most common cranial mononeuropathy in diabetics affects

Diabetic Mononeuropathies or Multiple Mononeuropathies The most common mononeuropathies are median neuropathy at the wrist and ulnar neuropathy at the elbow, but peroneal neuropathy at the fibular head, and sciatic, lateral femoral, cutaneous, or cranial neuropathies also occur . In regard to cranial mononeuropathies, seventh nerve palsies are relatively common but may have other, nondiabetic etiologies. In diabetics, a third nerve palsy is most common, followed by sixth nerve, and, less frequently, fouh nerve palsies. Diabetic third nerve palsies are characteristically pupil-sparing.
