For patients with trigeminal neuralgia who do not respond to medication and for whom surgical approaches are too risky, percutaneous procedures targeting the trigeminal ganglion are the current standard treatment. Percutaneous procedures are performed via the transoval approach under radiologic guidance. Identification of the foramen ovale (FO) under fluoroscopic guidance is an important part of determining the success or failure of the procedures. ⋯ Trigeminal neuralgia, foramen ovale, trigeminal ganglion, 3-dimensional (3D) facial computed tomography (CT) scans.

The incidence of intervertebral disc (IVD) degeneration has increased in recent years. A simple, reliable, and reproducible animal model is critical for understanding the underlying mechanisms of IVD degeneration. The caudal discs of rats have been proposed as a common puncture model in which to induce IVD degeneration. However, there is still no consensus on the size of needle to be used. ⋯ Low back pain, degenerative intervertebral disc, animal model, puncture needle, rat model, optimal choice.
