Retro-orbital pain and TMD (TMJ) explained anatomically in this article.

A mechanism for retro-orbital pain and TMD is presented in this anatomical dissection of the the temporal branch of the zygomatic nerve passing through an accessory canal in the sphenozygomatic suture. This anatomical placement of the nerve would allow temporal muscle tension to cause nerve irritation and retro-orbital pain. Utilization of a diagnostic neuromuscular orthotic could
