[Evaluation of long-term results of vidian neurectomy in the treatment of perennial rhinitis].

Vidian neurectomies by transnasal and transseptal approaches were performed on 21 patients with perennial rhinitis and with a follow-up of 5 years. The results showed that sneezing and watery rhinorrhea relapsed in 85.7% of the operated series and 66.7 per cent in one year after operation. The causes of recurrence were discussed and analysed. We consider that symptoms of sneezing and watery rhinorrhea are induced by a series of factors so that the efficacy of single vidian neurectomy needs further evaluation.
