[Motor complications during Herpes zoster of the ophtalmic branch of the trigeminal nerve. Electromyographic study of 7 cases (author's transl)].

It has been recently shown that in addition to ganglia the nerve is involved during Herpes Zoster. Electromyographic investigations of the masseter muscle, were carried out on the side of the skin lesions in 7 cases of Herpes Zoster of the first trigeminal branch. In 4 cases there was a partial denervation, possibly due to a mononeuritis of the motor branch of the trigeminal nerve. It is probable that systematic electromyographic examinations may demonstrate a higher proportion of motor complications during Herpes Zoster than previously accepted.
