The aim of this study is to evaluate the peripheral nerves in diabetes mellitus with or without peripheral facial paralysis (PFP). A total of 49 diabetic patients with PFP within the last year (23 females, mean age 60.3 +/- 9.3), and 83 diabetic patients without PFP (41 females, mean age 59.5 +/- 9.9) were enrolled. The neurological examination, eye-blinking response, needle EMG and electrophysiological parameters of peripheral nerves were evaluated. The neuropathic pain, other positive and negative sensory symptoms were statistically more frequent in controls than the PFP group, while no difference was noted in total neuropathy score. Sural sensorial nerve action potential amplitudes were same in both groups. but median nerve amplitudes were significantly lower in the PFP group. It is suggested that PFP is not a part of multifocal neuropathy in diabetes mellitus. However. at least some parts of the nerve conduction studies were involved, focal neuropathies were more frequent while sensory neuropathies with small nerve fiber involvement were less frequent in diabetes patients with PFP.
