    It is typically caused by a basilar skull fracture, which presents complications such as infection. It may be diagnosed using brain scans (prompted based on initial symptoms), and by testing to see if discharge from the nose is cerebrospinal fluid.

    The pain can ultimately become disabling unless the ambient pressure is reversed. The pressure difference causes the mucosal lining of the sinuses to become swollen and submucosal bleeding follows with further difficulties ventilating the sinus, especially if the orifices are involved. Ultimately fluid or blood will fill the space.
