Cadaveric analysis of autonomic nerve fiber density in posterior nasal, posterolateral nasal, and anterior ethmoid nerves

Abstract

Autonomic nerve densities were equivalent in posterior nasal (PNN), posterolateral nasal (PLNN), and anterior ethmoid nerves (AEN). Rhinitis studies should explore the utility of PLNN and/or AEN transection over PNN alone.
