Pattern Overview

Wind-Cold Attacking the Collaterals is the core pattern in acute Bell's

palsy, characterized by **facial nerve edema compressing the facial

nerve, sudden facial paralysis, facial cold pain, ear pain, chills, and

neck stiffness. The core pathogenesis is invasion of Wind-Cold

pathogens into the facial Yangming collaterals**, causing nerve edema,

ischemia, and facial muscle paralysis.

Western Mechanism Reference

Facial nerve edema compressing the facial nerve, with increased

intraneural pressure and nerve ischemia. Wind-Cold Attacking the

Collaterals corresponds to acute Bell's palsy, where viral reactivation

(HSV-1) and nerve inflammation cause facial nerve edema, increased

intraneural pressure, and nerve ischemia.
