    abstract = {Sparse evidence of the potentialities of surface stimulation (ES) for preventing muscle atrophy in patients with acute or chronic facial palsy have been published so far. Especially studies addressing objective imaging methods for paralysis quantification are currently required. Facial muscles as principal target of ES can be directly quantified via ultrasound, a swiftly feasible imaging method. Our study represents one of the few systematic evaluations of this approach within patients with complete unilateral facial paralysis. Methods A well-established ultrasound protocol for the quantification of area and grey levels was used to evaluate therapeutical effects on patients with facial paralysis using ES. Only patients with complete facial paralysis confirmed by needleelectromyography were included. Individual ES parameters were set during the first visit and confirmed/adapted every month thereafter. At each visit patients additionally underwent facial needle-electromyography to rule out reinnervation as well as ultrasound imaging of 7 facial and 2 chewing muscles. Results In total 15 patients were recruited (medium 53 years, min. 25, max. 78; 8 female, 7 male). They underwent ES for a maximum of 1 year without serious adverse events. All patients were able to follow the ES protocol. First results in the assessment of ultrasound imaging already indicate that electrically stimulated paralytic muscles do not experience any further cross-sectional area decrease in comparison to the contralateral side. Non-stimulated muscles do not provide significant changes. Similar effects on grey levels currently remain to be assessed to draw further conclusions. Conclusion ES is supposed to decelerate the process of atrophy of facial muscles in patients with complete facial paralysis. Thus, the muscular cross-sectional area does not seem to aggravate during the period of electrostimulation within sonographic assessment. This demonstrates the benefit of ES regarding the facial muscle atrophy in patients with complete facial paralysis.},
