Cranial fibrous dysplasia (FD) syndrome is a benign, rare, and idiopathic skeletal disorder characterized by the replacement and expansion of medullary bone by disorganized fibro-osseous tissue. Trigeminal neuralgia (TN) is most commonly caused by vascular compression at the trigeminal nerve root entry zone. Secondary TN caused by cranial FD syndrome is extremely rare. This article reports a case of cranial FD syndrome in which the lesion resulted in posterior cranial fossa narrowing, leading to the occurrence of TN. We located the patient's foramen ovale with robotic navigation, and we effectively treated the patient's TN with balloon compression.
Keywords: foramenovale; microballoon compression; robot-guided; skull fibrous dysplasia syndrome; trigeminal neuralgia.
