Dear All
I would appreciate some help with a young man with recurrent 6th nerve palsies that don't quite fit the paradigm reported for benign recurrent 6th nerve palsies:
15 yo male without prior history
2022 - presented with right abducens paresis without any cause apparent on extensive investigation. Resolved over 2 months
2025 - when he developed episodic right abduction palsy, preceded by rhinitis, occurring daily for several hours without provocation. No persistence of rhinos after resolution of rhinitis.
2026 - significant reduction in frequency, now monthly and only lasts about 1 hour, otherwise no change in each event symptomatically.
Repeated investigation, including fine cuts through orbits in axial, coronal and oblique planes, does show any pathology. Full autoimmune and metabolic screens are normal.
Any suggestions or comments are welcome.
Kind regards

We have successfully done many similar cases by an extended lateral orbitotomy to the superior orbital fissure and middle cranial fossa.
An optional, but less desirable approach is an endoscopic transnasal orbital apex decompression to decompress the optic nerve, but with no tumor excision.
