Summary Osteogenesis imperfecta (OI) is a bone disorder that can lead to skull base deformities such as basilar invagination, which can cause compression of cranial nerves, including the trigeminal nerve. Trigeminal neuralgia in such cases remains a challenge, given distorted anatomy and deformities. We present an alternative option, consisting in cannulation of the foramen ovale and classical percutaneous treatment. Percutaneous balloon microcompression was performed in a 28 year-old woman with OI and severe trigeminal neuralgia using computed tomography (CT) and radiographic-guided cannulation of the Gasserian ganglion without neuronavigation or stereotactic devices. The patient developed hypoesthesia on the left V1, V2 and V3 segments with good pain control. This alternative technique with a CT-guided puncture, using angiosuite without the need of any Mayfield clamp, neuronavigation systems, frame or frameless stereotactic devices can be a useful, safe and efficient alternative for patients with trigeminal neuralgia with other bone deforming diseases that severely affect the skull base.
