Abstract
The authors report a follow-up study on the long-term results of vidian neurectomies performed during the past 10 years at the Jikei University School Hospital.
In the previous study on 71 cases the subjective effectiveness turned out to be 94.4% while the present study showed 97.7% subjective effectiveness both of which are similar with the results reported by others.
Recurrence of milder symptoms in some cases several years after neurectomies was also confirmed by the present study.
The authors discuss reinnervation and regeneration of the autonomic nerves and denervation hypersensitivity as the probable causes of the recurrence of the symptoms.
