Inclusion criteria for assessment of facial function by three\u2010dimensional video analysis were preoperative and postoperative (&gt;18\u2009months) video sets for facial marker tracking, which were available in 63 patients. Demographic factors and treatment concepts were analyzed and correlations to functional outcomes calculated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One hundred and twenty\u2010eight patients with iatrogenic facial palsy underwent facial reanimation procedures and were included in this study. The mean duration of facial palsy was 7.8 years. The most common procedures leading to iatrogenic facial palsy were acoustic neuroma resection (29.7%), parotidectomy (21.1%), and brainstem\/cerebellopontine angle tumor resection (21.1%). Selected functional results were significantly improved after facial reanimation surgery. The mean lagophthalmos during eyelid closure reduced from 7.3\u2009\u00b1\u20094.1 mm to 5.4\u2009\u00b1\u20094 mm (<jats:italic>p\u2009&lt;<\/jats:italic> .001). The function of the mouth was significantly improved, both statically (static asymmetry: 10.3\u2009\u00b1\u20097.6 mm preoperatively, 0.8\u2009\u00b1\u20099.5 mm postoperatively; <jats:italic>p\u2009&lt;<\/jats:italic> .001), and during smile movement (\u201cDynamic Symmetry Index\u201d: 0.16 preoperatively, 0.39 postoperatively; <jats:italic>p\u2009&lt;<\/jats:italic> .001). The mean duration of facial palsy correlated with postoperative smiling function (<jats:italic>r<\/jats:italic>\u2009=\u2009.358, <jats:italic>p<\/jats:italic>\u2009=\u2009.011).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Facial reanimation significantly improves facial function in iatrogenic facial palsy.
