Posterior Fossa Rhizotomies

  • Ludwig G. Kempe


Since 1955 we have used the posterior fossa approach exclusively in the surgical treatment of tic douloureux. This exposure is preferable because, as Dandy 1 pointed out many years ago, light touch is preserved in all three divisions. This means that the corneal reflex is not disturbed. It would also seem that this is a less hazardous approach as far as injury to the motor root is concerned. Because tic douloureux may result from compression of the nerve roots by various causes, this route also offers the advantage, in these cases, of exposing the pathology.
