Transorbital and transnasal endoscopic repair of a meningoencephalocele.

A 71-year-old female with a history of thyroid eye disease (TED) presented for evaluation of a skull base mass noted on neuroimaging. She had previously undergone bilateral orbital decompressions and strabismus surgery and had no neurologic symptoms. Successful resection of the menigoencephalocele and repair of the skull base defect was performed through a combined transnasal endoscopic and transorbital approach, obviating the need for craniotomy.
