I do NOT think ultrasound therapy is of benefit in case of facial nerve .Yes, i tried to find an evidence supporting the side effects of ultrasound on nerve ,i fail now to find what i have seen before ,on contrary i found researches saying ultrasound could enhance regeneration .
From my experience in dealing with facial , i refute completely ultrasound using , those patients need to learn only what could causes residuals , all those electrotherapy could cause cross-wiring in both the nerve and cortical presentations .Which means you find the patient,s face moves automaticallly interconnected ,no control of indiviudal motions and experssions .
