[Operations on the peripheral nervous system in the treatment of spasmodic torticollis].

The aetiopathogenesis of spasmodic torticollis has not yet been explained. The problem of surgical treatment selection is also at issue. The authors present own observations in 5 cases treated by operations on the peripheral nervous system. In 3 cases a very good therapeutic results was obtained, in 2 cases the results was not satisfactory. A characteristic fact was appearance of ultimate improvement only several months after the operation, similarly as it is observed after stereotactic operations. In the light of own observations and a survey of the literature the authors reach the conclusion that operations on the peripheral nervous system as the first stage of surgical treatment give good results in most cases.
