Symptomatic Arnold-Chiari Malformation and Cranial Nerve Dysfunction: a Case Study of Applied Kinesiology Cranial Evaluation and Treatment

A, B, The frontal bone. Frontal cranial faults may affect the shape of the orbital cavity, the angulation of the orbital fissures, and the tension upon the nerves and vessels passing into and out of the eyes. Under these conditions, the cranial nerves may be subject to undesirable mechanical influences of various kinds including compression, stretch, angulation, torsion, edema, and many others.

The sphenoid bone provides several important foramina for eye function. The optic canal through which cranial nerve II passes is vulnerable to disturbance when the sphenoid is shifted by the overlying frontal bone. The optic chiasm is created by the superior orbital fissure that lies between the greater and lesser wings of the sphenoid. Cranial nerves III, IV, and VI pass through this mobile opening, as well as the ophthalmic division of cranial nerve V, the frontal nerve, the lacrimal nerve, and the nasociliary nerves.
