[On the etiology and therapy of essential blepharospasm (author's transl)]

The etiology of essential blepharospasm is extraordinarily manifold and still not clarified in many instances. The therapeutic possibilities are as manifold and not always satisfactory. One of these surgical interventions consists in the dissection of the auriculo-temporal nerve shortly after its separation from the stem of the facial nerve. In 3 cases with particularly severe blepharospasm, a permanent therapeutic result which was satisfactory in every respect could be achieved in cooperation with an otorhinolaryngologist. For the ophthalmologist, a knowledge of the various therapeutic possibilities is of significance in order to adjust the treatment accordingly.
