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

KEY POINTSAutonomic 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.

Automated summary

Autonomic nerve densities are equal in posterior nasal (PNN), posterolateral nasal (PLNN), and anterior ethmoid nerves (AEN). Rhinitis studies should investigate the efficacy of transecting PLNN and/or AEN in addition to PNN alone.
