Description
Razan Ahmed Alawaz leads a three-author team reporting a 2026 case of chronic oculomotor nerve palsy in a teenager, traced to an old sphenoid sinus lesion. A 16-year-old boy had a long outward drift of the right eye and growing limits on eye movement from early childhood. Examination showed restriction of inward, upward, and downward gaze, a wide outward squint, and a fixed dilated pupil, matching third cranial nerve palsy. The right eyelid did not droop despite the motor deficit.
His history included a sphenoid sinus lesion treated years earlier with endoscopic surgery and partial removal. Tissue study had shown a histiocyte-rich lesion wrapped in fibrosis. MRI showed surgical changes and arrested development of that sinus, with no returning mass. It also showed fatty wasting of two eye muscles from denervation. The authors stress that sinus disease near the cavernous sinus can damage eye nerves in children.
