. It should be considered as part of the armamentarium to manage skull base lesions when indicated and not to replace other well recognized skull base approaches.
