    Introduction Recently, the therapeutic effects of electrostimulation have been increasingly investigated, also in the field of facial palsy. We are currently testing the possibility to conduct selective surface stimulation of the M. zygomaticus (ZYG) in patients suffering from complete facial paralysis (CFP)

    Methods 5 patients were recruited. They underwent surface electrostimulation for a maximum of 1y, twice a day for 15min (5min pause every 5min stimulation). The parameters were set during the first visit and confirmed/adapted every month thereafter. At each visit the patients underwent 3D photos, electromyography, ultrasound, magnetic resonance controls, and Sunnybrook evaluation, and answered the FaCE and FDI questionnaire.

    Results From the start up to 1-year follow-up, it was possible to find a combination of pulse width (PW) and amplitude compatible with comfortable ZYG-specific activation. The best results were obtained with a triangular wave form stimulation at a PW between 100 and 250ms and an amplitude = 5mA. On average a higher amplitude was necessary to selectively activate the ZYG response in patients suffering from CFP for =5y than in patients freshly diagnosed. Sunnybrook results significantly (p=0.04) improved after 6m stimulation. FaCE (total score) showed a significant (p=0.04) improvement already after 2m, while the social component of the FDI significantly (p=0.04) improved after 7m

    Conclusions Our work showed that ZYG-selective electrostimulation is possible, safe, and effective over time. The stimulation protocol, in particular the applied amplitude and PW, shall be carefully selected based on the CFP duration. Patients were extremely compliant with the treatment protocol and received a significant improvement in their quality of life
