    I would like to ask if are any evidence that PSOM can cause facial nerve paralysis? I mean what is the anatomo-pathological mechanism?

      In one report of 61 dogs with PSOM (Stern-Bertholtz, et al, JSAP 2003), 15 dogs (24.5%) had nervous system signs (ataxia, facial paralysis, nystagmus, head tilt or seizures). I’m not sure it’s been definitively proven, but most sources state that facial paralysis is due to secondary inflammation affecting the facial nerve as it passes through the facial canal.
