Selective denervation of the autonomic nerve supply of the nasal mucosa.

The autonomic innervation of the nasal mucosa has been studied in normal rats and in rats in which the supplying nerves had seen selectively transected; postoperative survival times varied from 2 weeks up to 18 months. The vascular structures appeared to be innervated both by acetylcholinesterase- and noradrenalin-containing fibres. Furthermore a nerve plexus consisting of both types of fibres was observed in the subepithelial region.
