Simpson Grade I Removal of Tuberculum Sella Meningioma Through the Supraorbital Approach: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2021 May 14. Epub 2021 May 14.

Department of Neurosurgery, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

As described by Cushing1 in the chiasmatic syndrome, tuberculum sellae meningiomas induce progressive asymmetrical, incongruous visual loss, which would lead to blindness. The surgical removal of these lesions has been rewarding in regard to visual preservation, or recovery, and has passed the test of time. Optic canal extension, in one or both canals, is a consistent feature of these tumors, and removing the tumor from the optic canals is paramount in the treatment of these lesions. Read More

Simplifying Access to the Lateral Sphenoid Recess: A Modification of the Transpterygoid Approach.

Am J Rhinol Allergy 2021 Mar 24:19458924211003813. Epub 2021 Mar 24.

Head and Neck Institute, Cleveland Clinic, Cleveland, Ohio.

Background: Meningoencephaloceles originating in the lateral recess of the sphenoid sinus can be difficult to access. Historically, the endoscopic transpterygoid approach was advocated, which carries additional morbidity given the dissection of the pterygopalatine fossa (PPF) contents to provide a direct line approach to the defect. Given our increased facility with angled endoscopes and instrumentation, we now approach this region in a less invasive manner. Read More
