The fracture fragment is located inside the skull, so it is risky to change the position of the fracture fragment and involves brain tissue, so neurosurgery denies the possibility of surgery. However, the fracture fragment can be removed from the wall of the pterygoid sinus through transnasal endoscopy, which can also play the role of expanding the space to relieve the compression of the articular nerve and does not involve the brain, which obviously reduces the risk of surgery.
